摘要

The study examines the feasibility of using MDF (Medium Density Fiberboard) waste as reinforcement in orthophthalic polyester resin, evaluating its potential as an alternative to mineral filler for industrial applications. The orthophthalic resin was chosen because it's good performance, low cost and easily obtainable. Three composite compositions were prepared containing different amount of waste MDF (10, 15 and 20%). The mechanical properties, degree of crystallinity and water absorption of the resin and its respective composites were evaluated. The results show a decrease in mechanical strength and crystallinity index followed by an increase in water absorption index caused by poor adhesion in the region of the polymer matrix fiber interface.
