Environmental protection and lightweight are the general trends of transport. Engineers find that composite material is light weight, high strength and rigidity, which can reduce vehicle weight, lower noise and improve the safety.

Topweaving 3D fiberglass fabric with the sandwich structure material is mainly used in wall panel,roof, door, floor. The weight of 3D fiberglass fabric is 30%-60% lighter than traditional material, So it can effectively reduce the vehicle weight. In addition, the 3D fiberglass fabric offer superb properties, such as outstanding performance in resistance to delamination (Excellent delamination suppression), Simple and effective lamination process, thermal and sound insulated.; fire retardant; wave transmittable and so on.
