Abstract [en]

In today’s world the significance of bio-based materials are increasing rapidly because of the environmental concern. Material scientists are nowadays engaged in development of such materials which have natural origin and degrade in its environment. Several works have already been reported in area of thermoplastic biocomposites. However biocomposites based on thermosets is comparatively new area of research. In this work biobased composites have been developed from two different bio-based thermoset resins. The main objective of the work was room temperature curing of poly lactic acid based resin (POLLIT™) and AESO, acrylated epoxidized soy-bean oil (TRIBEST®). These two resin systems were impregnated with different natural fibre mats. Cure behavior was characterized by means of DSC (Differential Scanning Calorimeter) and results shows that the resins have been cured at room temperature. The mechanical properties of prepared composites were assessed by the means of flexural testing and charpy impact testing. The viability of using these composites in structural applications are also been discussed.
