摘要/Abstract

摘要： 本文通过设计11组碳/玻混杂纤维复合材料(HFRP)样条的拉伸对比实验,分析研究CF与GF的不同混杂比对复合材料拉伸性能的影响。结果表明,随着玻璃纤维中加入碳纤维相对体积分数的增大,其拉伸强度和模量也随之增大,断裂延伸率随之降低。通过理论计算,50m长风电叶片主梁帽采用碳/玻混杂复合材料比采用纯玻纤其重量可降低10%~60%,成本将提高150%~310%,而相对于整支叶片重量可降低4%~22%,相对于整机其整体成本相当甚至降低。

Abstract: In this paper, through 11 groups of tensile comparative experimental samples, the tensile properties of C/G hybrid fiber-reinforced composites at different hybrid ratios were analyzed. The results show that with the relative volume percentage of carbon fibers in the C/G hybrid fibers increasing, the tensile strength and modulus of the HFRP increased, and the elongations of the HFRP decreased. By means of theoretical calculations, the economical benefits of the spar cap for 50m long wind turbine blades made of C/G hybrid fiber-reinforced composites were calculated. If the C/G hybrid fiber-reinforced composites were used to made the spar cap, the weight of the spar cap can be reduced by 10%~60% compared with using glass fibers, and the cost of the spar cap will be increased by 150%~310%. However, relative to single wind turbine blade the weight of the blade can be reduced by 4%~22%, the cost of overall wind turbines will equal or even be decreased.

Key words: C/G hybrid fiber-reinforced composites, tensile properties, wind turbine blades, spar cap, weight reduction
