"Prediction of physical properties of multicomponent composite materials with polymer matrix and multimodulus nonlinear elastic matrix"
Incoming article date: 24.06.2022An engineering technique for predicting the main physical characteristics of multicomponent composite materials with a polypropylene matrix is described. The technique is based on the calculated dependences obtained for a binary composite. Calculation formulas for determining the modulus of elasticity and Poisson's ratio of an artificial material are given. An algorithm for applying the proposed formulas is described, which consists in successively obtaining the desired characteristics, each time considering a two-component composite and taking as the initial material a composition of a polymer matrix and one of the fillers. A specific example shows that the order in which fillers are taken into account does not affect the final result. The proposed technique can significantly reduce the design time for new materials and will make it possible to reduce the number of real experiments. The difference between the theoretical results and the data of physical experiments does not exceed 10–15%.
