Abstract

Epoxy compatible P(St-co-GMA) copolymer based nanofibrous mats are introduced by electrospinning onto uni-directional (UD) and 0/90 twill weave carbon fiber/epoxy prepreg systems as interlayers. Anticipated in-plane strength improvement via higher matrix cracking resistance at the free edges, nanofibrous interlayered composites are verified by uni-axial tension tests on (0)₆ and (0/90)_6woven laminates. The ultimate tensile strength of the (0)₆ laminates increased by 12%, whereas the tensile strength of the woven fabric composites increased by 18%. A localized interlayer reinforcing approach where the interlayers are incorporated at the vicinity of the hole is evaluated via open hole tension (OHT) tests of (0/90) _6woven laminates. The OHT strength increased by 9%.
