Before discussing these features, however, it is useful would be predicted from their separate effects. devitrification A high-temperature to consider the mechanics of fiber strengthening in composites. certain oxide glasses to convert the st coulombic force Name given to the electrostatic force 14.3.1 Strengthening by Fiber Reinforcement crystalline ceramics. that develops between charged species.
