摘要
国际上关于热致液晶高分子(TLCP)原位复合材料的报道始于80年代,原位复合增强材料的增强形式不是在树脂加工前实际存在的,而是在加工过程中形成的,原位复合的方法是将TLCP掺入树脂基体,使其在特定的流场和应力场作用下。
The relationship between the microstructure developed during injection molding of a PES/TLCP blend and its properties was investigated . The resulting injection molded structure had a distinct skin-core morphology, where TLCP fibres composed the skin layer and sherical and ellipsoidal particles or 'stalamite'ones comprised the core section . The blend exhibits excellent mechanical properties due to in situ formed fibers of the disperse TLCP phase in PES matrix. The blend tensile strength reduces with increasing the melt temperature and the shear rate.
