Abstract


We have tested under static and dynamic load temporary edge protection systems (TEPS) formed by a continuous fence, some are made of high density polyethylene (HDPE) and others have been manufactured using a composite material, adding glass fiber at a matrix of HDPE at a rate of 4%. Tests under static and impact have been performed according to standard UNE-EN 13374, class systems A and B. It has been found the influence of aging on TEPS and samples of the same materials as the TEPS. All tested TEPS exceed the strength requirements and accidental load and requirements compared to dynamic loads. The incorporation of glass fibers results in a composite material with a modulus of elasticity higher and significantly less creep. We haven’t seen dependence on the results with the degree of aging or in SPPB or in the samples.
