Mechanical, morphological and water thermal, absorption properties of epoxidized palm oil-based epoxy resin

Abstract EN

A mixture of epoxidized palm oil (EPO) and epoxy resin (DGEBA) has been successfully studied for mechanical, thermal and water absorption.

Different percentages (10, 20, and 30 wt %) of EPO were mixed with epoxy resin and cured with a cycloaliphatic amine curing agent.

The thermal behavior of EPO/epoxy blends was characterized using Fourier transform infrared spectroscopy, differential scanning calorimetry and dynamic mechanical analysis.

However, the glass transition temperature and storage modulus of the system decreased with increasing EPO loading.

The addition of EPO decreased the tensile and flexural properties and increased the elongation at break and impact strength.

This indicates an increase in epoxy mobility and toughness.
