To study the possibility of using a composite material made from palm fruit fibre and sawdust as
a building material, the modulus of elasticity, fracture load and the maximum deflection of mahogany sawdust
and palm fruit fibre-kotolyn veneer composites have been determined using the static bending test. The sawdust
particles were sieved into different particle sizes (d): coarse (1.1 mm≤d≤4.8 mm), medium (0.8 mm≤d≤1.1
mm) and fine (d≤0.8 mm). Briquettes were made from the sawdust of approximately same particle sizes mixed
with palm fibre in different weights proportions, using ‘wood’ glue as a binder. The briquettes were then
sandwiched between two pieces of Kotolyn veneer to form the composites. They were then subjected to
bending tests. The composite materials made from 100wt% of coarse size sawdust recorded the highest fracture
load and modulus of elasticity of 48.00×102 N and 2.23× 106 Nm-2, respectively. Among the composites
containing both fibre and sawdust, the 90% wt coarse size-10 wt% fibre recorded the highest fracture load and
modulus of elasticity of 30.90×102 N and 1.07×106 Nm-2. Mechanical strength of the composite decreased with
decreasing fibre content. The maximum deflection, however, increased with increasing fibre content. The
incorporation of fibre into the sawdust briquettes introduces some degree of flexibility into the composite
materials with a decrease in the strength and doesn’t make good building material but can be used for domestic
finishing’s.
