Effect of PP-g-GMA on Mechanical Properties of Long Glass Fiber Reinforced PP Composites

Using the melt impregnation device,long glass fiber reinforced polypropylene were produced. Effect of PP-g-GMA on the mechanical properties of the long glass fiber reinforced composite was studied. The results showed that PP-g-GMA affected mechanical properties of long glass fiber reinforced PP composites;when the content of PP-g-GMA was 1%,PP/LGF composites obtained the best mechanical properties,tensile strength,flexural strength and Notched Izod impact strength increased respectively by 32.34%,27.38%and 74.51%.
