The weaved fiber I have is plain weaved bi-directional natural fiber. I need find its tensile strength. The ASTM standard D3039 applicable to PMCs is not applicable to weaved fibers, fiber mats, etc. D5587 − 15 trapezoidal method of determining tear strength applies to most fabrics including woven fabrics, air bag fabrics, blankets, napped fabrics, knitted fabrics, layered fabrics, pile, and nonwoven fabrics. Am I technically correct in using this standard ? Have anyone used this standard before ? Please share your experience.
