摘要:
碳纤维与玻璃纤维混杂增强树脂基复合材料可以发挥碳纤维的高强、高模、耐疲劳性能与玻璃纤维的高应变、低成本等优势,满足工程结构应用需求.本文针对碳-玻璃纤维混杂增强环氧树脂基复合材料拉挤杆,发明了一套高效挤压-摩擦型锚固系统用于杆体力学测试,研究了纤维混杂模式(随机混杂与包覆混杂)对混杂杆体静力、湿热老化与疲劳性能的影响规律.研究表明:挤压-摩擦型锚固系统受力均匀,锚固效率高,适用于混杂杆体的力学性能测试; 在一定的碳/玻璃纤维混杂比(2:3)条件下,通过将碳纤维束随机分散到玻璃纤维束中制备的杆体可以避免包覆混杂杆体中的GFRP皮-CFRP芯界面薄弱层脱粘破坏,短梁剪切、拉伸与疲劳性能得到显著提升,实现了正混杂效应; 在80 ℃高温浸泡下,随机混杂杆体受到碳-玻璃纤维/树脂界面劣化的影响,其界面强度保留率低于包覆混杂杆体.
Abstract:
Carbon and glass fiber hybrid reinforced polymer composites can play the advantages of high strength, high modulus, fatigue resistance of carbon fiber and high strain and low cost of glass fiber to meet the application requirements of engineering structure. In this paper, an efficient extruded-friction anchorage system was developed for mechanical tests of carbon-glass fiber hybrid reinforced epoxy resin composite pultruded rod, and the effects of fiber hybrid mode(random hybrid and coating hybrid)on mechanical, hygrothermal aging and fatigue properties of the hybrid rod were studied. Results show that the extruded-friction anchorage system had uniform stress distribution and high anchorage efficiency, which was suitable for the mechanical test of hybrid rod. At a certain carbon/glass fiber hybrid ratio(2:3), the rod prepared by randomly dispersing carbon fiber bundle into glass fiber bundle could avoid the debonding failure of the weak layer at the interface between GFRP skin and CFRP core of coating hybrid rod, which could greatly improve the short beam shear, tensile and fatigue properties and realize positive hybrid effect. Owing to the deterioration of the carbon-glass fiber/resin interface at the elevated immersion temperature of 80 ℃, the interface strength retention rate of random hybrid rod was lower than that of coating hybrid rod.
