Delamination resistant composites by interleaving bio-based long-chain polyamide nanofibers through optimal control of fiber diameter and fiber morphology [PDF]

open access: yes, 2020
In this work an innovative electrospinning system is proposed that simultaneously has an adequate temperature resistance, a high increase in mode I (þ51%) and mode II (þ96%) delamination performance and can be commercially produced.

Fracture Behaviors of CFRP Laminates in Mode I Interlaminar Fracture Toughness Testing.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1997
Fracture behaviours in mode I delamination tests of CFRP(T300/2500)were studied at cross-head velocity V=0.005∼200 mm/min. In low velocity region, serrations due to repeated unstable fracture appear on load P-displacement δ curve, and they become conspicuous as V becomes smaller.
