Abstract

This study investigates the modification of epoxy resins with pyrolysis bio-oils derived from plant waste, aiming to enhance mechanical performance. A method for epoxy resin modification using bio-oil is proposed, including techniques for bio-oil pretreatment, purification, and incorporation into epoxy resin. Three pyrolysis bio-oils (birch, sunflower, and a mixed softwood and hardwood feedstock) across different concentrations were used as a modifier. Mechanical properties were evaluated under tension, compression, and three-point bending loading.

Mechanical testing revealed that epoxy resin modified with the bio-oil at an optimal concentration of 12.5 phr produced polymer system with strength characteristics comparable to epoxy resins modified with an industrial plasticizer, while demonstrating superior compressive strength properties. Combined modification with bio-oil and industrial plasticizer dibutyl phthalate resulted in enhanced both deformation and ultimate stress levels for all types of loading considered.

The bio-oil derived from the mixed wood feedstock can effectively replace the dibutyl phthalate in terms of mechanical performance while providing additional benefits in environmental sustainability and cost efficiency.
