Article Preview

The effect of curing pressure, curing temperature and curing time on the mechanical properties of the adhesively bonded composite structure of CFRP and Al are studied by means of the Orthogonal Test. Indexed by the fatigue life of the composite structure of CFRP and Al in room temperature environment and by making the direct, variance and effect analysis for the test data, we have obtained the optimal curing technology scheme within the test range. Because the optimal scheme isn’t included in the orthogonal table, we make the point estimation in order to get the fatigue life corresponding to this scheme. At last, the fatigue life under the optimal scheme is obtained by adding a test, the result of which is consistent with that of the theoretical analysis.The effect of curing pressure, curing temperature and curing time on the mechanical properties of the adhesively bonded composite structure of CFRP and Al are studied by means of the Orthogonal Test.
