Construction of a monolithic 1D structure of reinforced plastics with different types of structures and properties

Abstract

For the first time, it has been shown that the unified structure of reinforced polymer composite materials (RPCM) includes a heterogeneous structure of continuous fiber in space, free volume and a polymer matrix consisting of three functional components (B + M) + Θ, which determines both technological and operational properties. The relationship between the coordination number (Z) of the heterogeneous structure of continuous fiber and the parameters of the polymer matrix B and Θ has been established, which made it possible to propose a classification of RPCM by the structural principle using the parameters Z and Θ, which practically coincides with the data of the previously carried out classification by the reduced geometric parameter a_ср.f/d_f. The content of fibrous filler and the compositions of RPCM for different types of structures can be calculated using the proposed formulas and structural parameters Z and Θ, which simultaneously takes into account the construction of a heterogeneous 1D structure of continuous fiber and a polymer matrix.
