ANÁLISE TÉRMICA DE UM ECO COMPÓSITO DE POLIURETANO DE MAMONA COM REJEITO DE MADEIRA.

This paper aims to conduct a comparative analysis of composite materials subjected to apparently density tests and thermal tests. It will be made three samples. These materials will have as polymer matrix polyurethane (PU) with base of castor beans. A sample will be done with pure PU and the other two will be reinforced with sawdust and other wood-shaving in the proportion of 20% of the body made of pure PU. The PU was obtained commercially, while the wood was recycled from the tailings joinery. Through the thermal tests, it became possible to evaluate the behavior of its thermal properties. The fabrications of composites were made in metallic molds. With the study, we concluded that the materials reinforced with wood have a lower thermal conductivity and they are more apt to use as thermal insulation. [ABSTRACT FROM AUTHOR]
