Influence of environmental factors on the mechanical properties of composites

Carbon/epoxy composites were studied in this paper. In order to find the most important factors which could destroy the performance of the composite materials, corrosion tests were carried out by means of immersion. The test conditions were decided by the orthogonal tests of three factors i. e. temperature, concentration and the test period. The results showed that the immersion deteriorated the properties of composites, as well as that the solution temperature was the most important factor among the three factors.
