Static and Fatigue Interlaminar Tensile Characterization of Laminated Composites

摘要

Spool and curved-beam specimens were evaluated to determine the viability of using either one or both of these configurations to characterize the static and fatigue interlaminar tensile behavior of carbon/epoxy laminates. Unidirectional curved-beam and quasi-isotropic spool specimens were fabricated. nondestructively inspected, and statically tested to failure. Tension-tension fatigue tests were conducted at 10 Hz and an R-ratio (sigma_min/sigma_max) equal to 0.1 for each specimen condiguration. The interlaminar tensile strength of the spool specimen was 12
