建立了单织碳纤维无屈曲织物（NCF）增强环氧聚合物机械性能的完整数据库。在正常载荷和剪切载荷下对单向层压板进行面内和全厚度测试。还测量了循环剪切载荷下的响应。该材料已根据不同载荷情况的刚度、强度和失效特征进行了表征。通过层间和跨层断裂韧性测试测量与材料中不同失效模式相关的临界能量释放率。包括拉伸、压缩和剪切测试样本的应力-应变数据。还包括所有断裂韧性测试的载荷-挠度数据。该数据库可用于开发和验证纤维增强塑料 (FRP) 的分析和数值模型，特别是具有 NCF 增强材料的 FRP。
A complete database of the mechanical properties of an epoxy polymer reinforced with uni-weave carbon fibre non-crimp fabric (NCF) is established. In-plane and through-the-thickness tests were performed on unidirectional laminates under normal loading and shear loading. The response under cyclic shear loading was also measured. The material has been characterised in terms of stiffness, strength, and failure features for the different loading cases. The critical energy release rates associated with different failure modes in the material were measured from interlaminar and translaminar fracture toughness tests. The stress–strain data of the tensile, compressive, and shear test specimens are included. The load–deflection data for all fracture toughness tests are also included. The database can be used in the development and validation of analytical and numerical models of fibre reinforced plastics (FRPs), in particular FRPs with NCF reinforcements.
