In this present work, palm fibre is incorporated in a polyester resin matrix to form unidirectional reinforced composites and bi-directional composites. Samples of different fibre volume fractions are fabricated and specimens with 0°, 45° and 90° fibre orientations are prepared. The specimens are tested on a universal testing machine applying tensile force. The tensile strength is measured as a function of fibre volume fraction. These properties follow \“Rule of mixtures” relationship, with the volume fraction of palm. Because of the low density of natural fibers and high electrical resistance, these composites are more suitable for electrical and mechanical applications. Keywords: palm fibre, hand lay up technique, mechanical and electrical properties. 1 Introduction There is a great interest in the development of new materials which enhance optimal utilization of natural resources, and particularly of renewable resources. Natural fibres such as palm, jute, coir, banana, sisal etc., belong to this category. These fibres are abundantly available in developing countries, particularly in
palm fibre, hand lay up technique, mechanical and electrical properties.
