Summary:

To overcome the most serious deficiency in fiber-reinforced composite materials a three-dimensional, continuously woven material has been developed. To demonstrate the feasibility of the new weave pattern, a 0.3 in thick fabric was woven with 12-end S-glass roving and impregnated with Epon 828 epoxy resin using curing agent Z. A 24 harness semiautomatic loom was used to produce the fabric.Tension tests were conducted on the material in both the weave and transverse directions. The material exhibited maximum tensile strength of 47,000 psi and 64,000 psi in the weave and transverse directions, respectively. The elastic moduli were 2,640,000 and 3,220,000 psi, respectively.Compression tests were conducted in the weave (longitudinal), transverse, and thickness directions. The ultimate strengths in compression were 39,000, 52,000, and 71,000 psi, respectively. The elastic moduli in compression were 2,820,000, 3,410,000, and 1,240,000 psi in the three respective principal directions.The Poisson ratios were obtained for both tension and compression
