“…Unlike the typical layer-to-layer structure, the fabric is modified by additional warp yarns interlaced into the top and bottom layers following a plain weave pattern to strengthen the whole structure. The details relating to the two types of performs are summarised in Table 1, and are further reported in [34]. It is worth noting that in both fabrics all the yarns are identical.…”

a b s t r a c tA detailed investigation of the failure mechanisms for angle-interlocked (AI) and modified layer-to-layer (MLL) three dimensional (3D) woven composites under tension-tension (T-T) fatigue loading has been conducted using surface optical microscopy, cross-sectional SEM imaging, and non-destructive X-ray computed tomography (CT). X-ray microCT has revealed how cracks including surface matrix cracks, transverse matrix cracks, fibre/matrix interfacial debonding or delamination develop, and has delineated the complex 3D morphology of these cracks in relation to fibre architecture. For both weaves examined, transverse cracks soon become uniformly distributed in the weft yarns. A higher crack density was found in the AI composite than the MLL composite. Transverse cracking initiates in the fibre rich regions of weft yarns rather than the resin rich regions. Delaminations in the failed MLL specimen were more extensive than the AI specimen. It is suggested that for the MLL composite that debonding between the binder yarns and surrounding material is the predominant damage mechanism.

“…This semi-discrete shell finite element is comprised of unit woven cells with rotation free, which presents only displacements of nodal variables. Angle-interlock structure has relatively straight weavers' yarns inclined at an angle to the warp direction (Potluri et al, 2012), and more elongation is permitted in the warp than in the weft direction. Compared to the 2D fabrics, the mechanical behaviour of 3D interlock fabrics is more difficult to describe.…”

a b s t r a c tThis study investigates the performance of three-dimensional (3-D) woven interlock composite plates subjected to impact loading. Low velocity (lower than 10 mÁs À1 ) impacts with highly deformable rubber impactor are addressed. Response variability is investigated by conducting several impact tests in the same conditions. The effect of mass and velocity on damage tolerance is studied by varying the impact conditions. Force-time, displacement-time and force-displacement curves are first analyzed in such various impact conditions. Secondly, damage mechanisms are highlighted through microscopic observations. The large geometrical deformation of the rubber impactor during impact leads to a loading less localized than for a hard impactor which induces a wide spread damage distribution. Comments on the relations between damage states and mass-velocity conditions are proposed.Crown
