Relationship between Porosity and Mechanical Properties of Composite Materials with Elastomer Matrix

Abstract

The relationship between the porosity coefficient and the mechanical characteristics of composite materials obtained by SKN-40 latex treatment of non-woven needle-punched fabric from a mixture of fibers with a linear density of 0,33 and 1,7 tex. Compared with an unpeeled fabric, the porosity coefficient of a composite material with a maximum degree of impregnation equal to 0,3 decreased by 5%, and the effective modulus, which was used to assess the tensile strength of composite materials, increases 7 times in the transverse direction and 3 times in the longitudinal direction.
