Abstract
Balsa wood is a lightweight, tough material and is largely used in the manufacture of radio-controlled aircrafts. By combining low specific mass and high mechanical strength, the material has been proven efficient in its applications. Therefore, it is very common to manufacture composite materials from balsa wood to provide better mechanical properties allied to the wood low specific mass. This paper evaluated the behavior of the mechanical properties of wood as well as confectioned and realize mechanical tests of traction and bending in composites made from a balsa core and coated with carbon fiber coated being varied the resin used during the manufacturing process. The proprieties characterization of the wood and composites shows that, the process of laminating wood with carbon fiber provides a significant improvement in the mechanical properties of the specimen. Moreover, the use of epoxy resin proved favorable to the use of polyester resin, since the first provides a higher limit of traction resistance, flexural resistance and a lower final density of the material.
