摘要: Abstract An experimental investigation to optimize the absorbed energy of axially crushed composite collapsible tubular absorber devices was carried out. Different fiber orientation were used in this study (0/90, 15/−75, 30/−60, 45/−45, 60/−30 and 75/−15). The cost effective wet wrapping process fabricate specimens. quasi-static crush test performed under ambient conditions. results showed advantage laying woven 15°/−75° 75°/−15°, terms pre-crushing loading capacity absorbed. In addition, by means visual optical microscopy observations, failure modes all specimens discussed categorized.
