Sažetak
Ripstop fabrics are commonly used for outdoor applications. Their sensitivity to atmospheric conditions is an important issue for materials selection. In this paper different ripstop materials have been exposed to artificial weathering conditions and their mechanical properties have been tested before and after 1,000 hours of accelerated weathering. Three different types of fabrics have been examined. Woven fabrics were made of (i) ripstop polyamide coated with thermoplastic polyurethane, (ii) ripstop polyamide coated with polyurethane and aluminum and (iii) polycarbonate-coated ripstop polyester. Mechanical properties are directly influenced by the type of fabrics and aging degree, but impact tensile tests and tensile tests with low force rate show that the deterioration of mechanical properties depends on testing velocity as well. This conclusion is an important issue for materials selection for outdoor applications.
