Parameters of diff erent types of structures and physical-mechanical characteristics of composites based on domestic polysulfone

Abstract

Using the glass-fi lled composites based on polysulfone domestic brand PSF-190 as an example, the problems of constructing of structure of dispersed-fi lled polymer composite materials (DFPCM) are considered for the fi rst time. The generalized parameters of disperse structures and their classifi cation according to the structural principle are taken into account. It was established for the fi rst time that the complex of physical-mechanical characteristics of DFPCM based on PSF-190 + glass fi ber is determined by the structure, type of lattice, packaging, and generalized parameters. The dependences of the physicomechanical characteristics of DFPCM on the generalized parameter of the dispersed structure (Θ) are given. It has been established that for medium-fi lled disperse systems (Θ = 0,60–0,45 v.f.) maximum physico-mechanical characteristics of the DFPCM are achieved at a content of short glass fi ber of 0,14–0,18 v.f. The compositions of domestic glass-fi lled polymeric composite materials based on domestic PSF-190 with specifi ed types of lattices, structures and generalized parameters, which are practically not inferior to foreign analogues by a set of operational properties, have been developed.
