Effect of Variables on Surface Appearance of Fiberglass Reinforced Plastics 680060
Three surface characteristics: gloss, microinch finish (fiber pattern), and long term waviness, are discussed. Almost all variables have an effect on at least one of these characteristics. The main variables are molding temperature, cure time, glass type, glass content, filler type, filler content, resin, catalyst, surface mat, and post molded condition. The properties of the resin are most significant.
With proper selection of resin, filler, and glass, and using proper molding conditions, laminates with excellent surface appearance can be made.
