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.
