Durability of GFRP composite exposed to outdoors weathering

Twelve ply glass fibre-reinforced plastic (GFRP) composite samples, hung in the open for out-doors ageing, were characterised in terms of moisture intake, inter laminar shear stress (ILSS) (using 3-point bend test) and glass transition temperature (Tg) (using low temperature differential scanning calorimetry; DSC) as a consequence of the exposure to out-doors. The local relative humidity and the temperature fluctuations were recorded. The...
