Polylactic acid and cashew shells were characterized by FTIR, scanning electron microscopy, thermogravimetric analysis, lignocellulosic analysis, and for the composite materials obtained, mechanical tests were carried out to obtain tensile and flexural mechanical properties according to ASTM D638 and ASTM D790 standards, In addition to the analyzes of the fractures obtained in each test. It was found that the shell has the presence of hemicellulose, cellulose and lignin, in addition to other minerals present in smaller quantities. The drying process at 250ºC managed to eliminate the anacardic acid present in the cashew shell. It was evidenced that the composite materials with 0.5% cashew shell particles had higher values of modulus of elasticity and tensile strength, however, in the yield stress, the 1% composite materials presented the highest properties. On the other hand, in bending, an increase in bending resistance was observed as the percentage of added particles increased.RESUMEN ...................................................................................................................... 7ABSTRACT..................................................................................................................... 81.
