Fiber fractures will occur at these flaws at more or less random positions throughout the composite. Therefore, fracture will not occur in a single plane. In the simplest case, in which the imperfect fibers all have the same strength and the matrix is unable to grip the broken fibers, the strength of the composite would be calculated as in the previous subsection. For brittle fibers, however, flaws vary not only in position, but also in severity. 9 for a typical case. Therefore, it would be expected that fiber fractures would occur throughout a range of stress levels, up to ultimate composite failure.
As mentioned earlier, most advanced composite structures are made of laminates in the form of unidirectional plies laminated together at various orientations. The fracture behavior of these materials is considered in Chapter 6 and 8. In laminates, toughness is highly dependent on the degree of ply splitting and inter-ply disbonding (delamination), resulting in high-energy absorption and crack deflection. An approach similar to that just described can be taken for this highly complex situation. 16 The direction of crack growth is based on the R1/R2 ratio for each ply and the G1/G2 ratio for the laminate.
For the epoxy resin am ----55 x l0 --60 C- - 1 However, this model does not account for any interaction between the fiber and matrix, due in part to ignoring differences in Poisson's ratio, and leads to the conclusion that there are no thermally induced stresses between the fiber and matrix. 1 Simple Estimate of Tensile Strength The simplest analysis of longitudinal tensile strength assumes that all fibers break at the same stress level, at the same time, and in the same plane. Although this assumption is grossly unrealistic, it provides a useful starting point for more realistic analysis.
