Hexcel is working with NaCa Systems, a Tier 1 supplier of natural fiber composite automotive interior components, to develop a lightweight carbon fiber prepreg and a wood fiber composite sports car seat back using a rapid compression molding process

This innovation validates a short cycle production process for the production of CFRP and wood fiber composite parts, which offers many advantages for automakers

Hexcel supplied NaCa Systems with an optimized version of its HexPly M77CS epoxy prepreg

HexPly M77CS is a fast-curing, hot-melt, thermoset epoxy matrix material designed for prepreg applications requiring short cure cycles and a smooth, aesthetically pleasing surface

While resin absorption is slightly higher with natural material components, Hexcel's newly developed M77CS prepreg has increased resin content to optimize the bond strength of CFRP to wood fiber composites

This carbon fiber prepreg cures in 4 to 5 minutes at approximately 145˚C and is compatible with NaCa Systems' existing production lines and metal molds

Compared to typical injection-molded plastic parts, this lightweight seat back is 40% lighter and CO2 emissions are significantly lower compared to full carbon _fiber parts

Unlike plastic moldings, this prepreg and wood fiber structure does not produce sharp fragments when damaged, improving occupant safety in a crash
.

In addition, wood fiber composites have improved sound absorption properties, helping to improve NVH performance in vehicle interiors

At JEC World 2020, Hexcel will display seat backs from NaCa Systems at its booth
