Investigations on biocomposites from oat hull and biodegradable polymers
Authors: Kaur Grewal, R., M. Soleimani, L. G. Tabil
Description: Oat hull is abundantly available biomass in Canada, which is mostly used as low-value feed material. However, oat hulls with high fibre content can be used in the production of industrial products by providing opportunity in the replacement of petroleum-based products. The objectives of this investigation are to develop biocomposites from cellulose and lignin which are post-hydrolysis products of oat hull using biodegradable polymers (polylactic acid and polycaprolactone) and to compare the physical and mechanical properties of formulated biocomposites with polypropylene (PP) biocomposites so that a low cost and eco-friendly biomaterials can be made. Inclusion rates of AHB (acid-catalyzed hydrolysis byproduct) and CRB (cellulose-rich biofibre) fibres at 15% and 30% of the total mass of biocomposites were formulated. The composites with different formulations were extruded through the twin-screw extruder for compounding and thereafter were compression molded. The physical and mechanical properties such as color measurement, water absorption, tensile strength and flexural strength of formulated biocomposites were determined. The results indicated that strength of bicomposites generally varied to that of virgin polymers, while Young’s modulus increased with corresponding increase in fibre content from 15% to 30%.
