Influence of Matrix Modification on the Solid Particle Erosion of Glass/Epoxy Composites

Abstract

Solid particle erosion of glass fibre-epoxy composites with the matrix modified by incorporating either carbon black filler or a rubber material known to enhance toughness has been studied, together with a case where both materials are simultaneously included in the resinous matrix. How the semiductile behaviour of the thermoset matrix is affected by the matrix modification formed the primary objective of this work. The erosion weight loss was studied with respect to the angle of impingement. Eroded surfaces of test samples were examined under SEM to observe fracture features. For a matrix containing carbon, the angle for peak erosion remained at 45° despite variations in filler content. But in the case of a rubber toughened matrix, a shift of this angle to 30° is noticed suggesting a change in the mechanism of material removal. When carbon filler was added to the rubber-toughened matrix, it appeared to influence the erosion behaviour.

“…Solid particle erosion is the progressive loss of original material from a solid surface due to mechanical interaction between the surface and impinging particles. Various applications of polymers and their composites in erosive wear situations are reported by Pool et al [5], Kulkarni et al [6] and Aglan and Chenock [7] in the literature. But solid particle erosion of polymers and their composites has not been investigated to the same extent as for metals or ceramics.…”

“…These papers mainly showed, however, only the erosion behavior and the performances to erosive damage [12][13][14][15][16][17][18][19][20][21][22]. Although various types of fibre are used for reinforcing plastics, no paper has been published in which the effect of types of fibre, e.g.…”
