چکیده
The present investigation was conducted on the low-speed impact response of quasi-isotropic [±45/0/90°]xs hybrid composite through laboratory level experimental tests. purpose to understand behaviour that different stacking sequences glass/carbon fibre composites has ability material sustain loads during events without developing critical structural failure in and improving energy absorption properties, which is a relevant matter aerospace automotive industries. Drop-weight tests were carried out two laminates, with sequences, each 16 symmetric inter-ply laminates named GC [+45G/?45C/0G/90C]4s and, respectively, G-C [+45G/?45G/0G/90G/+45C/?45C/0C/90C]2s, where G stands for glass C carbon fibre. Both comprised epoxy matrix reinforced carbon/E-glass woven fabric composites. outcome changing sequence, performances, discussed. damage morphologies local mechanisms analysed using visual inspection high-resolution laser scanner. Under 33 J energy, both tested exhibited approximately 10 kN peak load. Nevertheless, one key parameter, time load, significantly changed; initiation threshold samples occurred immediately before 6 kN, whereas this appeared much earlier. This type partly connected delay propagation delamination breakage, influenced by high elastic fibres when compared fibres. absorbed higher configuration, DI observed indicating percentage total dissipated in-plane out-of-plane fibre/matrix cracks. No perforation either configuration; nevertheless, area changed size appearance from configuration another.

Impact Damage in Woven Fabric Reinforced Composites
INTRODUCTION Very often, woven fabrics are used as the reinforcement in advanced composite materials. Although the resulting inplane stiffness is lower than of their unidirectional counterparts, the excellent drapability of these materials eases the production of more general doubly curved components. In addition, the inherently low out-of-plane strength of these layered materials improves due ...
