Influence of natural fillers on the thermal and mechanical properties of epoxy resin composites

Abstract

The influence of a natural filler (lignin, chitosan, starch) used in the amount of 1, 5 and 10 wt% on thermal and mechanical properties of composites based on epoxy resin (Epidian®5) was investigated. Cross-linking of the resin with polyamine (IDA) was confirmed by the ATR/FT-IR method. The differential scanning calorimetry (DSC) was used to evaluate the thermal properties. Tensile and flexural mechanical properties as well as Shore hardness were also determined.
