  Pp Plastics account for more than 50 % of non-metallic materials in cars because of their light weight, excellent performance and recyclability. Glass fiber reinforced PP(GMT) has become a rapidly developing fibre-reinforced thermoplastic in the past few decades and has been widely used in automotive structures and unbonded components. Because of the high melt viscosity of thermoplastic polymer, the fiber is difficult to disperse into the matrix, so the polymer melt can not penetrate into the inner wet fiber of the fiber bundle. If reinforced shear or high pressure is applied to realize single filaments dispersion of the fiber bundle, the fiber length will decrease. In the mid-1980s, ICI succeeded in producing long fiber reinforced thermoplastic granule(LFTG) using a process similar to cable-coated extruder impregnation, and then moulding or molding. Starting in the 1990s, direct fiberglass reinforced thermoplastic(LFT-D) began to enter the laboratory production phase and made considerable progress in entering the commercial sector
