【Abstract】 Random short fiber enhanced composites is largely in use, the paper discuss a method for predicting its elastic modulus rapidly. Under concept of equivalent differential medium, equivalent gravel theory in infinity elastic body, and precept of selfconsistent for predict the modulus of composite materials, the paper establishes the differential functions for computing modulus of these composites. These functions are nonlinear coupling differential functions, could via the numeric solving method get the results, the elastic modulus of random short fiber enhanced composites.更多还原
