碳纤维(CF)就性能而言,可以说是盖冠群伦了。但是,它的断裂伸张小,属于脆性材料。因此,单独使用时很难发挥其特性,往往需要和基体树脂相粘结,构成举世瞩目的碳纤维增强塑料(CFRP)。当CFRP承受抗压负荷时,应变较大的基体树脂发生形变,在纤维与树脂界面间产生剪切力;通过树脂的形变和间面的剪切把应力传递给纤维,使其受到轴向拉应力,充分发挥了纤维的高强度的特性。欲达 Carbon fiber (CF) in terms of performance, it can be said is crowned crowds. However, its elongation is small, are brittle materials. Therefore, when used alone it is difficult to play its characteristics, often need to bond with the matrix resin to form a world-renowned carbon fiber reinforced plastics (CFRP). When the CFRP under compressive load, the larger strain of the matrix resin deformation occurs in the interface between the fiber and the resin shear force; by resin deformation and inter-face shear stress transfer to the fiber to be axially pulled Stress, give full play to the high strength of the fiber properties.
