Experimental Study on the Tribological and Mechanical Properties of Aluminium Bonded with Alumina Ceramic | Chapter 4 | Current Approaches in Engineering Research and Technology Vol. 8

The present study highlights about Tribological and Mechanical Properties of Aluminium Bonded with Alumina Ceramic. Aluminium is a malleable and lustrous substance that is classified as a member of the boron group on the periodic table. Aluminium and its alloys possess a low weight and can provide solutions for optimizing the ratio of strength to weight in cars. However, they are unsuitable for applications that need great resistance to wear. Aluminium alloy is mixed with highly wear-resistant alumina ceramic to enhance its suitability for high-wear applications, such as brakes. Aluminium can withstand corrosion as a result of passivation. Alumina ceramic, a non-metallic material, has excellent resistance to wear. Aluminium may undergo ceramic coating by many methods such as adhesives, brazing, and thermal plasma spraying. Aluminium may be bonded with alumina ceramic using an epoxy resin, which is often used for joining both metals and non-metals. After applying epoxy resin to cover the Aluminium with ceramic, the material was subjected to tribological testing and EDX analysis to conduct research. The material may attain similar mechanical and tribological characteristics.

Taguchi and Neural Network Analysis for Predicting Abrasive Wear Behavior of Carbon Epoxy Composites | Chapter 3 | Recent Progress in Science and Technology Vol. 7

 In this study, an approach for calling the three-body nasty wear behavior of unfilled and element filled element fabric supported epoxy composite using two displaying techniques - Taguchi reasoning and artificial interconnected system are presented. A set of experiments were transported using an orthogonal array established Taguchi techniques to achieve data in a reserved manner. The results showed that the adding of graphite coarse into carbon binding material composite led to a decrease in its caustic wear resistance, and the wear deficit increased accompanying an increase in abrading distance and loads. To investigate the effect of control limits on the wear behavior of the composites, an reasoning of variance was acted, and the S/N ratio was determined. The results found that the normal load had the best physical in addition to statistical influence on the nasty wear of the composites followed by abrading distance and stuffing content. To predict the wear possessions of composites as a function of testing environments, 3-[5]1-1 neural network architecture accompanying Levenberg Marquardt (LM) training treasure was used. By equating the correlations obtained by Taguchi reversion analysis and affected neural network accompanying the experimental results it was raise that the artificial neural network thinks the wear rate better than regression reasoning. Therefore, a well-trained pretended neural network system maybe very helpful in judging the weight deficit in the complex three-body abrasive wear position of polymer composites.

Numerical Evaluation of Single-lap Adhesive Joints under Different Geometries and Adhesive Types | Chapter 2 | Techniques and Innovation in Engineering Research Vol. 3

 Adhesives can be strong and brittle (such as Araldite® AV138) or weak and ductile (such as Araldite® 2015). High strength and ductility are built into a new family of polyurethane adhesives such as Sikaforce® 7888. In this study, the performance of his three adhesives above was evaluated in single lap joints with different lap lengths (LO). Experimental work is complemented by rigorous numerical studies using finite elements based on Cohesive Zone Models (CZM). This procedure allowed us to validate the performance of this prediction technique when applied to adhesive joints. Additionally, we were able to determine the optimal adhesive family for each joint geometry. CZM has proven to be very accurate, except mainly for ductile adhesives, which can be circumvented by using another cohesion law.

Numerical Evaluation of Different Adhesive Joint Configurations by Cohesive Zone Modelling| Chapter 10 | Current Overview on Science and Technology Research Vol. 1

 Single-lap joints (SLJ), double-lap joints (DLJ), stepped joints, and scarf joints are the most typical configurations for adhesive joints. The overlap length is one of the most significant factors that influences the joint strength (LO). The major goals of this work are to compare various joint geometries using different adhesives with diverse properties and to determine which type of adhesive is best suited for each joint shape. In order to test three adhesives, SLJ, DLJ, stepped joints, and scarf joints were selected. The experimental data are contrasted with the numerical results from the integrated cohesive zone modelling (CZM) module of the Abaqus® programme. This study came to the conclusion that the best joint arrangement is significantly influenced by the type of glue being used.

A Critical Comprehension of Effect of Surface Treatment on Physical and Mechanical Properties of Date Palm – Stem Fiber Embedded Epoxy Composites | Chapter 1 | New Ideas Concerning Science and Technology Vol. 6

Natural fiber-reinforced polymer composites are commonly used in a variety of engineering applications due to their outstanding characteristics such as low density, ease of procurement, and superior mechanical properties, but natural fibres are typically hydrophilic. An investigation into a type of natural fibre composite known as date palm-stem fibre composite was conducted in order to develop a new material with excellent water resistance properties that can be used in a variety of applications. Under the current study, the effect of loading date palm-stem fibre on physical and mechanical properties was studied, and appropriate efforts were made to investigate the surface treatment of short fibre based epoxy composites. The characteristics of the treated fibres were observed and compared to those of the untreated fibres. By using a simple hand lay-up technique, composites of various compositions with varying amounts of fibre loading were created, and it was discovered that the effect of fibre surface treatment on the overall properties of composites was quite important. Furthermore, date palm-stem and glass fiber-epoxy based hybrid composites had a lower water absorption rate.

Research on Strength, Fatigue Strength and Stiffness of High-Tech Bamboo/Epoxy Composites | Recent Advances in Science and Technology Research Vol. 2

A major problem in the strength data available for cellulose fibre‐based materials is that the moisture content of the test specimens is rarely measured, and yet it is the dominant variable in the tests. Detailed strength and stiffness results are presented for Brazilian Dendrocalamus Giganteus bamboo at a wide range of moisture contents down to 2% and the fatigue curve is given for Chinese Moso bamboo at 4% moisture content. Techniques are described for handling the variability of these natural materials, both in design and in manufacturing quality control, for the mass production of large, hightech composites wind turbine blades.
