Presents the investigation of the failure behavior of filament wound cylindrical shells with glass/epoxy and glass/polyester. Through the experiment work on axially compressed composite shells with different reinforcing fiber patters, failure modes, load displacement relation, energy absorbing mechanism and effect of material and structural factors and concludes from test results that the better attenuation and higher energy absorption capability exhibit only in the progressive crushing shells, and for the [±θ] 5 glass/epoxy shells, the specific energy increases with the increase of winding angles; In the case of the axial impact tests, the crushing process and failure modes of glass/epoxy shells are the same as those of quasi static compression, and in addition, the specific energy of the shells, when θ45 °, has higher specific energy.
