Abstract

Axial tensile modulus, compressive modulus and compressive strength of poly(p-phenylene benzobisoxazole) fiber were measured with a Tecam Micro-tensile Testing Machine. This machine was configured to allow direct tension and compression testing of a single fiber at extremely small gauge length. The measured tensile and compressive moduli were analyzed for machine compliance corrections and possible gauge length error. Results were discussed for the effects of non-uniform stress distribution and fiber misalignment. By comparing the axial compressive strengths measured from various single fiber characterization techniques, direct compression furnished data closer to that measured from composite compressive tests.
