LOW-VELOCITY IMPACT PERFORMANCE OF OUT OF AUTOCLAVE PREPREG SYSTEM T700SC/#2510

Abstract

Abstract: The document tested the low-velocity impact performances (damage resistance and damage tolerance) of an Out of Autoclave (OOA) prepreg composite systems T700SC/#2510. The relationship curves between dent depth and impact energy per thickness millimeter (d-e), damage area and impact energy per thickness millimeter (S-e), compression strength after impact and notch depth (σ-d) are obtained with three kinds of classic layup. And the compression strength after impact with 6.7J/mm energy of three batches of this OOA prepreg quasi-isotropic laminates is also obtained. The results show that, the damage on the impact surface of the composite systems T700SC/#2510 is barely visible, but the internal damage area is very big. There is an inflexion in all the relationship curves of d-e, S-e and σ-d. The quasi-isotropic layup can absorb more impact energy, but results in a larger delaminating damage area. The CAI strength of this OOA prepreg quasi-isotropic has approached the target of the second generation OOA prepreg.

Key words: out of autoclave (OOA) prepreg, carbon fiber/epoxy, low-velocity impact performance, compression after impact
