摘要
Abstract
The drop -weight impact tests were conducted on cylinder carbon fiber composite over -wrapped vessel.Three axial locations on barrel of vessel were test with energy of 10,15,20,25,30 J. Comparative study of ultrasonic detection before and after impact,the curve of impact energy and depth of impact pit,inspection results with endoscope and of splited vessel,analysis of some parts with the thermal deply technique were discussed.The test results indicate that surface layers of composite were stratified af-ter impact,in the low energy condition,the depth of impact pit increases when impact energy grows.The impact resistance ability of middle part of composite vessel barrel is better that of connector of barrel and end socket.Whether the inner of composite is damaged cannot be distinguished from damage of surface layers.关键词
