| Abstract: | Several cracks developed at the edge of an aircraft side windows PMMA(polymethyl methacrylate).The cause of the cracks was analyzed by observation of the cracks distribution and macromorphology,macroscopical and microcosmic examination of the crack fracture,FTIR analysis of the matrix and the surface tan belt areas of the side window PMMA,and conduction of the stress-corrosion test of the side window PMMA.The results showed that the mechanism of the cracks were stress-corrosion cracks,which were mainly induced by corrosion effect of FN-303 chloroprene rubber adhesive. |
