Espinoza Perez North Dakota State University Future Work • Seek funding/cooperaon opportunies • Test natural grade fibers, fiber loading levels and the effect of surface treatments • Conduct detailed composite property tests • Study effect of various synthec acrylates in the resin Biocomposites are composed of a biorenewable resin reinforced with natural fibers. These promising materials have the potenal to be used everywhere, from the automove industry to drug delivery in human bone graﬅing, and normally are thermally cured. This ultraviolet (UV)-cured approach reduces producon mes, eliminates solvent emission and allows for a completely “green” manufacturing process and final product. What is “Green Chemistry”? Green chemistry aims to create sustainable and health-conscious soluons for today’s ever-increasing technological needs. Green chemists develop solvent- free and renewable products that are less hazardous to human health and the environment. Since energy consumpon is a global concern, green chemists also focus on processes that use less energy than convenonal means. Materials These biocomposites are composed of two kinds of vegetable oils (A and B, which are chemically modified to improve UV curability) and natural plant fibers. The whole curing process using the UV lamp takes one minute! Conclusions Incorporang natural fibers into UV-curable vegetable oil-based resins improves the strength of the resin by a huge percentage. The addion of a small amount of synthec resin can improve these properes even further, but the effecveness of a completely biorenewable system can be seen while maintaining a high biorenewable content. Benefits • Biodegradable and biorenewable: natural materials with 75% to 95% biorenewable content • Environmentally friendly: no solvents released into the environment • Totally “green”: green chemistry and green curing technology • No thermal consumpon: uses the power of light • Increased manufacturing speed = increased producvity • Lower manufacturing cost: cheaper than synthecs such as fiberglass
