Desarrollo de un composite de matriz polimérica con refuerzos de fibra de madera de pino.

Abstract

In Ecuador, 40% of each tree, is turned into waste by the cutting process and the other 40% in industrialization waste, so there is a necessity to use this resulting waste from the industrialization of wood, this work develops a board of pine wood particles through the union of polyester resin, and then its feasibility is verified in application of architectural uses. One of the main disadvantages in composites is the low adhesion between matrix-reinforcement; to improve this aspect, it has been made a chemical treatment of calcium hydroxide was carried out to improve fiber properties for physical-mechanical tests, according to low density the optimal results are given through tests of impact resistance, acoustics and heat transfer due to its ability to absorb energy, noise and decrease the ability to conduct heat. For tests to flexion, swelling, absorption, fire resistance require that the specimens are denser because higher density is less porosity and increases the resistance in these tests.
