Moisture absorption and degradation of Glass fiber/Vinylester composites
2010 (English)In: Selected papers of the International Scientific Colloquium "Modelling for Material Processing": Riga, Latvia, 16 - 17 September, 2010 / [ed] A. Jakovics, Salaspils: University of Latvia Press, 2010, 157-162 p.Conference paper (Refereed)
Vacuum Infusion is a closed mould manufacturing process that can replace open mould processes. To improve resin flow it is common to add flow enhancement layers to the reinforcement stack. This paper is aimed to analyze water uptake in these materials and its effect on mechanical performance. Ageing data for 3000 h in 90ºC water are presented for GF NCF/VE composite without flow layer and three composites with it. Tensile tests demonstrate degradation of mechanical properties and increasing viscoelastic and viscoplastic strains in wet composites.
