This article is based on an official press release from Daher.

The commercial aviation sector is currently facing a massive backlog of aircraft orders, placing unprecedented pressure on the supply chain to produce composite parts faster than ever before. On March 3, 2026, French aerospace manufacturers Daher announced a significant industrial breakthrough designed to address this exact bottleneck. Through a collaborative trial with advanced composites company Hexcel, Daher successfully demonstrated a “Fast Cure” Resin Transfer Molding (RTM) process that drastically accelerates production rates.

According to the official press release, this new methodology allows aerospace-grade composite parts to be manufactured at high speeds without the traditional requirement of multiplying expensive, large-scale manufacturing equipment. By shifting the focus from expanding physical infrastructure to accelerating the chemical curing process, the partnership has provided a viable pathway for scaling up production for next-generation Short and Medium Range (SMR) aircraft.

The results of the trial are striking. Daher reports that the Fast Cure process can reduce series production lead times for specific components from 19 days down to just eight days, fundamentally altering the industrial math for aerospace Original Equipment Manufacturers (OEMs).

The Aerospace Production Bottleneck

The Demand for Composites

The aerospace industry relies heavily on composite materials, such as carbon fiber, to reduce overall aircraft weight, improve fuel efficiency, and lower carbon emissions. However, traditional composite manufacturing processes are notoriously slow and resource-intensive. Standard Resin Transfer Molding (RTM), which involves injecting liquid resin into a closed mold containing a dry fiber preform and heating it to polymerize, provides excellent automation and complex geometric capabilities, but it struggles to meet modern volume demands.

Scaling Challenges

Industry estimates indicate that some aircraft OEMs are targeting unprecedented production rates, occasionally aiming for up to 100 aircraft per month. Scaling up a standard RTM process to meet these high rates typically requires a brute-force industrial approach: investing in dozens of molds and multiple large heating ovens or massive autoclaves. This traditional method creates severe production bottlenecks and requires massive capital expenditure.

Daher and Hexcel’s “Fast Cure” Innovation

Accelerating the Chemistry

To break the cycle of simply buying more equipment to build more parts, Daher shifted its engineering focus to the manufacturing cycle itself. At the end of 2025, the company temporarily diverted production preforms and injection tooling from their standard serial production flow to test two specialized “Fast Cure” resins developed by Hexcel. According to the provided research data, Hexcel has spent recent years refining these rapid-cure, all-liquid format resins specifically to reduce takt time in high-rate aerospace manufacturing.

The trial utilized two specific Hexcel materials:

  • HiFlow HF640F-2: A resin featuring a 15-minute polymerization (curing) time.
  • HiFlow HF610F-2: A resin featuring a 30-minute polymerization time.

The Isothermal Process

The technological enabler of this successful trial was the implementation of isothermal injection. Daher’s engineers injected the resin at a constant temperature of 180 °C, followed immediately by a short curing phase and hot demolding. Hot demolding allows the composite part to be removed from the mold quickly, facilitating a rapid sequencing of operations that standard processes cannot match.

“By utilizing hot demolding and rapid curing, it becomes possible to process thermoset composites with the speed and agility typically reserved for thermoplastic materials.”

Hard Data: Proving Industrial Scalability

Trial Results and Quality Assurance

Daher’s official release notes that the trial resulted in the successful manufacturing of six “production-type” parts, five utilizing the HF640 resin and one utilizing the HF610 resin. During the process, resin injection times were successfully kept below two minutes.

Crucially, speed did not compromise quality. The demonstrator parts were reintegrated into the plant’s standard downstream processes. Subsequent machining, ultrasonic non-destructive inspection, and geometric conformity checks revealed that the Fast Cure parts were entirely equivalent in quality to those manufactured using the slower, reference process.

Equipment and Lead Time Reductions

The most compelling data points from the trial relate to industrial scalability. At very high production rates, Daher projects that a standard process would require over 30 molds and five ovens. By implementing the Fast Cure process, tooling requirements could be divided by eight, requiring only two molds and two mini-presses to achieve the same output.

Furthermore, the overall lead time for series production of these components could be slashed from 19 days at full rate under the standard process to just eight days using the Fast Cure methodology.

AirPro News analysis

We view this development as a critical enabler for the broader aerospace supply chain. The global Resin Transfer Molding in Aerospace market was valued at approximately $1.73 billion in 2024 and is projected to grow at a Compound Annual Growth Rate (CAGR) of 9.2% through 2033, according to industry market-analysis. This growth is heavily dependent on the exact type of cost-efficient, high-performance manufacturing processes that Daher and Hexcel are pioneering.

Beyond raw speed, the Fast Cure process offers a vital strategic advantage: flexibility. Because the process relies on smaller, less permanent infrastructure, such as mini-presses rather than massive, fixed ovens, manufacturers gain the agility to reallocate equipment to different aircraft programs as market demands fluctuate. While the parts produced in this specific trial were non-airworthy demonstrators, this successful proof of concept lays the necessary groundwork for official certification and widespread industry adoption in the coming years.

Frequently Asked Questions (FAQ)

What is Resin Transfer Molding (RTM)?

RTM is a manufacturing process where liquid resin is injected into a closed mold containing dry fibers (like carbon fiber). The mold is then heated to cure the resin, creating a strong, lightweight composite part commonly used in aerospace.

How much faster is Daher’s Fast Cure process?

According to Daher’s trial data, the Fast Cure process reduces the series production lead time for specific components from 19 days to 8 days, while utilizing resins that cure in as little as 15 to 30 minutes.

2026 GA Parts Survey: Supply Chain Pressures on Aging Fleet

TBX survey finds 66% of GA maintenance pros expect parts availability to worsen as the piston fleet averages 53 years old.

Published

on

General aviation maintenance professionals are spending more time hunting for parts and technical data than managing costs, as supply chain friction threatens the operational viability of an aging piston aircraft fleet.

In a press release issued on August 23, 2026, TBX, operating as Airworthy.com, published the findings of its 2026 General Aviation Parts Survey. The accompanying summary report, titled “The Great Parts Squeeze,” details the mounting pressures on maintenance shops tasked with servicing a certified general aviation (GA) piston fleet that now averages 53 years of age.

Supply chain friction and industry sentiment

The survey data indicates widespread pessimism regarding the near-term outlook for component availability. According to the report, 66% of surveyed industry professionals expect the aviation parts supply environment to worsen in the near future. Dissatisfaction is prevalent across multiple metrics, with 72% of respondents reporting frustration with parts pricing and 59% expressing dissatisfaction with current lead times.

Despite the high concern over pricing, the report highlights that the sheer time required to source components and access Illustrated Parts Catalogs (IPCs) has become the primary operational bottleneck for maintenance providers.

“Maintenance shops are spending too much time searching for parts, finding part numbers, waiting on backorders, and sourcing alternatives,” said Jon McLaughlin, CEO of TBX.

McLaughlin added that this administrative burden includes the time spent explaining limited options, or the complete lack thereof, to customers waiting for their aircraft to return to service.

Strategies for an aging piston fleet

With the average certified GA piston aircraft now over half a century old, the industry faces compounding challenges in keeping legacy airframes airworthy. The TBX report suggests that maintaining this fleet will require broader acceptance and availability of alternative components, including Parts Manufacturer Approval (PMA) items and serviceable used parts, alongside traditional Original Equipment Manufacturer (OEMs) supplies.

“As the GA fleet continues to age, improving parts availability, expanding access to technical data, and giving maintainers more options will be critical to keeping these aircraft flying,” McLaughlin stated in the release.

The company intends for the survey data to serve as a baseline for manufacturers and suppliers to address these bottlenecks. McLaughlin noted that the friction points identified by maintenance professionals require a coordinated response, stating that the issue cannot be solved by any single segment of the industry alone.

AirPro News analysis

The findings in the TBX report quantify a reality we hear frequently from general aviation maintenance providers. As the legacy piston fleet ages past the 50-year mark, the original supply-chains that supported these aircraft have often consolidated, pivoted to turbine markets, or ceased operations entirely. The high dissatisfaction with lead times points to a structural gap in the market. While PMA manufacturers have stepped in to produce high-demand replacement parts, the long tail of low-volume, specialized components remains a significant vulnerability for GA operators. If supply chain friction continues to outpace solutions, we may see an increase in aircraft grounded not for lack of funds, but for lack of basic hardware and approved technical data.
