The study was conducted to investigate the effects of natural weathering on linear low density polyethylene (LLDPE)/Cyperus Odoratus (CY) biocomposites. It was carried out in the northern part of Malaysia, where the composites were exposed to natural weathering for 1 year. The exposed samples were collected after every 3, 6 and 12 months for degradability tests, by means of tensile tests, a morphological study and weight loss measurement of the sample. Results of the tests revealed that, within the 1 year of exposure to weather, tensile strength and elongation at break of the composites decreased, while their Young's modulus increased. The deterioration in weight properties of the composites was investigated. It was also found that, the presence of CY filler in the composites significantly accelerated the degradation of the LLDPE/CY biocomposites.
