摘要/Abstract

摘要： 通过模压成型工艺制备了石英纤维增强含硅芳炔树脂复合材料,研究了不同纤维直径的石英纤维斜纹布以及不同结构的石英纤维织物增强含硅芳炔树脂复合材料的力学性能和介电性能。研究结果表明,纤维直径为7.0μm的石英纤维增强含硅芳炔树脂复合材料比直径为7.5μm的具有更加优异的常温和高温力学性能。并且,2D石英纤维织物增强含硅芳炔树脂复合材料的力学性能优于3D。而纤维直径和织物结构的改变对该复合材料的介电性能影响不明显。

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
