GLASS SURFACE CHEMISTRY FOR GLASS FIBER REINFORCED PLASTICS
Abstract
A test for measuring the glass-to-resin bond strength in a dry environment appeared capable of distinguishing changes in the glass surface chemistry. The test indicated that the coupling agent A-1100 slightly improved the bond strength. An attempt will be made to correlate optically flat and as- cast glass surfaces with respect to bond life, bond strength, and wetting. Bond life studies in 100% relative humidity showed this environment to be almost as severe as immersion in water. Optical polishing changes the glass surface both physically and chemically. The significance of differences between the optically polished and virgin as-cast glass surface has not been established. Studies using a sample having an optically flat glass surface instead of the slightly curved as-cast surface would be simpler, particularly when measuring bond strength.
