The effect of molding conditions on the mechanical properties of glass fiber reinforced in situ polymerizable polyamide6 matrix (I-GFRTP) were investigated by the use of differential scanning calorimeter (DSC), three-point bending tests and Izod impact tests for various types of the composites which were molded at temperatures of 140, 160, 180 and 200°C respectively. The three-point bending test at 160°C revealed the highest strength within all the specimens tested. For Izod impact tests, no correlation between the molding temperatures and Izod impact strength was observed. Furthermore, it was shown that although I-GFRTP has a higher crystallinity than GFRTP of which matrix is PA6 that has already polymerized, impact strength of I-GFRTP is on a level with that of GFRTP.
