Properties of Polyester Resins for Fiberglass Reinforced Soil Surfacings.

摘要

A Marine Corps chemical formulation developed for the construction of fiberglass reinforced plastic soil surfacings consists of a polyester resin, a catalyst, and a promoter solution. The baseline properties of the currently used polyester resin, a sole source item, were measured. Two other resins were then obtained for evaluation as possible alternates to the original resin. Even though there are significant chemical differences, both resins appear to be acceptable for this application. One resin has somewhat longer gel times than desired, but this could possibly be remedied by lowering the inhibitor content slightly. Preparation of test pads would be the next step in the resin evaluation. (Author)
