Toray Advanced Composites (Morgan Hill, Calif., U.S.) is featuring its latest product developments in thermoset and thermoplastic technologies. This includes the newly introduced Toray TC346 high-temperature epoxy component prepreg and Toray Cetex TC1225 low-melt polyaryletherketone (LM PAEK), which was the first thermoplastic unidirectional (UD) tape qualified by the National Center for Advanced Materials Performance (NCAMP).
Toray says Toray TC346 was developed for rigorous structural applications within Formula 1, NASCAR and high-performance automotive and motorsport markets. It recently passed the SFI 56.1 and UL94 V0 flame-retardancy tests, which Toray says makes this product suitable for applications like gearbox and suspension components. The system is said to offer a superior surface finish for aesthetic appeal and controlled flow of the resin to simplify layup and curing production. It is also suitable for applications requiring high glass transition temperatures, high compression strength and high fracture toughness, Toray says. Toray TC346 is available in a variety of unidirectional tapes and fabric styles.
Toray Cetex TC1225 is a high-performance structural thermoplastic composite material that uses a semi-crystalline engineered PAEK resin for mechanical performance. Compared to other PAEK systems, this material is said to exhibit superior processability due to a low melt viscosity and reduction in processing temperature by 50–75°C (122–167°F). It can be used with automation tape laying (ATL) and automated fiber placement (AFP) methods, and is said to demonstrate rapid cycle times enabling cost-efficient, high-rate production.
The company is also featuring its portfolio of advanced composite materials: thermosets, Toray Cetex thermoplastics, Toray AmberTool tooling prepregs, Toray MicroPly complementary accessory products and compression molded parts through the CCS group.

Next-generation aerospace programs demand higher temperatures for structural and hot-section components, fostering advances in thermoset resin chemistry.
Compared to legacy materials like steel, aluminum, iron and titanium, composites are still coming of age, and only just now are being better understood by design and manufacturing engineers. However, composites’ physical properties — combined with unbeatable light weight — make them undeniably attractive.
