TCR Composites (Ogden, Utah) highlights the release of its high glass transition temperature (T_g) resin, an epoxy resin system engineered to meet and exceed the demands of advanced rotor and aerospace applications. Developed with industry partners in mind, the resin has improved thermal performance, optimal mechanical properties and simplified processing.

With the rotor industry requiring high thermal and mechanical performance, TCR’s resin delivers a dry T_g exceeding 230°C (446°F), achieved with a simple out-of-autoclave (OOA) cure at just 177°C (350°F).

Extreme thermal performance. TCR’s T_g resin achieves a DMA storage modulus (E’) onset T_g > 45°C (81°F) and a Tan Delta peak T_g > 56°C (100°F) above its cure temperature, made possible by a 100% epoxy chemistry and ultra-high cross-link density formulation.

Room temperature storage. This resin offers a 3-month room temperature prepreg shelf life, with potential for longer durations as ongoing evaluations continue, simplifying logistics and reducing cold storage requirements.

Tailorable tack and flow. It maintains customizable handling characteristics, making it ideal for complex part geometries and hand layup operations.

High strength with flexibility. Demonstrates optimal tensile elongation and flexural strength, even when used with intermediate modulus fibers such as IM10 and T1100.

TCR Composites is a global thermoset resin systems company, known for providing high-performance prepreg materials tailored to the needs of aerospace, defense and industrial markets.
