EXPERIMENTAL RESEARCH ON FATIGUE LIFE OF BONDED COMPOSITE REPAIRS TO DAMAGED METALLIC STRUCTURE UNDER COMPOUND ENVIRONMENT

Abstract

Abstract: Bonded composite repairs have been successfully applied to damaged aircraft structure. The repaired structure is still influenced by compound environment factors during service life of the aircraft. In order to evaluate the influence of environment factors to repair structure, carbon composite patches are double adhesively bonded to center-cracked LY12-CZ plate. The rationality of this repair method was evaluated by experiment, and the fatigue life under compound environment factors was examined by t-test method.

Key words: bonded composite repair, aluminum alloy, environment experiment, fatigue test, t-test method

CLC Number:
