| Abstract: | Long E-glass fiber roving used in LFT(long fiber reinforced thermoplastics)composites was studied and successfully fabricated by virtue of mixing polypropylene(PP)with grafted PP and improving surface wetability and the dispersibility of long glass fibers.The LFT specimens were produced by long fiber-granulation technology and injection molding.The results showed that mechanical the proprerties of the compoiste were superior to SFT(short fiber reinforced thermoplastics)with same fiber content.At last,the application prospect of LFT composites was introduced. |
