摘　　要：In this research work, fiber extracted from the bark of <i>Cola</i> <i>lepidota</i> (<i>CL</i>) plant, grown in the flora of Southern part of Cameroon, was investigated for composites reinforcement. The investigation was carried via evaluation of <span>water absorption capacity, moisture content, real density, porosity, chemical composition, chemical structure and thermal behaviour. It was discovered that the new fiber has relatively low moisture content and water absorption capacity similar to those of other investigated natural fibers such as flax, sisal, coconut, hemp and jute. Its porosity was found appropriate for composite production and the fiber was found to be thermally stable up to 230°C, with maximum degradation temperature of 325°C. The main constituents of the fibre include cellulose, hemicellulose and lignin. In conclusion, based on the properties investigated, this fiber is considered suitable for composite manufacture.In this research work, fiber extracted from the bark of <i>Cola</i> <i>lepidota</i> (<i>CL</i>) plant, grown in the flora of Southern part of Cameroon, was investigated for composites reinforcement.
