description | Fully end-capped silicon-containing arylacetylene (FEC-PSA) terminated with phenylacetylene was prepared in terms of Grignard route. A low viscosity PSA resin for resin-transfer molding (RTM) process was prepared by blending FEC-PSA and PSA. A silane coupling agent triethoxy(acetenyl)silane (TEOAS) was synthesized as a quartz fiber (QF) surface modifier. RTM process was used to fabricate the quartz fabrics reinforced blended PSA composites. The processing performance and thermal properties of the blended PSA, surface of the quartz fibers and the mechanical properties of the composites were investigated. The results show that the blended PSA resin has not only highly heat-resistance, but also good processing performance. XPS analyses indicate that the surface of QF is grafted by ethynyl groups. The interfacial strength between the surface of QF treated by TEOAS and the blended PSA resin is improved. The flexural strength and interlayer shear strength (ILSS) of the interfacial strengthening composites are increased by 28.8% and 25.4%, respectively, compared to the pristine composite without TEOAS-treated QF. |
