Abstract

This article deals with the impact of short glass fiber (GF) on the performance of 60/40 wt% of polyamide 6/polyamide 12 (PA6/PA12) blend. The short fiber-reinforced composites were fabricated by using melt compounding via twin screw extruder and injection molding. The morphological, water uptake, rheological, thermo-mechanical, and mechanical properties of the composites were discussed. The morphological observations show that the PA6/PA12 blend exhibited compatible morphology and also adhesion between the fiber and matrix was quite strong. The tensile strength/modulus and storage modulus of the blend were substantially improved with GF reinforcement as a result of these morphological findings. While the water uptake of neat PA6 decreased significantly after blending with PA12, the incorporation of GF further reduced the water uptake of the PA6/PA12 blend. The thermomechanical analysis showed the enhancement of the stiffness of the composites and also glass transition temperature increment.

短玻璃纤维增强聚酰胺复合材料的制造和性能

本文探讨了短玻璃纤维（GF）对 60/40 wt%聚酰胺 6/ 聚酰胺 12（PA6/PA12）混合物性能的影响。短纤维增强复合材料是通过双螺杆挤出机熔融共混和注塑成型制成的。对复合材料的形态、吸水性、流变学、热力学和机械性能进行了讨论。形态观察结果表明，PA6/PA12 共混物呈现出兼容形态，纤维与基体之间的粘附力也相当强。由于这些形态学发现，在添加 GF 增强材料后，共混物的拉伸强度/模量和存储模量得到了大幅提高。与 PA12 共混后，纯 PA6 的吸水率明显降低，而 GF 的加入则进一步降低了 PA6/PA12 共混物的吸水率。热力学分析表明，复合材料的刚度提高了，玻璃化转变温度也提高了。
