摘要

This study focused on mechanical interpretation of the behavior of the stitched CFRP laminates under through-the-thickness tension loads. Tension tests in this direction for stitched CFRP laminates were carried out using the test specimens with a single stitch thread. The used KevlarR thread thickness were 400,600,800 and 1200 denier and the lock stitch by an industrial sewing machine was employed for the present laminates. The test specimens were glued to aluminum T angles and loaded by a screw driven test machine in the displacement control mode. Load-displacement curves were obtained for all the cases.
