通过制备金属纤维纱线与环氧树脂两相复合结构的金属纤维纱线,对金属纤维纱线进行比热容、纤维轴向和径向热导率、电导率测试。结果表明:金属纤维的加入,会提高纱线的热导率及电导率,在金属纤维含量相同的情况下,纺纱方式对金属纤维纱线的热导率及电导率的影响不大。当不锈钢纤维含量为30%时,样品Y8混纺纱的电导率达到3.91×10³S/m,轴向、径向等效热导率分别为1.5929、0.4847W/m·℃。

A metal fiber yarn with two phase composite structure of a metal fiber yarn and an epoxy resin was made.The specific heat capacity of yarn,fiber axial and radial thermal conductivity,as well as electrical conductivity were tested.The results showed that the addition of metal fiber increased the thermal conductivity and electrical conductivity of yarn.In the case of the same metal fiber content,the spinning method had little effect on the thermal conductivity and electrical conductivity of yarn.When the content of stainless steel fiber was 30%,the conductivity of Y₈ blended yarn was 3.91×10³S/m.The axial and radial equivalent thermal conductivity of yarn were 1.5929 and 0.4847W/m·℃ respectively.
