Buckling analysis of two layer delaminated beams with bridging

Improvements in Mode I interlaminar fracture toughness and in-plane mechanical properties of stitched glass/polyester composites

“…Through thickness stitching is a promising reinforcing technique to improve interlaminar strength and delamination resistance [2][3][4][5]. The improvement in delamination resistance is primarily due to suppression of the delamination crack growth by stitches.…”

Buckling of composite beams with two enveloped delaminations: Lower and upper bounds

“…The gap between the upper and lower bounds of the buckling loads is higher for shorter enveloped delaminations. As the lower and upper bounds of the buckling load are the minimum and the maximum loads that a composite beam can with stand, these bounds can be useful to know the effect working range of the bridging [30] that will be a possible future work. Fig.…”

“…Analytical models to obtain lower and upper bounds of the buckling load of composite beams with two enveloped delaminations have not yet been reported. These two bounds will be useful to gauge the working range of the bridging [30] and give guidelines for practical applications [31]. The objective of this work is to present analytical models based on the Euler-Bernoulli beam theory to analyze the buckling of composite beams with two enveloping delaminations.…”

Simple stitch-assisted carbon fiber-aluminum laminates via out-of-autoclave process

“…[37][38][39][40][41] Through-thickness stitching is one of the promising techniques used to improve the interlaminar strength of the VARTM-produced FML around the holes. [42][43][44] This improvement is achieved by suppressing delamination growth through reinforcement in the thickness direction. 45 Once the metal layer is perforated prior to VARTM, not only resin flow but also through-thickness stitching can be applied along the holes.…”
