Summary:Hussain et al examine the potential to use oil found in soya beans, soyol based polyurethane foams (PUF) in Structural Insulated Panels (SIPS), motivated by their environmentally friendly, lightweight and cost-effective properties. In order for these materials to be effective as the core material for a SIP, they must have sufficient stiffness to resist buckling and localized skin wrinkling effects. For these reasons, current standards [1] suggest that the PUF core must have excellent stiffness under compression. One technique to improve the stiffness of polymers without significantly increasing the weight or cost has been to introduce fibers as reinforcement. Tthe use of glass fibers in PUF to improve the compressive and shear moduli is also examined.
