Effect of chemical nature of matrix on the strength of bonds with Armos aramide fibers

Abstract

This investigation deals with adhesion between high-strength and high-modulus Armos aramide fibers (polyheteroarylene-co-p-phenyleneterephthalamide ) In [1][2][3][4], adhesion of thermosetting matrices to fibers based on rigid chain polymers (aramide SVM, VMN-88, and PBT polybenzothiazole fibers) was investigated. The data obtained allowed us to choose matrices for producing high-strength and high-modulus organoplastics with specified properties. For SVM polyheteroarylene fibers, the rules linking the mechanical characteristics of reinforced plastics with the interface strength in bonds of their components were determined. In this study, which is a continuation of a series of papers, adhesion of binders to Armos fibers is analyzed.
