A LOW COST INTERPHASE CHEMISTRY TO PROMOTE CARBON FIBER-VINYL

Triton Systems, Inc. proposes to demonstrate a low cost interphase chemistry which will improve the mechanical strength of carbon fiber/vinyl ester composites by providing a polymer layer which bonds exceptionally well to both the carbon fibers and the vinyl ester resin. This interphase chemistry will utilize a Triton proprietary polymer applied to the carbon fiber surface and adhered to the surface through strong hydrogen bonding. The surface of the carbon fiber will be preoxidized to improve bonding to the polymer. This proprietary interphase polymer has also been shown to be miscible with vinyl ester resin, forming a single phase between the two polymers rather than a distinct, and structurally weaker, two phase blend. The polymer chemistry will be optimized for compatibility with vinyl ester resins using Triton System¿s vast experience and database with these materials. In the Phase I program we will demonstrate the improved fiber/matrix adhesion via transverse tensile testing of unidirectional composites. In a Phase II program we will scale the process up to pilot production levels and demonstrate the technology on a large scale Naval component.
