er com posites, similarly, have two (apparently) insurmountable obstacles to per formance: 1) Water can hydrolyze any conceivable bond between organic and inorganic phase, and 2) Stresses across the interface during temperature cycling (resulting from a mismatch in thermal expansion coefficients)

General Concepts,new bonding techniques arose in 1940 when glass fibers were first used as reinforcement in organic resins. The specific strength-to-weight ratios of early glass-resin composites were higher than those of aluminum or steel, but they lost much of their strength during prolonged exposure to moisture. T

Chemistry of Silane Coupling Agents,mpounds of the structure X.SiRY. The organofunctional groups (Y) are chosen for reactivity or compatibility with the polymer while the hydrolyzable groups (X) are merely intermediates in formation of silanol groups for bonding to mineral surfaces.

Aqueous Solutions of Silane Coupling Agents,nd their reactions with water and in water. Commercial practice is to apply silane coupling agents to glass from aqueous solutions of the alkoxysilanes. Organofunctional trialkoxysilanes hydrolyze in water and then condense to oligomeric siloxanols as described in Section 2.3.3. Stability and reacti

Surface Chemistry of Silanes at the Interface,s sufficient to provide marked improvements in composite properties. The small amounts involved, and the fact that silanes are buried in the matrix resin during fabrication, makes it very difficult to study the nature of the coupling action by ordinary chemical analysis. Prototype chemical reactions
