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.
Highlights
Polyethylene is a thermoplastic polymer combining a series of physical and mechanical properties such as a low density and a good strength-weight ratio, which together with the easiness to process it, becomes suitable for a great variety of applications, being plastic the mostly produced one (1, 2)
The low elasticity modules can be an inconvenience in certain occasions, as movements higher than the admitted by the standards regulating collective protections (CP) used are reached with High density Polyurethane (HDPE) systems
Are the results obtained in each of the temporary edge protection systems (TEPS) and the described settings, when the load is applied over an area of 100 x 100 mm on the upper part, at 1m height
