The cars of the future will become lighter and cheaper, while also meeting more stringent safety, comfort and design requirements. This requires more use of polymers and composites in high-strength structural parts. GMT materials are an important technology in this regard. Today's seats, dashboards, etc. are all made of GMT. They must be able to absorb considerable loads and a portion of the impact energy generated during a collision. GMT not only provides the properties (modulus, strength, impact resistance, density, etc.), but also depends on the flow molding process, which can be easily processed into complex parts. This is one of its advantages, and it also enables low-cost, mass production Large surface area structural parts are possible. In the past few years, GMT has made many developments and progresses, which can meet the needs of present and future.
GMT material is a new type of engineering plastic, which can be widely used in various parts of the car body, can replace traditional metal parts, reduce weight and cost. GMT is a composite material with thermoplastic resin as the matrix and glass fiber felt as the reinforcing skeleton. Generally, a semi-finished sheet can be produced and then directly processed into a desired shape. The fiber can be chopped glass fiber or continuous glass fiber mat, and the thermoplastic resin can be general-purpose plastic, engineering plastic or high-performance plastic.
