The indiscriminate use of wood has led to a serious environmental and ecological crises and rapid depletion of forest cover. Therefore, there is an urgent need to develop suitable substitutes to wood-based building products. A great deal of research and development has gone into composites. The introduction of FRP (Fiber Reinforced Polymer) with their superior properties in the complex application in Aerospace, Shipping, and Automobile industries paved the way for the development of sandwich FRP doors, with their advantage of superior properties at competitive price.
