To extend the service life of the equipment, a novel, efficient and cost-effective method is used to recover the damaged component of the equipment. The mechanical properties of unidirectional M40J/epoxy composites, prepared by molding process, were studied. Then the centre-cracked thick LC52CS aluminum plates were single and double side repaired with the composites patches by vacuum bagging technology in which three cure cycles were applied. Results show that a low cure temperature induce a small thermal residual stress. Choosing the cure cycle with the highest tensile strength of single-side repaired specimens, the tensile strength of single-side and double-side repaired specimens enhance 31.50% and 47.29% of that of the unrepaired specimens, respectively. And fatigue life of the double-side repaired specimens extends that of the cracked aluminum plate over 76 times, which is also significantly better than that of the single-side repaired specimen. |
