| Abstract: | On the basis of analysis and overview of the defects or damage types, repair methods, required equipment and materials as well as its processing for typical honeycomb sandwich structures, more emphases are given on the studies of filling repair process in this paper. It is shown that suitable repair material such as G7A-20 can be with a good operation and can be cured at RT,with a density of no more than 0.8 g/cm3 and tensile strength of more than 3.4 MPa, and as a result more than 80% of design allowable values of compress strength and modulus can be obtained. |
