Abstract
|
Adhesion in filled polymeric composites is characterized by an acoustic technique in which specimens of the composites are subjected to a ramped uni-axial tensile stress while particle-matrix debonding events are detected acoustically The maximum in a fitted distribution of debonding events as a function of applied stress is related to the interfacial strength using elasticity theory. Results are reported for different silane-treated and untreated glass and aluminum spheres embedded in a poly(vinyl butyral) matrix. Silane treatment profoundly affects the adhesive strength, with the strongest bonds being formed when acid-base interactions between the particle surface and the matrix polymer are promoted. Significant differences are also found between the aluminum-particle and glass-particle cases, attributable in part to differences in mechanical interlocking.
