In this work, partially biodegradable green composites have been developed with the help of compression molding technique. Jute fibers were selected as a reinforcement and epoxy resin as matrix material. The influence of alkali treatment on various mechanical properties of jute/epoxy composites was investigated, with concentrations ranging from 1%, 3%, 5%, 7%, and 9% NaOH solution. Various test results indicate that with an increase in concentration, tensile and flexural strength increases up to 5% concentration of NaOH, thereafter both the properties decrease, but impact strength increases up to 7% concentration and thereafter decreases. The results of mechanical characterizations were further validated through the study of morphology with scanning electron microscopy and Fourier transform infrared analysis. The optimal concentration of 5% concentration for alkali treatment of fibers have been suggested.

Glass Fibre Reinforced Plastics

Bio- and green composites are mainly used in non-structural automotive elements like interior panels and vehicle underpanels. Currently, the use of biocomposites as a worthy alternative to glass fibre-reinforced plastics (GFRPs) in structural applications still needs to be fully evaluated. In the current study, the development of a suited biocomposites started with a thorough review of the available raw materials, including both reinforcement fibres and matrix materials. Based on its specific properties, hemp appeared to be a very suitable fibre. A similar analysis was conducted for the commercially available biobased matrix materials. Greenpoxy 55 (with a biocontent of 55%) and Super Sap 100 (with a biocontent of 37%) were selected and compared with a standard epoxy resin. Tensile and three-point bending tests were conducted to characterise the hemp-based biocomposite.

Fiber Volume

Rising environmental concerns and depletion of petrochemical resources have resulted in an increased interest in biodegradable natural fiber-reinforced polymer composites. In this research work, jute fiber has been used as a reinforcement and polylactic acid (PLA) as the matrix material to develop jute/PLA green composites with the help of compression molding technique. The effect of fiber volume fraction ranging from 25% to 50% and curing temperature ranging from 160°C to 180°C on different samples were investigated for mechanical properties and water absorption. Results obtained from various tests indicate that with an increase in the fiber volume fraction, tensile and flexural strength increases till 30% fiber fraction, thereafter decreases with further increase in fiber content. Maximum tensile and flexural strength of jute/PLA composites was obtained with 30% fiber volume fraction at 160°C curing temperature. The trend obtained from mechanical properties is further justified through the study of surface morphology using scanning electron microscopy.
