Quasi-three-dimensional woven composites

The phenomenon of delamination hinders the unreserved use of composite materials in strategic applications especially those which might involve fatigue or impact loading. This thesis explores the effect of inter-laminar three-dimensional (Quasi-three-dimensional) fabric weaving on the structural, energy absorption and damage resistance properties of glass-epoxy composites in a low-velocity penetrative impact event, through experimental studies. Traditionally used laminated and two-dimensionally woven composites are used as references for comparison of performance. It was found that quasi-three-dimensional composites are viable alternatives to traditional composite systems where energy absorption or damage resistance is of greater importance.
