短玻璃纤维增强低熔点尼龙6复合材料的性能研究

Properties of short glass fiber reinforced low melting point PA6 composite

研究了短玻璃纤维用量对低熔点尼龙6(LMPA6)复合材料力学性能和热性能的影响。结果表明:随着短玻璃纤维用量的增加,LMPA6的缺口冲击强度先增加后降低,最高值为6.46KJ/m2;拉伸强度和弯曲强度则随之提高,当短玻璃纤维的用量为30%时,拉伸强度提高到100MPa,弯曲强度提高到130MPa以上。LMPA6的维卡软化点也随短玻璃纤维用量的增加而提高,当短玻璃纤维的用量为30%时,维卡软化点提高到90℃。

The effects of short glass fibres contents on the mechanical properties and thermal performance of low melting point PA6 （LMPA6） was studied. The results show that the Izod impact strength of LMPA6 increased by adding short glass fibres, impact strength firstly increased to 6.46KJ/m2, and then decreased. The tensile strength and bending strength of LMPA6 always increased..When the content of short glass fibres increased to 30%, the tensile strength increased to100MPa, and the bending strength increased to more than 130MPa. The Vicar softening point of LMPA6 always increased. When the content of short glass fibres increased to 30%, the Vicat softening point increased to 90℃.
