This paper presents an ongoing research on the durability of pultruded Glass Fiber Reinforced Polymer (GFRP) composites applied, as structural or cladding members, to building construction. Three different compositions of pultruded profiles have been tested: Vinylester/E-glass, Isophthalic Polyester/E-glass and Orthophthalic Polyesther/E-glass. The degradation of the mechanical and aesthetical performance of the composites have been monitored through a process of artificial ageing in a climatic chamber, simulating the combined effect of high temperature, freeze-thaw cycles, moisture (high levels of relative humidity close to the saturation grade) and UV radiation.

Abstract
This paper presents an ongoing research on the durability of pultruded Glass Fiber Reinforced Polymer (GFRP) composites applied, as structural or cladding members, to building construction. Three different compositions of pultruded profiles have been tested: Vinylester/E-glass, Isophthalic Polyester/E-glass and Orthophthalic Polyesther/E-glass. The degradation of the mechanical and aesthetical performance of the composites have been monitored through a process of artificial ageing in a climatic chamber, simulating the combined effect of high temperature, freeze-thaw cycles, moisture (high levels of relative humidity close to the saturation grade) and UV radiation.| File | Dimensione | Formato | |
