Moisture Absorption Drives Carbon Fibre Degradation in Aircraft
Monash and RMIT research finds moisture absorption is the key factor in carbon fibre degradation, validating accelerated ageing tests for aircraft materials.

This article is based on an official press release from Monash University and RMIT.
Moisture Absorption Identified as Primary Driver of Carbon Fibre Degradation in Aircraft
Modern commercial aviation has increasingly turned to carbon fibre reinforced polymers (CFRP) to build lighter, more fuel-efficient Commercial-Aircraft. While these advanced composites are celebrated for their immense strength and resistance to traditional rust, they possess a hidden vulnerability: the slow absorption of environmental moisture during service. According to a recent press release detailing joint research from Monash University and RMIT University, engineers have definitively identified moisture absorption as the most critical factor in how these aerospace materials degrade over time.
The study, published in February 2026 in the journal Composites Part A: Applied Science and Manufacturing, resolves a long-standing debate within the aerospace engineering community. Historically, industry experts have questioned whether high temperatures cause unique types of structural damage to composite materials, or if heat simply accelerates the natural aging process. The new findings confirm that the total volume of moisture absorbed by the material dictates its degradation, overriding the specific temperature or humidity levels present during exposure.
The Mechanics of Hygrothermal Aging
Carbon fibre reinforced polymers are favored in modern Manufacturing because they replace heavier traditional metals like aluminum, offering exceptional durability without the risk of conventional corrosion. However, as noted in the research report, these materials are susceptible to “hygrothermal aging”, a process where prolonged exposure to heat and environmental moisture causes the material to slowly weaken from the inside out.
Microscopic Damage and Fibre Orientation
Utilizing advanced imaging techniques, the research team observed the exact nature of this internal degradation. As the composite materials aged, they developed tiny voids and microscopic cracks. Furthermore, the absorbed moisture caused “interfacial debonding,” which is a weakening of the critical chemical bond between the carbon fibres and the surrounding polymer matrix.
The official press release highlights that the internal geometric arrangement of the carbon fibres plays a massive role in environmental resistance. The researchers found that certain fibre layouts retain their structural integrity significantly better than others when exposed to moisture, making some designs inherently more sensitive to moisture-related degradation.
Validating Accelerated Ageing Tests
To ensure aircraft components will remain safe and functional for decades, aerospace engineers rely on “accelerated ageing” tests. These tests expose materials to extreme environmental conditions to simulate years of wear in a highly compressed timeframe. The Monash and RMIT study provides crucial validation for these industry-standard testing methods.
“What we found is that it’s not the exact ageing temperature or humidity that matters most, it’s how much moisture the material ultimately absorbs,” said Dr. Katherine Grigoriou, a researcher and lecturer at the Monash Department of Mechanical and Aerospace Engineering.
Dr. Grigoriou further explained in the release that understanding moisture buildup allows engineers to reliably predict long-term performance.
“Our results show that accelerated ageing methods can still provide reliable predictions of long-term performance, as long as the moisture content in the material is properly understood and controlled,” Dr. Grigoriou added.
Industry Implications for MRO
The implications of this research extend directly to airline operations and aircraft manufacturing. By establishing moisture absorption as the primary metric for composite degradation, Airlines can develop highly accurate predictive models for material aging. According to the research team, these insights will help engineers design more durable composite structures, improve maintenance strategies, and increase overall confidence in the long-term safety of aircraft components.
AirPro News analysis
At AirPro News, we view these findings as a critical stepping stone for the next generation of aircraft design. As the aviation industry continues its aggressive pivot away from metal toward lightweight composites to save fuel and reduce carbon emissions, understanding the exact environmental limits of these materials is paramount. The confirmation that accelerated ageing tests remain valid, provided moisture is tracked, should offer a sigh of relief to regulatory bodies and Manufacturers alike. Furthermore, the revelation that specific fibre orientations can mitigate moisture damage provides manufacturers with an immediate, actionable pathway to design inherently safer and longer-lasting airframes. We anticipate that future aircraft maintenance schedules will increasingly incorporate advanced moisture-tracking diagnostics to ensure passenger safety over the multi-decade lifespan of commercial jets.
Frequently Asked Questions (FAQ)
What is hygrothermal aging?
Hygrothermal aging refers to the degradation of materials, particularly composites, caused by prolonged exposure to a combination of heat and environmental moisture. In carbon fibre composites, this can lead to the weakening of the bond between the fibres and the polymer resin.
Why do modern aircraft use carbon fibre composites?
Carbon fibre reinforced polymers (CFRP) are exceptionally lightweight, extremely strong, and highly resistant to traditional rust and corrosion. Using these materials instead of heavier metals like aluminum helps aircraft burn less fuel and reduce emissions.
Does high temperature directly damage carbon fibre in aircraft?
According to the recent study by Monash University and RMIT, it is not the exact temperature or humidity that matters most, but rather the total amount of moisture the material ultimately absorbs. Heat primarily serves to accelerate this moisture absorption process.

REGENT Craft Raises $240M Series B to Scale Seaglider Production
REGENT Craft secured $240M in Series B funding to advance Seaglider manufacturing, with first crewed flight and production starting no earlier than 2027.

REGENT Craft secured $240 million in Series B funding on August 27, 2026, providing the capital required to transition its wing-in-ground-effect (WIG) Seaglider vessels from development into full-scale manufacturing. The funding round, split evenly between equity and debt, paves the way for the imminent first human flight of the company’s Viceroy prototype in North Kingstown, Rhode Island.
In a press release issued by the company, REGENT confirmed the investment brings its total raised capital to $340 million. The round was co-led by Mare Liberum, AE Ventures, and Erebor Bank, with participation from defense and commercial stakeholders including Lockheed Martin Ventures and Japan Airlines. The capital injection coincides with the completion of a 255,000-square-foot manufacturing facility and supports a commercial order book reportedly valued at over $10 billion.
Scaling production and certification milestones
The Series B funding marks a definitive shift for the Rhode Island-based manufacturer as it prepares to fulfill existing commercial orders. According to reporting by Tectonic Defense, REGENT co-founder and CEO Billy Thalheimer indicated the company has booked several years of manufacturing capacity and is eager to deliver on firm commercial orders backed by cash deposits.
“This investment marks a critical inflection point for REGENT as we move from development into production,” Thalheimer stated in the press release. “We have built significant momentum across both our defense and commercial pipelines, and this funding enables us to scale manufacturing, execute key certification milestones, and deliver Seagliders to customers.”
Resilience Media reported that full production of the Seagliders is expected to commence no earlier than 2027. The immediate focus remains on executing certification requirements and conducting the first crewed flight operations of the Viceroy platform.
Expanding defense and maritime security applications
While commercial passenger operations form a significant portion of REGENT’s backlog, defense applications have driven substantial investor interest. The company recently secured an expanded $15 million contract with the U.S. Marine Corps for the Viceroy platform. Additionally, REGENT’s autonomous Squire drone recently completed demonstrations at the military experimentation event Silent Swarm.
Thalheimer noted to Tectonic Defense that investor conviction in this round was heavily driven by the company’s expanding defense portfolio. This sentiment was echoed by Marcin Kowalik, General Partner at Balnord. Kowalik told Resilience Media the investment decision was driven by the need for maritime security along NATO’s eastern flank. He noted that the manufacturer’s specific WIG technology will be vital for maintaining safe operations in regions like the Baltic Sea.
AirPro News analysis
The ability to secure $120 million in debt alongside $120 million in equity suggests maturing institutional confidence in wing-in-ground-effect technology. While the broader advanced air mobility (AAM) sector often struggles to transition from prototyping to production due to capital constraints, REGENT’s dual-use strategy appears to be insulating it from market headwinds. We view the U.S. Marine Corps contract and the strategic location of the new 255,000-square-foot facility as indicators that the company is positioning itself as a primary maritime mobility provider for both civilian operators and the Department of Defense. The true test will be navigating the certification framework, as WIG vessels occupy a unique regulatory space between maritime and aviation authorities.

Brussels Airport Trials Autonomous Electric Tow Tractor
Brussels Airport launches its first autonomous electric tow tractor trial in the cargo zone under the EU Stargate programme.

Brussels Airport (BRU) has initiated real-world trials of an autonomous electric tow tractor within its cargo zone, marking the first deployment of self-driving cargo transport at a Belgian Airports.
In a press release issued on August 24, 2026, the airport announced the pilot program in partnership with WFS Cargo and Charlatte Autonom, a joint venture between Charlatte Manutention and Navya Mobility. The trial is part of the European Stargate programme, a five-year initiative funded by the European Green Deal to test sustainable and efficient aviation technologies.
Operational parameters and vehicle specifications
The autonomous vehicle combines a logistics platform developed by Charlatte Manutention with an autonomous driving system from Navya Mobility. Operating on predefined routes between cargo warehouses and the airport aprons, the electric tow tractor is designed to navigate the complex ground environment without an onboard operator.
During the trial phase, the vehicle is restricted to a maximum speed of 12 km/h while in autonomous mode. It has the capacity to tow up to four cargo trailers simultaneously.
“This project with Brussels Airport once again illustrates the expertise of Charlatte Manutention and Navya Mobility in deploying autonomous mobility solutions within complex and demanding airport environments,” said Jean-Claude Bailly, CEO of Navya Mobility. “Safety and reliability are paramount in the design of our products, whose technology enables fully autonomous operation, without an operator on board, when regulatory conditions allow.”
Cargo volume context and Stargate integration
The Automation trial arrives during a period of high cargo throughput for Brussels Airport. The facility handled nearly 420,000 tonnes of Cargo-Aircraft in the first half of 2026, representing an 8.3% increase compared to the same period in 2025. While July 2026 saw a slight 3.2% decline to 66,600 tons due to drops in trucked replacement traffic and express services, full cargo charters and belly cargo volumes continued to grow.
The autonomous tractor pilot is a key deliverable in the fifth and final year of the Stargate programme. Launched in November 2021, the €24.8 million initiative is led by Brussels Airport and includes a consortium of 22 partners focused on mobility, energy, and technology solutions.
“At Brussels Airport, we continue to explore innovative and sustainable solutions that can tangibly strengthen cargo operations,” said Arnaud Feist, CEO of Brussels Airport. “Thanks to this project, we can gain valuable insights into the potential of autonomous technologies, and into what they can deliver in terms of efficiency and Sustainability, while people remain key to operations and the highest Safety standards are maintained.”
AirPro News analysis
We view the deployment of autonomous ground support equipment as a necessary evolution for major cargo hubs facing persistent labor constraints and ambitious emissions targets. The controlled, highly regulated environment of an airport apron provides an ideal testing ground for geofenced autonomous vehicles. By limiting the initial trial to predefined routes and a strict 12 km/h speed limit, Brussels Airport and its partners are prioritizing safety data collection over immediate operational throughput. If successful, this pilot could establish a regulatory and operational framework for broader autonomous ground handling adoption across European airports.
