Natural fibre is one of the excellent reinforced materials that are tough and hard and have found to be a potential reinforcement. The different natural fibres sisal and rice
husk fibres seem to be promising materials because of the high tensile strength of sisal fibre and the toughness of rice husk fibre Jacob et. al., 2004.
1.2 Problem Statement
There is a major weakness in the edge clamp for milling table production in the current production tool design in the industry, and the weakness is the cost to produce
the edge clamp is high. This is due to material use for edge clamps are made from metal such as stainless steel, carbon steel and other metals. The cost also includes the
fabrication of the tools and the material. Other than that, even though the metals are one of the best materials for tooling production, but metal is not green technology
material. This is the reason of use Tin as the composition in producing production tooling because it is easy to find, cheap and recyclable. As the rice husk is a natural
fibre, it cannot stand alone to make a product and need combination with other metals such as Tin to make the properties much stronger than before. Therefore, in this
report, the enhancement plans for quality improvement and cost reduction by applying Tin and Rice husk will be well proposed. For the process, sand casting process will be
applied in this project because sand casting is one of the easier techniques of casting.
1.3 Scope
This final year project was mainly about the analysis of the composite material base on the composition between Tin Sn and Rice Husk Fibres that will apply in the
experiment to get the suitable result in making production tooling. Besides that, an experiment will be conducted by making specimen to be test. In order to make the
specimen, the process that involve is hot press. Other experiment and material will be not covered in this research because of time limitation. Besides that, design and
analysis of the edge clamp, fabrication of edge clamp and fabrication of mold pattern using rapid prototype also will be not covered in this research.

1.4 Objective
The objectives of this research are to: 1.
To find the suitable composition between Tin Sn and Rice Husk Fibers 2.
To test each of composition base on hardness, flexural, water absorption and tensile strength.
3. To proposed the production tool design for edge clamp design with the
suitable material.

CHAPTER 2
LITERATURE REVIEW
The literature review is definitely to the ideas and knowledge on a topic that we cover. This chapter will briefly explain about the problem issue, research objective and the
methodology that supported by the establish knowledge that review from journals, books articles and close source from the internet. In Chapter 2, project report
provided the introduction to the specimen that used in order to make strap clamp. Hot press machine to make the specimen is reviewed in this chapter. Besides that, this
chapter review of the types of testing will be used for this project such as tensile test, surface roughness test and hardness test. Furthermore, material properties of Tin,
Rice Husk and Silicon Carbide which is the materials used to produce the clamp by using sand casting process also include in this chapter. The sand casting process also
consists in this review but not to detail.
