Braided and filament-wound tubular composites were produced by various glass fiber preform structures on a cylindrical mandrel using a modified maypole braiding machine. The composites were then impregnated with unsaturated polyester resin by vacuum infusion process (VIP). After performing compression test on the samples and calculating the failure force and failure energy, it was observed that the filament-wound sample displayed higher compression properties than those of braided samples with the same fiber volume percent. This was due to having more reinforcing layers with more reinforcing strands for compensating the effect of waviness in its braided counterpart. The results showed that the braided samples, with the same number of layers with the filament-wound tubes but different fiber volume percentage, show the highest compression failure force and energy. The reason for this phenomenon was attributed to higher tube wall thickness in the braided sample and consequently more stable behavior during compression loading.
