The structure and construction of ships made of aluminum alloy, generally of the type of wrought aluminum alloy, when experiencing fatigue failure caused by cracking of the ship structure, is a serious problem. Judging from the ‘weaknesses’ of aluminum material for ships, this chapter will explain the use of alternative materials for ship building, namely aluminum-based composite material which is an aluminum alloy AlSi10Mg (b) ship building material based on the European Nation (EN) Aluminum Casting (AC) - 43,100, with silicon carbide (SiC) reinforcement which has been treated with an optimum composition of 15%, so that the composite material is written with EN AC-43100 (AlSi10Mg (b) + SiC * / 15p. Composite ship model using ANSYS (ANalysis SYStem) software to determine the distribution of stress. The overall result of the voltage distribution has a value that does not exceed the allowable stress (sigma 0.2) and has a factor of safety above the minimum allowable limit, so it is safe to use. The reduction in plate thickness on the EN AC-43100 (AlSi10Mg (b)) + SiC * /15p composite vessel is significant enough to reduce the ship’s weight, so it will increase the speed of the ship.

The structure and construction of the ship is made of aluminum alloy, generally are of wrought aluminum alloys, when experiencing fatigue failure caused by a cracked vessel structure, is a serious problem. Reviewing of 'weakness' of wrought aluminum alloys for the ship, then in this study tries to provide material alternative for ship building is composite material based on aluminum casting AlSi10Mg (b) and reinforcing material silicon carbide (SiC), which has been in-treatment with the optimum composition 15%. Analysis of numerical computation with the help of ANSYS software version 2.00 to be made numerical modeling ship to ship aluminum EN AC-AlSi10Mg (b) and ship composite EN AC-AlSi10Mg (b)+SiC*/ 15p whether the material can be applied to building ship for see the distribution of stress . The results of the stress distribution in both of model numerical of ship, its value does not exceed the stress permits (sigma 0.2) and have a factor of safety above the minimum allowable limit, so it is safe to use. The overall, in numerical modeling, the ship material aluminum and ship composite materials can be used as an alternative material for ship building, however is still needed comprehensive testing in the field.Keywords: Aluminum casting ; ship building ; composite EN AC-43100(AlSi10Mg (b))+SiC*/15p; ANSYS ver.12,0

Reinforced Composite Material

T-joints between fiber reinforced composite material components are widely used in ship building. They are the weak positions in ship structure on mechanical properties aspect. Through experiments, the effects of structure size and technics on joint deformation and destructive strength were researched. Destructive strength first increases with the increase of T-joint fillet radius dimensions, then declines when radius dimensions over R50mm. Compared with control group, composite material components with surface sandblasting process has got superior performance, with destructive load improved by 2.1 times and displacement 1.16 times. With the increase of pressure and injection time of sandblasting process, the destructive strength of joints increases. While destructive strength increases slowly when pressure achieved 0.6 MPa and injection time achieved 100s.

The liquid forging process has the flexibilities of casting in forming intricate profiles and features while imparting the liquid forged components with superior mechanical strength compared to similar components obtained via casting. Additionally, liquid forging requires significantly lower machine loads compared to solid forming processes. Currently, components that are formed by liquid forging are usually casting alloys of aluminum. This paper investigates the suitability of liquid forging a wrought aluminum alloy Al-6061 and the mechanical properties after forming. The proper handling of the Al-6061 alloy in its molten state is important in minimizing oxidation of its alloying elements. By maintaining the correct alloying composition of Al-6061 after liquid forging, these Al-6061 samples can subsequently undergo a suitable heat treatment process to significantly improve their yield strengths. Results show that the yield strengths of these liquid forged Al-6061 samples can be increased from about 90MPa, when they are in the as-liquid forged state, to about 275MPa after heat treatment. This improved yield strength is comparable to that of Al-6061 samples obtained by solid forming processes. As such, the liquid forging process here has been shown to be capable of forming wrought aluminum alloy components that has the potential for structural applications.

Stress And Deformation

In the welding process, the welding strain and deformation of the city rail aluminum alloy flankwall are inevitable as a result of local heating, and carrying capacity of the structure will be affected by the welding stress and deformation. In the mean time, it puts forward some requirements for the clamp process, the clamping force can reduce the deformation of the workpiece. But a great change of force will produce in the clamp position during the process of welding, this force changes are easy to cause brittle fracture and fatigue damage of the clamp. In this paper, it gives simulation analysis to workpiece by using ANSYS analysis software and Gauss heat source model. Finally, the conclusion is sum up compared with the actual data.

Collective Experience

<p>Fibreglass-reinforced polyester (GRP) is the most widely used composite material in the ship building industry and requires careful study in point of mechanical characteristics. This article presents the collective experience related to behaviour in different situations of GRP loading. We considered three cases manufacturing for GRP: layers with mechanical characteristics for each layer, composite (the material is considered isotropic but with layers and same mechanical properties for all layers), and isotropic plates.</p>
