Method for alleviating thermal stress damage in laminates |
摘要 |
A method is provided for alleviating the stress damage in metallic matrix composites, such as laminated sheet or foil composites, wherein discontinuities are positively introduced into the interface between the layers so as to reduce the thermal stress produced by unequal expansion of the materials making up the composite. Although a plurality of discrete elements could be used to form one of the layers and thus carry out this purpose, the discontinuities are preferably produced by simply drilling holes in the metallic matrix layer or by forming grooves in a grid pattern in this layer.
