摘要：
Composite sandwich structures were manufactured from a 3D woven fabric consisting of two face fabrics interconnected by pile yarns (Distance Fabric). Specimens were produced from Distance Fabric (DF) consolidated with vinyl ester resin with and without a polyurethane foam core and compared to specimens produced from a precast polyurethane foam core with composite skins added separately. Flatwise compression, edgewise compression, climbing drum peel and flexure tests were conducted and all demonstrated a dramatic improvement in properties from the combination of DF and foam core. These improvements are postulated to arise from the mutual reinforcement of the pile yarns and foam core. (C) 2000 Elsevier Science Ltd. All rights reserved.
