Study on Long Glass Fiber Reinforced ABS Composite by In-situ Polymerization

In-situ polymerization is introduced to produce long glass fiber reinforced ABS composite in this paper. The DSC, degree of grafting and SEM are used to investigate the structure of ABS prepared by in-situ polymerization. And the SEM, tensile strength, impact strength, bend strength test is used to characterize the structure and properties of long fiber reinforced ABS composites. The results show that the structure of ABS prepared by in-situ polymerization is similar to that of the commercial ABS, the good wetting in composite is reached, and the mechanical properties of composites are greatly improved by the in-situ polymerization process.
