Desenvolvimento e aplicação de compósitos à base de matriz polimérica reforçado com fibras de curauá (Ananás erectifolius) e resíduos de madeiras amazônicas.

Abstract

The search for new unconventional materials for construction based on renewable sources has contributed to environmental issues and sustainable development. In the current context of environmental and technological fibers in the Amazon region have become increasingly prominent, with respect to its use in products from various sectors of engineering. Among these, one can cite the example of curauá (Ananas erectifolius), species of bromeliad that is part of the pineapple family curauá has become a very attractive plant, both the economic point of view, because it has easy access and require low labor cost, as the scientific point of view, because it has low density and high strength. This paper presents a study of the viability of production and assessment of curauá (Ananas erectifolius) fiber panels, with and without wastes of Amazonian timber species amapá-doce (Brosimum parinarioides Duk) and louro-inhamuí (Ocotea cymbarum H.BK.), produced under pressure with bi-component polyurethane resin-based castor oil. The study was divided into three stages, the first characterizations were made physical, chemical and mechanical properties of the fiber, and the second time fabricated panels and the tests of bending, tensile and screw perpendicular surface according to standard NBR 14810-2. The results indicate that the panels showed good mechanical and physical properties, which is in accordance with the Brazilian standard. It is hoped that the study will enable the development and future generation of longer an option alternative material for the construction industry, so it is proved its good performance and can meet the technical requirements for the construction and furniture area.
