Research and Innovative Technology AdministrationUS Transportation CollectionFiber Reinforced Polymer (FRP) composites offer inherent advantages over traditional materials with regard to high strength-to-weight ratio, design flexibility, corrosion resistance, low maintenance, and extended service life. FRP materials can be used to replacetraditional building materials like steel and wood. The application of composite materials will reduce cost and improve durability. One of the major cost drivers for composites is raw materials. Use of soybean-derived materials offers low cost raw materials.Development and performance evaluation of pultruded soy-based polyurethane composite panels is the focus of the proposedSoy-based polyurethane (PU) resin offers several benefits such as improved properties, faster production, and reduced VOCemissions. Missouri University of Science and Technology (MST) is collaborating with United Soybean Board (USB) to develop soy-based PU pultruded products for affordable housing and other commercial applications. Solid and core-filled pultruded parts will bemanufactured at MST and the performance of these products will be evaluated. Based on the test results, the resin chemistry will bemodified to achieve improved structural performance and also to incorporate more soy content in the formulation without property degradation
