PREPARATION AND PROPERTIES OF QUARTZ FIBER REINFORCEDPOLY(SILYLENE-ARYLACETYLENE) RESIN COMPOSITES

Abstract

Abstract: In order to reinforce the mechanical properties of quartz fiber reinforced poly(silylene-arylacetylene) resin (QF/PSA) composites, the paper changed the structure of fabrics and the diameter of quartz fibers to study their impacts on the mechanical and electrical properties of the composites. QF/PSA composites were prepared by compression molding with five kinds of quartz fiber fabrics, including 3D vertical-crossed woven fabrics, 3D face-core woven fabrics, 3D curved shallow-crossing linking fabrics, 2D structure woven fabrics and 2D twill fabrics (woven by 7.0μm and 7.5μm). The effects of the woven structure and the fiber diameter on the mechanical and electrical properties of the composites were studied by testing the flexural strength, flexural modulus, interlaminar shear strength (ILSS) and dielectric constant. The results show that the mechanical properties of the composites which are reinforced by 7.0μm quartz fibers are better than those of the 7.5μm quartz fibers, and the mechanical properties of QF/PSA composites with 2D fabrics are better than those with 3D fabrics. Meanwhile, these changes of the woven structure and the fiber diameter do not impact the electrical properties of the composites.

Key words: compression molding, woven structure, PSA resin
