Zusammenfassung:[EN] The effects of high temperature environmental exposition and of soft curing treatment on the interlaminar shear strength for vinylester glass fibre multilayer composites have been studied. The degradation effects on the matrix and fibre¿matrix interface are due to scissions of polymer chains, the oxidation process, the weakening of fibre¿matrix bonding. Possibility of stabilization of Glassfiber ¿ Vinylester-Bisphenol-A composite for prolonged high temperature service by low temperature curing is established.
