Abstract: The present invention pertains to bio-based block polymers synthesized from functionalized lignin-based molecules (A-monomer) and functionalized fatty acids or fatty alcohols (B-monomer) derived from plant or animal oils, waxes or fats. The block polymers can be synthesized via numerous polymerization techniques, such as reversible addition-fragmentation chain transfer (RAFT). Most importantly, this class of bio-based block polymers shows promise as providing sustainable yet scalable and tunable thermoplastic elastomers and pressure-sensitive adhesives, among other applications.

Abstract: This present invention is directed to the use of bio-based materials such as functionalized plant oils and natural fibers to provide substitutes for leather materials. The bio-based materials provide composites made with a range of natural fibers such as flax, cotton, jute and kenaf fibers, combined with natural plant oils (triglycerides) such as soy oil, linseed oil and their fatty acids. The natural fibers may be used in their as-delivered woven or nonwoven state and the triglycerides and fatty acids are chemically modified to allow them to react in a controlled manner giving predictable thermal and mechanical properties. The resulting material is a breathable, water resistant, leather-like material. This present invention is also directed to methods of making the substitutes for leather materials.

Abstract: A three dimensional composite panel structure is provided having a thickness less than about 22.5 cm, overall density less than 0.2 g/cm, and exhibiting a global modulus greater than 1.2 GPa and stiffness greater than 15 kN-m2. The composite panel structure includes at least two fiber-reinforced mats interconnected in a spaced substantially parallel configuration by a skeletal web and a closed cell foam filling the spaces between the panels. The fiber-reinforced mats include a plurality of fibers in a low viscosity cured thermosetting resin matrix.

Abstract: The synthesis of liquid molding resins derived from plant oils that are capable of curing to high modulus thermosetting polymers and composites is described in this invention. The resins described resemble the unsaturated polyester, vinyl ester and epoxy resins presently used as the polymer matrix material in high performance glass, carbon, aramid and natural fiber reinforced composite materials. The resins disclosed herein are suitable for polymer and composite manufacture by Resin Transfer Molding (RTM), Reaction Injection Molding (RIM), Vacuum Assisted Resin Transfer Molding (VARTM), Seeman's Composite Resin Infusion Manufacturing Process (SCRIMP), Atmospheric Pressure Molding (APM), open mold casting, spray-up, Sheet Molding Compound (SMC) Bulk Molding Compound (BMC), filament winding, pultrusion, prepregs, lamination and compression molding.
