利用单纤维断裂实验方法 ,测试了聚丙烯 (PP) /玻璃纤维 (GF)单纤维复合材料的界面剪切强度 ,研究了 PP/GF单纤维复合材料体系中 ,横晶结构对界面剪切强度的影响。结果表明 ,随着横晶结构的完善 ,界面剪切强度下降 ,当结晶时间较长时 (如长于 10 m in) ,存在横晶结构试样的界面剪切强度下降的幅度大于不存在横晶结构的试样 ,界面横晶结构内晶体间的界面是造成这种结果的重要原因
The interfacial shear strength of polypropylene (PP) / glass fiber (GF) monofilament composites was tested by means of single fiber fracture test. The effects of transverse crystal structure on interfacial shear strength Impact. The results show that with the perfection of transverse crystal structure, the interfacial shear strength decreases. When the crystallization time is longer (for example longer than 10 m in), the interfacial shear strength of the samples with transverse crystal structure decreases more than that without transverse crystal The structure of the sample, the interface between the crystal structure within the transverse crystal structure is an important reason for this result
