Effects of manufacturing and face/core bonding on impact damage in glass/polyester–PVC foam core sandwich panels

Effect of manufacturing on impact damage behaviour was investigated in typical marine composites of E-glass fibre/polyester/PVC foam core sandwich structures. Face/core bonding was performed using two different adhesives and the matrix resin. Low velocity impact response of the sandwich plates was investigated using an instrumented impact drop tower. Impact damage size was estimated by visual inspection or by the ultrasonic C-scan. Failure...
