摘要

This works investigates the fabrication and mechanical properties of three-dimensional (3D) integrated fabric-reinforced composites, which were produced using a simple hand-lay technique with polyester resin impregnation. Two types of 3D integrated fabrics, with and without core, were constructed using a conventional stitching technique and used as reinforcing materials in the composites. Specimens of standardized size were tested to evaluate the tensile, compressive, and flexural properties of the composites. The results demonstrated that both the tensile strength and tensile modulus were greater in the vertical direction test compared to the horizontal direction for both types of composites. Regarding a compression test, the composite with a core showed higher compression stress values in both directions, except for the second peak in the horizontal direction test, where the coreless composite performed better. The compressive modulus of the composite with a core was higher than that of the coreless composite in the vertical direction test, but lower in the horizontal direction test at all measurement peaks. As for flexural properties, the flexural stress was similar for both composites, while the flexural modulus was higher for the composite with a core, indicating enhanced resistance to bending.
