Use of Statistical Techniques to Characterize?Bio-Composites Made from Sisal Fibres and?Bio-Resin from Banana Peel

摘要

The purpose of this study was to use statistical techniques to characterise bio-composites?made from sisal fibres and bio-resin from raw banana peel. The fibres were treated with sodium?hydroxide, combined with a bio-resin made from banana peel, and then a bio-composite?material was developed. The effect of the fibre volume fraction, glycerine and bio-resin mass?on the bio-composite’s tensile and compressive properties was investigated using universal?rotatable design and multiple regression. The paired T-test conducted exhibited a significant?improvement in the mechanical properties of the treated fibres. Sisal bio-composite?showed a tensile strength of 5.2 MPa with an adjusted R2 value of 0.91, Young’s modulus?of 11.99 MPa (adjusted R2 of 0.92), percentage elongation of 1.77% (adjusted R2 of 0.95),?and compressive strength of 2.94 MPa (adjusted R2 of 0.90). The bio-composite could becompared to a commercial composite and solid wood boards, and hence it is an alternative?to non-renewable, non-biodegradable petroleum and solid wood products for partition,?ceiling and notice board applications.
