Abstract :
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.
