摘要
对比研究了空心玻璃纤维与实心玻璃纤维单丝及复丝拉伸强度,建立了玻璃纤维单丝强度模型。通过缠绕工艺及模压工艺制备了空心/实心玻璃纤维复合材料(HGFRP/SGFRP)单向板,考察了HGFRP及SGFRP单向板的拉伸性能及弯曲性能。研究表明,空心玻璃纤维及实心玻璃纤维单丝拉伸强度均符合Weibull分布,空心玻璃纤维单丝及复丝的拉伸强度低于实心玻璃纤维,HGFRP的比拉伸强度和比弯曲强度略低于SGFRP,但HGFRP的比拉伸模量和比弯曲模量高于SGFRP。研究表明,空心玻璃纤维有望在新一代轻质高强材料中发挥新型异型纤维增强体的作用。
To study the properties of hollow glass fiber and its composite,in this work,filament and multifilament tensile strength of hollow glass fibers and solid glass fibers were compared and a glass fiber filament strength model was established. Furthermore,hollow / solid glass fiber reinforced polymers( HGFRP / SGFRP) were fabricated by winding process and molding process,and tensile property and bending property of these two composites were tested.The result indicates that the filament tensile strength of hollow / solid glass fiber coincides well with the Weibull distribution model. Tensile strength and bending strength of hollow glass fibers are lower than that of solid glass fibers. It also shows that the specific tensile / bending strength of HGFRP is less than that of SGFRP. However,the specific tensile modulus and the specific bending modulus of HGFRP are higher than that of SGFRP. Consequently,it can be deduced that hollow glass fibers can be served as a promising reinforcement for the next-generation light-weight composites.
