基于锚固系统下碳纤维板松弛性能的研究

Study on Relaxation Performance of Carbon Fiber Plate Based on Anchor System

摘要: 碳纤维增强聚合物(CFRP)片材作为近些年热门的复合材料，除开在结构工程领域常起的加固作用，使用这种材料的拉索在斜拉桥与悬索类的桥梁结构中与传统的钢索相比具有优异的材料性能，故碳纤维拉索凭借着自身价格低，工程性价比高的优势在桥梁领域名声大震，成为未来传统钢索的潜在主力替代品。本文主要根据试验研究基于锚固系统下的碳纤维复合板材的松弛性能。总结了CFRP片材蠕变力学模型和蠕变量时间曲线。

Abstract: As a popular composite material in recent years, carbon fiber reinforced polymer (CFRP) sheet, apart from its reinforcement role in structural engineering, has excellent material properties compared with traditional steel cables in cable-stayed bridges and suspension bridges. Therefore, carbon fiber cables are famous in bridge field because of their low price and high engineering cost performance, and become the potential main substitute of traditional steel cables in the future. In this paper, the relaxation performance of carbon fiber composite plates based on anchorage system is mainly studied. The creep mechanical model and creep characteristics of CFRP sheets are summarized.
