Palm Fibre is produced from oil palm's
vascular bundles in the Empty Fruit
Bunch (EFB).
Palm fiber itself is 100% natural, non-
hazardous, biodegradable and
environmentally friendly.
Nowadays, natural fibres from
agriculture are rapidly investigated
for multiple usages in many
structural and non-structural
applications.
Examples are as lining for
automotive components and
wood-based materials for acoustic
absorption.
Advantages of coir fibres - Lightweight
- Strong
- High Durability
-
1 . Existing composites such as carbon fibre and fiberglass have problems
- Expensive
- Health and safety issue. E.g. Fiberglass effect towards eye and lung.
2 . Oil palm has produce huge amount of wastage in the form of natural fibre every year and has low rate of decomposition.
3 . Nowadays natural fibre have less in strength compare to synthetic fibre . Oil palm fibre are well known in fabrication due to high tensile strength. So we need to test on their strength in the form of composite.
-
To produce the sample of oil palm fibre composite for three point bending test.
Preparing the specimen according to the ASTM E8
To mix the oil palm fibre and polyester resin with correct amount of percentages.
Test the specimen with different amount of polyester resin and oil palm fibre.
To collect the data based on the three point bending
-
Oil Plam Fibre
1. It take from retting process of
empty fruit bunch (EFB)
2. Brown in colour.
3. High tesile strength ang
elongation.
4. Slow rate of decomposition.
Polyester resin.
Cheaper
Long lasting
Durable
-
Unidirectional A single layer reinforcement
with all of the fibre oriented in
either the longitudinal or
transverse direction.
BIAXIAL The two layer reinforcement
which two possible
configurations. The most
common is to have one layer in
0 degree direction and the
other layer in 90 degree
direction.
-
DOUBLE BIAS
A biaxial reinforcement where
the layer are in the + 45 degree
and 45 degree direction.
TRIAXIAL
A three layer reinforcement that
can be either Longitudinal or
Transverse.
-
QUADRAXIAL
A four layer stiched fabric with one layer in each of the four primary
directions : 0 / +45 / 90 / -45 degree.
-
Material :
-
1. Clean the mould using rag.
2. Apply mold release (wax) three times and wait 5 minutes for every interval.
3. Weight the oil palm fibre at 15 gram using electronic weighing scale and put it on the mould with randomly orientation uniformly thickness..
4. Combine the epoxy resin and hardener with ratio .
5. Then pour the resin into the mould and mix it with the oil palm fibre.
6. Then put the mould container at room temperature with good air ventilation .
7. Wait at least 8 hour before removing the composite from the mould.
8. Remove the composite and detect any defect.
9. Apply resin on the defect with ratio 2:1 to hardener until the surface is parallel with others.
10. Repeat step 1 until step 9 for 25 gram and 40 gram of coir fibres.
-
Prepare 5 specimens for each 15 gram, 25 gram and 40 gram
volume of oil palm fibre composite according to the ASTM
D790.
Make a dimension 5 inch length and 0.5 inch width.
10% of each specimen length is marked at both ends of the specimen and middle of the specimen also being marked.
5 inch
0.5
inch
-
The main idea of this project is to
generate alternative composite material
from the natural fibre to reduce the
problem arise from the previous material
at the same time able to gain the same
strength. Also we want to find the
suitable ratio between fibre and resin
that can obtain the maximum strength.
