NUMERICAL INVESTIGATION AND CHARACTERIZATION FOR GLASS FIBER REINFORCED POLYMER AND CARBON FIBER REINFORCED POLYMER COMPOSITE FOR HIGH CORROSION CHEMICAL TANK

Mechanical Engineering

Light weight design and construction is a major benefit for transportation tanks. In many countries, regulations impose a limit on the gross mass of road vehicles. The gross mass of the vehicle includes the tank, its cargo, the trailer, and prime mover. The transportation of liquid dangerous goods is a worldwide industry. Steel and aluminum are the main materials used to fabricate transport tankers to support this industry. These materials are used for different purposes. Aluminum is lightweight, cost effective, and competitive for use where liquid cargoes are mild to noncorrosive, such as Class 3 (flammable) dangerous goods. Steel is used where aluminum is not possible, which is mainly for transport of corrosive chemicals, classified as Class 8 dangerous goods. Generally, the use of mild steel is preferred in terms of cost, but is often not possible due to limited corrosion resistance. If higher corrosion resistance is required stainless steel may be suitable. Some Class 8 corrosive chemicals require special consideration in terms of the materials that the transport vessel is made from, as these can attack the stainless steel materials. Fiber reinforced polymers (FRPs) are emerging as an important alternative to steel materials for the transport industry, and these materials can be used with or without liner.
