Investigations on ageing of wood-plastic composites for outdoor ... Oct 15, 2016 ... It was found that high values of modulus of rupture (MOR) and Young's modulus (MOE) are considered key to an engineering design of WPC fa?ades. Both parameters are appropriate indicators to describe the ageing of WPC cladding. Weathering of WPC decreases MOE more than MOR. Exposure to...
