Abstract:
The joint of composite, mild steel and aluminium structures have been applied in
numbers of engineering fields, including composite boat and ship structures. From a
production viewpoint, large and complex structures cannot be formed in one process,
thus introducing the need for several components to be joined to produce the
completed structure. Each of material joint is very important in order to ensure ships
can always be sturdy and durable. Each material has their own advantages in making
material joint such as possible reductions in topside weight and increased resistance to
corrosion. While each types of joint have different strength and its own advantages.
As for this matter, different material is used to determine the strength of the joint
material using universal testing machine. Mechanical characteristic of each material
joint which is composite, mild steel and aluminium is carried out. A comparison was
done by identified the strength of the joint between butt joint and lap joint with three
different materials.The results of experiment indicate that mild steel is the strongest
joint between aluminium and composite while butt joint is the strongest joint
compared to lap joint.
