Métodos de obtenção de fibras de bambu para compósitos de matriz polimérica

Abstract

Currently, there is a great concern to create more sustainable materials, in this context, is the polymer matrix composite added natural fiber. Within this class of fibers, one of the most used is the bamboo fiber, which presents a great challenge due to the difficulty in obtaining exceeding the critical length of use, which is an average of 200 mm. Fibers of this size are considered long and is mainly used for making composites as reinforcing filler within the matrix. It is therefore of vital importance to determine simple methods of getting the fibers to obtain better results on the purpose of the composite. This paper presents a clear mechanical and chemical processes to obtain short bamboo fibers, particulates and long, with their mechanical potential through mechanical tests. When performing chemical and mechanical testing, the procedures that showed better results than the natural fiber were tested to mercerization 5% NaOH in aqueous solution and acetylation for an hour at 100°C.
