Cover Story: Polyurethane foams are widely used but are brittle in tension and bending. This study explores the mechanical properties of fibre-reinforced polyurethane (FRPU) foams with natural henequen fibres. Pull-out tests identified an optimal foam density of 100 kg/m3 with a 10 mm fibre length. FRPU foams with this density and fibre contents of 1, 2, and 3 wt% were tested. Compression tests showed increased elastic modulus and yield stress, with a maximum 71% increase in the compressive yield stress for 2% fibre content. The FRPU foams also absorbed more energy than the unreinforced PU foam. Flexural tests revealed a 40% increase in flexural strength for 1% fibre content. These findings highlight the potential of FRPU foams with henequen fibres as sustainable materials with enhanced mechanical properties. View this paper
