Abstract:
Experiments were designed to develop evidence for or against the theory that appropriate chemical functional groups in finishes constitute reactive sites for chemical bonding between a laminating resin and the finish during cure. Data show that it is possible, on the basis of the theory, to design ineffective as well as effective finishes. The strengths from laminates made with NOL-24 finished glass fabric were 64 to 600 greater than those from laminates made with dimethyldichlorosilane. These data cited, as well as other outside data, constitute evidence of an indirect nature favoring the theory. The tensile strength of heat cleaned fabric in the warp direction was raised from 260 lb57 yarns to 370 lb57 yarns by the NOL-24 treatment. A new Preferential Adsorption Theory is proposed which can serve to explain how a finish functions at the glass resin interface. Author
