Development of Composites with Negative Thermal Expansion Property Using High Performance Fibers

摘要：

Almost all materials exists positive thermal expansion property.However,in many engineering deigns,the material property with negative thermal expansion are needed.High performance fibers have excellent characteristics,such as high strength,remarkable thermal and electrical conductions.Moreover,some of those fibers may exhibit negative thermal expansion property.Therefore,we may develop high performance fiber-reinforced composites with negative thermal expansion by using the optimum combination of the fiber reinforcement and the polymer matrix.This work focuses on developing the high performance fiber-reinforced composites with negative or low thermal expansion property by using the four high strength fibers,polyethylene fiber Dyneema(R) PBO fiber Zylon(R) carbon fiber Torayca(R)and aramid fiber Technora(R) The results showed newly developed composites of Dyneema(R)fiber and Zylon(R)fiber exhibited obvious negative thermal expansion property.The size stability of structural products can be obtained by controlling the coefficient of thermal expansions.
