This study describes a methodological proposal to select composite materials which are suitable to be employed to manufacture pipes that can properly withstand environments subjected to gamma and neutronic radiation. The methodology is used to select, among many others, the optimal composite material whose properties are used afterwards to simulate several pipe sections by finite element analysis, comparing the results with a well-known nuclear-grade steel, WWER 15Kh2MFAA. The most suitable composite material according to the defined criteria is composed of a phenolic resin matrix reinforced with long boron fibres and exhibit great properties to be used in a nuclear reactor environment: good radiation resistance and mechanical properties with a very low density at low cost. It can be concluded that, in some cases, composite material pipes can be a better option than steel ones. Extending the method to be employed in other industries or with other components could be seen as future works.

Wound Composite

A stability analysis is developed to assess the stresses and dynamic characteristics of the wound composite material axial impeller under centrifugal force loading conditions. This procedure is based on finite element analysis (commercial software ABAQUS) results. A low-cost, light-weight, high-performance composite turbomachinery impeller with a uniquely designed blade patterns is evaluated. Understanding the stress–strain behaviour of fibre-reinforced composite laminates as it relates to ultimate failure and the ability to predict ultimate strength is critical in the design of safe and lightweight impellers. To determine failures, the maximum stress failure criterion is used. In order to avoid operating at resonance, which can make impellers suffer a significant reduction in the design life, the designer must calculate the natural frequency and modal shape of the impeller to analyse the dynamic characteristics. The results show that using composite Kevlar fibre/epoxy matrix enables the impeller to run at a rotating speed 2228 rad/s and withstand the stresses, no critical speed will be matched during start-up and shut-down, and that mass imbalances of the impeller shall not pose a critical problem.

Special Working

As a special lifting device, the lifting pole is widely used in construction of transmission line powers. Due to the special working environment, a new-type lifting pole made of carbon-fiber reinforced resin matrix composites is designed to facilitate transportation and usage. It is shown by comparison of material properties that new materials can greatly reduce structural self-weight on the condition of ensuring mechanical properties. In order to ensure the equipment is used safely and reliably, this paper carries out mechanical calculation and ANSYS finite element analysis by setting up a mechanical model, and the results show that the design is reasonable and accords with national relevant specifications.

When offshore oil field has been completed and put into production, the new subsea pipelines and cable will need to be established. Cable protection pipe clamp is used to fix cable protection pipe on the jacket. In order to avoid the problem of traditional steel structure clamps which was difficult to joint, align and fasten when it installed cable protection pipe underwater, reduce the risk and workload underwater, This paper will study a new type of portable connecting riser clamp made of resin matrix composites which can solve the installation problem which is difficult to install cable protection pipes underwater. The main structure of pipe clamps made of resin matrix composites used three divided-plates type of structure. The load characteristic of clamps was determined by Morison equation which is a classical theory and clamps underwater mechanics analysis model was established. The results show that the strength of the base of clamps meet the requirements after strength analysis with finite element analysis method, stability and strength experiments, which means the clamps made of resin matrix composite is feasible.

In recent years, composite material is used as an alternative material for materials like metal, wood, etc. due to low in weight, strength to weight ratio and stiffness properties. Natural fibers like coir fiber, palm fiber, jute fiber, banana plant fiber, etc have low cost, easy availability and less harmful to human body. Also, carbon fiber having various properties such as high strength to weight ratio, rigidity, good tensile strength, fatigue resistance, fire resistance/not flammable, high thermal conductivity. This research work aims to find out the mechanical properties of Carbon fiber, Coir fiber and Epoxy composite material with different ply orientations angles by using FEA software Ansys APDL R15.0.

E GLASS and Aluminum mixture composites remain a modern group of the metal matrix composites with an ability to meet the needs of specialized manufacturing submissions. Aluminum mixture strengthening technology is a solution to the diverse and the ever-increasing service needs of an industries such by way of aviation, aerospace, automobiles, and a maritime, among others. These requirements are fulfilled thanks to better mechanical properties, the ability to manufacture aluminum hybrid composites using traditional methods, and the prospect of lowering production costs. Meanwhile of the manufacturing constraints are linked to the strengthening particulates, the efficiency of these products is largely reliant on choosing the correct mix of reinforcing materials. The results of this study show that E-Glass and Al-based hybrid composites have a lot of potential as a replacement for earthenware reinforced compounds and unreinforced Al-alloys in a variety of locomotive submissions that require low cost, in height strength-to-mass ratio, and greater dress confrontation.
