Abstract
The article presents the effect of dimensions and geometry on the crushing behavior, energy absorption, failure mechanism, and failure mode of woven roving glass fiber/epoxy laminated composite tube. Three sizes (big CCT1, medium CCT2, and small CCT3) of cylindrical composite tubes (CCT) were fabricated and tested under the same conditions. Comprehensive experimental work was conducted that includes axial and lateral quasi-static crushing test to examine the influence of the design parameters on the energy absorption characteristics of CCT. Load–displacement curves and deformation histories were presented and discussed. Different parameters were obtained from studying of load–displacement curves, these parameters are: initial failure load, average crushing load, and total energy absorption. For axial load, the results showed that among the three tested specimens, CCT3 records the highest initial crushing load of 41.788kN, followed by CCT2 of 29.146kN. However, CCT1 recorded the lowest initial crushing load of 26.513kN. In addition to that, for lateral crushing, results showed that CCT3 gave the best result among others.
