一般复合材料系统是由基质(指结合料——译者)相和纤维相组成。这种复合材料的性能和破坏方式是由基质和纤维的相对硬度决定,也是由纤维的几何形状以及纤维、基质间的界面粘结强度决定。为了比较纤维混凝土和素混凝土的直接抗拉强度、间接抗拉强度和挠曲抗拉强度,进行了一些试验,从而得知纤维混凝土的上述三种强度都有大量增加。素混凝土只有很低的抗拉强度、有限的韧性和很小的抵抗开裂的能力。存在于混凝土内 The general composite system is composed of a matrix (binder) phase and a fiber phase. The performance and failure mode of this composite material is determined by the relative hardness of the matrix and the fiber, as well as by the geometry of the fiber and the interfacial bonding strength between the fiber and the matrix. In order to compare the direct tensile strength, indirect tensile strength and flexural tensile strength of fiber-reinforced concrete and plain concrete, some experiments were carried out to find out that there was a large increase in the above three strengths of the fiber concrete. Plain concrete has only low tensile strength, limited toughness, and a small resistance to cracking. Exist in concrete
