| heal.abstract | Solid particle erosion of epoxy resin (EP) modified by various amounts of hygrothermally decomposed polyester-urethane (HD-PUR) was studied at oblique (30, 45, and 600) and normal impact (90 degrees). The cross-linked structure of the modified EP was characterised by the mean molecular weight between cross-links (M-c). It was established that the initial brittle erosion of the densely cross-linked EPs (M-c less than or equal to 200 g/mol) changed to a rubbery one by increasing HD-PUR modification due to which a less cross-linked network was formed (Mc > 1000 g/mol). This change was reflected by the impact angle dependence: compositions of low M-c showed the minimum resistance at normal (90 degrees), whereas those of high M-c at 30 degrees impact angle. The resistance to solid particle erosion changed linearly with increasing fracture energy (G(c)) of the resins. G(c), on the other hand, followed the prediction of the rubber elasticity theory and increased linearly with M-c(1/2). (C) 2001 Elsevier Science B.V. All rights reserved. | en |
