Long Fiber Reinforced Thermoplastics (LFT or LFRT) as high performance and high strength polymer composites was wildly used in the fields of automotive industry/machinery/electronic/communication/military/Sports equipments/medical equipments etc. In recent years, there has been a rapid and steadily growth in the use of LFT all over the world. This has been achieved due to their great and potential of combing high performance/price ratios-such as reduced weight, corrosion resistance, great design and styling flexibility especially, with rapid clean process and the attraction of their intrinsic recyclables. So LFT was called green composite materials now.
