一般注記A brittle lacquer mapping technique was used to check the strength of the jointed part of a composite F.W. cylinder. The test was done by using the following steps; 1)By using the results from the analysis and the bending test of specimens made from the same kind of composite F.W. cylinder, the brittle lacquer map of fracture and the map on the location of sufficient strength in the specimen were found. 2)Comparing these two maps with the brittle lacquer mapping on the test structure, a search was made to find fractures, cracks around holes and stress concentrated areas of the test structure, especially its jointed part. The test structure, NAL-7P one stage rocket, was bent by the 15G load applied in the center of its joint. There were not any fractures or cracks in the test structure, but a few stress concentrated and hoop stressed areas were found.
