1.High specific strength: The strength of GMT is similar to that of hand lay-up polyester FRP products, and its density is 1.01-1.19g/cm, which is smaller than that of thermosetting FRP (1.8-2.0g/cm), so it has higher specific strength .
2. Lightweight and energy-saving: The dead weight of the car door made of
can be reduced from 26Kg to 15Kg, and the thickness of the back can be reduced to increase the car space, and the energy consumption is only 60%-80% of steel products , 35%-50% of aluminum products.
3. Compared with thermosetting sheet molding compound made of SMC fiberglass roving
, GMT material has the advantages of short molding cycle, good impact performance, recyclability and long storage cycle.
4.Impact performance: GMT's ability to absorb shock is 2.5-3 times higher than that of SMC. Under the action of impact force, dents or cracks appear in SMC, steel and aluminum, while GMT is safe and sound.
5.High rigidity: GMT contains fiberglass fabric
, which can keep its shape even if there is a 10mph impact collision.
