Effect of fabric orientation on mechanical properties of cotton fabric reinforced geopolymer composites
Abstract This paper presents the thermal, mechanical and fracture behaviour of fly-ash based geopolymer composites reinforced with cotton fabric (0–8.3 wt.%). Results revealed that fly-ash based geopolymer can prevent the degradation of cotton fabric at elevated temperatures. The effect of cotton fabric orientation (i.e., horizontal or vertical) to the applied load on flexural strength, compressive strength, hardness and fracture toughness of geopolymer composites is also investigated. The results showed that when the fabrics are aligned in horizontal orientation with respect to the applied load, higher load and greater resistance to the deformation were achieved when compared to their vertically-aligned counterparts.
Highlights Fabrication of cotton fabric reinforced geopolymer composites. Enhanced mechanical properties were achieved in geopolymer composites. Mechanical and fracture properties are dependent on orientation of fabric alignment. The geopolymer matrix protected the degradation of cotton fabrics at high temperatures.
