| Abstract: | The mechanics properties and the thermal conductivity of a kind of thermally conductive fiber/epoxy resin unidirectional layer composite were researched in this paper.Then,it was found that the thermal conductivity of the high conductivity fiber/epoxy resin unidirectional layer composite increased while the performance of individual composites decreased.It is considered that the interface functions of the thermally conductive fiber and epoxy resin are an important factor affecting the mechanical properties of composite materials.Moreover,the surface micro-morphology,surface chemistry characteristics and crystallinity of the high thermal conductivity fiber were discussed,and the mechanical properties of the thermally conductive fiber/epoxy resin impregnated yarn were researched. |
