INVESTIGATION OF THE PHYSICAL-CHEMICAL NATURE OF THE MATRIX-REINFORCEMENT INTERFACE.
Abstract
It was the intent of the investigation to initiate a study of those chemical phenomena which occur at the interfaces between glass and silane coupling agent and between coupling agent and resin matrix. From the data obtained on the adsorption of mono-functional silanes, it was possible to infer which reactions had occurred at the interface between coupling agent and glass. Heats of immersion of the glass in water have also been measured to determine the forces of interaction between the glass and water. The techniques which so far have yielded the most information capable of interpretation have been adsorption-desorption measurements, electron microscopic examination of treated surfaces, and isothermal heats of wetting. From the data obtained to date it is concluded that there is a very limited chemical reaction occurring between glass and coupling agent; most of the interaction at the glass interface is very weak. Conceivably the amount of reaction will be influenced by the method used to apply coupling agents to the glass surface. (Author)
