More Information
Summary:A composite material consisting of carbon fiber fabric and polyurethane resin was used to fabricate circular tubes by resin transfer molding. The composite tubes were tested under both axial static compression and axial impact. To establish delamination criterion for this composite material, short-beam tests and curved-beam tests were executed, and it was verified by step cantilever-beam tests. The short-beam and curved-beam tests indicate that the interlaminar shear and tensile strengths of the composite are around 54.0 MPa and 8.8 MPa, respectively. Also the established delamination criterion has nice prediction for the delamination of the step cantilever-beam test. In addition to the delamination criterion, the finite element analysis with progressive failure was applied and could predict agreeable values on the total absorbed energy and the specific energy absorption of the braided composite tube under both the static and dynamic tests. These indicate that the present analysis could catch the axial crushing behavior of the braided composite tubes.
