| Research Abstract |
We have proposed two methods to improve structural reliability of brittle materials. One of them is a simple evaluation of strength distribution using a simulations loading of many test pieces. The other is to establish a wise material with self-diagnosis function. Concerning the latter, concept, we have developed carbon-fiber-glass-fiber-reinforced plastic composite (CFGFRP), in which fatal fracture can be foreseen by monitoring the electrical resistance during and after straining. The resistance change of this composite is statistically interpreted using the fracture mode in a simultaneous loading system. The resistance change of the CFGFRP is found to be statistically reliable and reproductive.
