A new bio-composite was developed by adding banana tree fibres to a polypropylene matrix. Banana fibre was chosen due to its abundance and relative low coat. The physical, chemical, mechanical and thermal properties of the bio-composite were investigated. The material was characterized using the following tests; Izod impact resistance, tensile strength, hardness, specific weight and differential scanning Calorometry (DSC). The banana fibres (BF) were extracted from pseudosterm of banana tree and mixed with a thermoplastic polypropylene (PP) compound in the proportions of 90/10% (PP/BF), 80/20% (PP/BF) e 70/30% (PP/BF) by weight, using an extrusion process to prepare the samples. The properties were compared with PP (100%). The composites made of PP matrix containing banana fibre showed an improvement in impact properties as well as specific weight and thermal conductivity. Chemical and thermal stability also improved. 1. INTRODUCTION Polypropylene (PP) is a very important semi crystalline thermoplastic for technological applications due to its strength, excellent melt processability, fast crystallization, low density, good mechanical properties and high thermal stability. Polypropylene has a long-term durability against environmental degradation and may experience some biodegradability if mixed with natural fibres (Xiaofei et al., 2008; Howard, 2002). The difficulty of synthetic polymer materials to degrade led to the development of sugar biopolymers. (Howard, 2002). However the mechanical properties of biopolymers are inferior to synthetic polymers for the majority of the commercial applications. Composites are very singular materials as they distribute the properties of all components. The most used materials for reinforcement of polymer composites by the plastic industry are natural fibres and minerals (Park et al., 2008). In the last decade a huge emphasis has been made on the fabrication and use of polymer natural fibre composites instead of synthetic fibres such as glass fibre, carbon fibre, Kevlar amongst others mainly because of costs and the environmental impact these materials cause (Barcellos et al., 2009; Martinelli, 2008). Biodiversity allows an enormous amount of natural vegetable fibre options that could be used in polymer composites. Furthermore vegetable fibres are renewable resources with a high potential to modify thermoplastic. The most common are; sisal, jute, curaua, coconut, sugar cane bagasse, wood powder and banana tree fibre. Kaemple et al. (2002) observed that PP natural fibre composites require special preparation of the fibres prior impregnation into
