Global pollution due to the overwhelming usage of non-biodegradable plastics is getting severe nowadays. Hence, the aim of this paper is to develop an environmentally friendly composite material from potato starch and sugarcane bagasse. The composites were prepared by hot pressing at 145? for 60 min. The composites were characterize for their mechanical and thermal properties. In terms of thermal properties, thermogravimetric analysis shows that incorporation of sugarcane fiber has improved the thermal stability of the composites. Meanwhile, incorporation of sugarcane fibre form 0 to 15 wt.% has significantly improved the tensile and flexural properties of the composites. Scanning electron micrograph of the tensile fracture showed the fibre fracture and fibre “pull-out” from the composite. Overall, the biodegradable composites has shown improved functional characteristic than the origin material. This finding shows that this Sugarcane/Potato starch composites are potential alternative material for biodegradable product i. e biodegradable plastic packaging.

Different Content

The nanometer carbon black (CB) N220 of different content was employed to prepare carbon black N220/epoxy resin (CB N220/EP) composites by filling-mixing method. The structure of CB N220 and its dispersion in epoxy resin were analyzed by TEM and tensile fracture surface of the composites was analyzed by SEM. Experimental results showed that CB N220 was dispersed in epoxy resin homogenously in the form of CB particles and it formed a good interface with epoxy resin in the presence of coupling agent (KH-550). Using of CB N220 enhanced the mechanical and thermal properties of the composites, for tensile strength, elongation at break, impact strength and flexural strength of the composites filled with 2 wt% CB N220 reached a maximum values( 82Mpa、3％、20 KJ•m-2、107Mpa), a rise of 32.3％、39.6％、88.7％、10.3％, respectively, compared to pristine epoxy resin.

Platelet Shape

The paper presents studies of influences of platelet-shape alumina content on the morphology, mechanical and thermal properties of Al2O3/epoxy composites. The alumina particles were pre-treated with surface modifier, and its addition contents were ranged from 17 to 40vol.%. It was found that tensile strength and thermal conductivity increased with the increase of the alumina contents. The fracture surface investigation showed that several strengthening mechanisms, including particles pull-out, crack pinning, plastic void growth and deformation were the main factors for the increments of the tensile strength of the Al2O3/epoxy composites. Comparing with pure epoxy polymer, the creep strain values at 70 °C for 1800 s and recovery strain after 3600 s of 40vol.%Al2O3/epoxy composites was lower as 0.23% and 70%, respectively. It was due to effective prohibition of the slippage and disentanglement of epoxy polymer molecules by the rigid Al2O3.
