Polyester and Hymenaea Courbaril Residue for Sustainable Composite Manufacturing

Abstract

Objective: To evaluate the mechanical behavior of polymer composites reinforced by wood residue known as Játobá (Hymenaea Courbaril), in powder form. It aims to reduce impacts to the environment through the use of waste. Theoretical Framework: Composites are generated from the union of materials, aiming to obtain specific properties arising from their components. Usually these are divided into two phases, matrix. The possibility of using materials less harmful to the environment in composite has gained prominence in research in the area. Method: To obtain the properties of the composites, standardized specimens were manufactured according to ASTM D638. The matrix selected was terephthalic polyester resin and the reinforcement was Játobá wood residue, in the form of powder. The results were obtained by tensile strength tests. Results and Discussion: The average value of tensile strength obtained was 11.76 (±1.70) MPa. The comparison of the results of this study with other literature revealed the superiority of the tensile strength of the composite of the present work in relation to others with different reinforcements of wood residues. Research Implications: The use of wood waste in composites is beneficial for reducing the irregular disposal of matter in the environment. Also, it aims to generate added value to a useless material. Originality/Value: The use of natural and renewable materials as reinforcement in composites is of great relevance, aiming to reduce the use of synthetic raw material. In addition, there is the manufacture of composites of low cost and weight and feasibility of manufacture.
