| Popis: |
The microbond pullout technique for the measurement of interfacial shear strength in fiber-reinforced composites has provided data to support the hypothesis that observed bond strength variations for a fiber/resin system are mainly the consequence of fiber surface heterogeneities. This conclusion is based upon two observations. First, there is closer agreement in bond strength associated with near-neighbor fiber sites than for more widely separated sites. Second, shear strength distributions become narrower as embedment areas are increased. Since fiber surface defects and variations tend to average out when larger embedment areas are used, broad shear strength distributions may not be observed with macro pullout experiments. |
