  Abstract

In this study, a sheet molding compound (SMC) composite was developed using a glass fiber reinforcement and a bio-based polyurethane (Bio-PU) modified vinyl ester matrix. The Bio-PU was synthesized to incorporate urethane linkages into the vinyl ester side chains through the reaction between hydroxyl (-OH) groups in the vinyl ester and isocyanate (-NCO) groups in the polyurethane, thereby forming a urethane-grafted vinyl ester network. Bio-PU-modified vinyl ester resins containing 10, 30, and 50 wt.% Bio-PU were formulated and subsequently processed into SMC prepreg using TBPB as a thermal initiator. The mechanical, and morphological properties of the resulting composites were tested and compared with those of conventional vinyl ester-based glass fiber SMCs. The mechanical strengths of all composite specimens increased with higher fiber volume fractions. However, as the Bio-PU content increased, the interfacial adhesion between the glass fibers and the resin matrix weakened, resulting in reduced tensile and flexural strengths. In contrast, the impact strength exhibited an opposite trend, increasing progressively with higher Bio-PU content. Overall, the Bio-PU-modified vinyl ester resin demonstrates strong potential as a matrix for eco-friendly, high-performance SMC composites. The material system offers a well-balanced combination of mechanical performance, formability, and environmental benefits, making it suitable for structural composite and semi-structural applications.
