Toray Celebrates 100 Years with New Aerospace Composite Tech: Fast-Curing Prepreg ‘3960-FC’ and High-Temperature Resin ‘TC1810’ Unveiled at Farnborough Airshow

Jota International Japan

Overview

Toray marked its 100th anniversary by introducing new aerospace composite technologies at the Farnborough International Airshow. Key product launches include “3960-FC,” a fast-curing epoxy prepreg designed to boost production speed, and “TC1810,” a polysiloxane-based ceramic precursor resin developed for high-temperature applications. The company also highlighted its ongoing commitment to sustainability, exemplified by a composite recycling project for end-of-life aircraft that won a JEC Innovation Award.

In Depth

Key Findings

Toray, commemorating its 100th anniversary, unveiled innovative new composite technologies for the aerospace industry at the Farnborough International Airshow. Two standout products are the rapid-curing epoxy prepreg “3960-FC,” designed to dramatically increase production speeds, and “TC1810,” a polysiloxane-based ceramic precursor resin engineered to withstand extremely high temperatures, such as those found around aircraft engines. These advanced materials are set to significantly enhance aircraft performance and manufacturing efficiency.

Technical Details

• Fast-Curing Epoxy Prepreg ‘3960-FC’

  The “3960-FC” prepreg substantially reduces cure times compared to conventional aerospace-grade prepregs. This innovation shortens the manufacturing lead time for aircraft components and improves production throughput, enabling aircraft manufacturers to meet increasing demand while simultaneously reducing production costs. This technology offers significant advantages, especially for single-aisle aircraft that require high-volume production, and for new aircraft development where rapid prototyping is essential. It maintains the high reliability, strength, and durability characteristic of traditional Toray products, all while boosting productivity.

• High-Temperature Polysiloxane-Based Ceramic Precursor Resin ‘TC1810’

  “TC1810” is a polysiloxane-based ceramic precursor resin specifically designed for components exposed to extreme heat, such as aircraft engine nacelles, exhaust systems, and surfaces of high-Mach vehicles. This material maintains excellent structural stability and mechanical properties even in high-temperature environments exceeding 200°C, a range where conventional resin-based composites typically struggle. As a ceramic precursor resin, it can be converted into high-performance ceramic matrix composites through heat treatment, making it an indispensable material for the development of next-generation aircraft and space exploration vehicles that demand superior heat resistance, oxidation resistance, and wear resistance.

Background & Industry Context

The aerospace industry faces stringent demands for improved fuel efficiency, reduced CO2 emissions, and the adoption of sustainable manufacturing processes. Lightweight, high-performance composite materials are key to addressing these challenges, and Toray has been a leader in this field for decades. The launch of these new products underscores the company’s continuous commitment to technological innovation. Furthermore, Toray actively invests in composite recycling technologies, demonstrating a commitment to enhancing sustainability across the entire product lifecycle, as evidenced by its JEC Innovation Award for a project on recycling end-of-life aircraft composites.

Strategic Significance & Outlook

The “3960-FC” and “TC1810” technologies will provide aircraft manufacturers with new design flexibility and improved manufacturing efficiency, accelerating the development of next-generation aircraft. Particularly, alongside the transition to Sustainable Aviation Fuels (SAF), the lightweighting and high-performance enhancement of airframes are crucial for achieving the aerospace industry’s decarbonization goals. These new technologies from Toray are expected to further expand the frontier of material solutions in aerospace, contributing to a future of safer, more efficient, and environmentally conscious aviation.
