    Abstract

    The concepts of equilibrium free surface energies are presented and discussed in reference to the interfaces occurring between glass fibers, coupling agent, and resin matrix. Data from which the nature of the film of coupling agent on the fibers can be elucidated are presented. The conditions under which silanols and hydrolyzable silanes react with glass surfaces are given. Evidence is presented for chemical bonding between the hydrolyzate of γ-(methacryloxypropyl)trimethoxysilane on glass and a polyester.

    Keywords:

    composites, interfacial free energies, wetting, contact angle, surface tension, coupling agent, silane, adhesion, adsorption, radioactive tracers, glass, surfaces, polymers, interfaces, polyesters, evaluation, tests
