Evaluation of Lannea acida tree-bark particulate/fiber reinforced epoxy composites was carried out. By manually stripping the Lannea acida plant into strands and particles, fiber and particles were isolated. For the creation of the composites, the fiber and particle were then blended in the following ratios: 0:50, 5:45, 10:40, 15:35, 20:30, 25:25, 50:0. In all of the samples created, the epoxy-resin binder was kept at 50% and the hand lay-up method was used. Seven samples were produced from the particulate obtained with and without the fibers reinforcement. Physical properties, Mechanical properties, and Dynamic mechanical analysis (DMA) of the composites produced from Lannea acida tree bark particulate/fibre were evaluated.Tensile and impact strengths (15.46–21.81 MPa and 5.52–6.61 J/mm2 respectively) were found to increase as fiber content increased before sharply declining as fiber content increased. The damping factor was shown to rise with rising temperature, peaking in the transition zone and falling off in the rubbery zone.The tests obtained from the Lannea acida tree-bark particulate/fiber falls within the range when compare with work of other researchers which show that it can be used as alternative material for the production of reinforce composite that can be used in construction and manufacturing of automobile interiors and body parts.
