Structural Components

The composites GMT and GMTex developed by Mitsubishi Chemical Advanced Materials Composites make it possible to replace structural and semi-structural vehicle parts made of metal with lighter, fabric-reinforced composite components.

These innovative materials are already firmly established in large-series production. Among others, bumper brackets, battery cases and even body parts like the front end are made from GMT or GMTex.

The composite-only solution without additional steel reinforcement in series production is possible because the reinforced thermoplastic composite materials display extremely good material properties in terms of rigidity, strength, dimensional stability and crash performance.

The use of GMT and GMTex always yields weight savings, fewer production steps in series production and greater design freedom.
