Title:
Sustainable, Green Vinyl Ester Resin (VER) from Renewable Resources
Report Date:
2017-04-02
Abstract:
Sustainable Green Vinyl Ester Resin (VER) from Renewable Resources Objective: Carbon-fiber reinforced composites of Vinyl Ester Resin (VER) are largely used in Department of Defense (DoD) weapons platforms. Critical composite structures for ship hulls and transportation vehicles can be made using a low-cost VER that can be processed at ambient temperature using vacuum-assisted resin transfer molding (VARTM). Current precursors for making VER are isolated from petroleum feedstock, which is subjected to fluctuating prices and limitations in supply. In addition, the synthetic route uses epichlorohydrin as one of the precursors, which is a potential carcinogen. The objective of this SERDP project was to develop a sustainable, environmentally safe VER for military structural composite weapons systems starting with low-cost lignin and glycerin biowaste streams, prepare various formulations and their carbon fiber reinforced composites that can completely or in part replace the current commercial resin manufactured from petroleum feedstock.
