Technical Abstract: Soybean oil/epoxy based composites are prepared by Solid Freeform Fabrication (SFF) methods. SFF methods build materials by the repetitive addition of thin layers. The mixture of epoxidized soybean oil and epoxy resin is modified with di, tri or polyethylene amine gelling agent to solidify the materials until curing occurs. The high strength and stiffness composites are formed through fiber reinforcement. E-glass, carbon and mineral fibers are used in the formulations. It was found that a combination of two types of fibers can be used to achieve higher strength and stiffness parts than that obtained from a single fiber type at the same conditions. In addition, the effects of curing temperature, curing time, fiber loading, and types of fibers on mechanical properties of composites are reported.
