摘　　要：研究硫酸钙晶须用量对低熔点PA6复合材料力学性能和热性能的影响。结果表明:随着硫酸钙晶须用量的增加,低熔点PA6的缺口冲击强度先增加后降低,最高值为6.9 kJ/m2;拉伸和弯曲强度则先增加,后趋于稳定,拉伸强度的最高值为94.9 MPa,弯曲强度的最高值为116.8 MPa;低熔点PA6的维卡软化点则随着硫酸钙晶须用量的增加而增加。The effects of CaSO4 whisker contents on the mechanical properties and thermal performance of low melting point PA6 were studied. The results showed that the Izod impact strenth of low melting point PA6 increased by adding CaSO4 whisker impact strength firstly increased to 6.9 kJ/m^2 , and then decreased. The tensile strenth of low melting point PA6 firstly increased to 94.9 MPa,bending strenth of low melting point PA6 firstly increased to 116.8 MPa, and then steady. The Vieat softening point of low melting point PA6 always increased.
