Advantages And Disadvantages Of Materials

For bio-composite, is a composite material formed by a “matrix” and “reinforcement” of natural fibers. These materials are often mimic the structure of the living materials involved in the process keeping the strengthening properties of

Carbon fiber in all aspects is a material consisting of thin fibers of nearly pure carbon made by subjecting various organic raw materials to high temperatures, combined with asynthetic resins to produce a strong, lightweight material use in construction of aircraft and spacecraft (dictionary 2016). This composite material dates back to the 1950s where the tensile strength of carbon fiber was discovered and put into work. 50 years later carbon fiber is still well used and in great demand as the benefits of it proved to be great for the race car industry. The purpose of this project is to examine the mechanical properties of carbon fiber, and the benefits that it provides to the race car industry as well as predicting what other applications will occur in the

Fibre glass, on the other hand, is made up of melted glass that is blown, elongated or extruded to for a string like material. Fibreglass has an advantage over carbon in that the synthetic manufacture of fibreglass is easier as it does not require high temperatures to be produced. The material, however, has nearly similar physical properties to carbon regarding strength, weight and modulus of elasticity.

Lead is a chemical element that is in the carbon group. The symbol is Pb and has an atomic number of 82. Lead can be used for weapons and cosmetics. However, there are advantages and disadvantages of using this element. A disadvantage is that if you are repeatedly exposed to this toxic element, it can cause anemia, brain damage and high blood pressure. An advantage is that lead has a low melting point, so it is easy to shape and mold the bullet.

The purpose of this lab was to learn about the different types of fibers and the distinguishing characteristics of used to identify them. Natural fibers and man-made fibers were examined in this lab. The fibers tested were part of a multi-fiber fabric with the following arrangement:

Composite materials have numerous features that led the automotive industry in using it in automobile designs. Its many key benefits include being lightweight, has high strength, corrosion resistant, chemical resistant, elastic, and non-conductive. Composite materials are extremely strong and are highly resistant to chemical, never having to rust or corrode. Fiber reinforced composites have excellent elastic properties. When composites are bent, they snap back into place. Fiberglass based composites are non-conductive.

Composites, is a material that made with two or more different material. People can see or use it anytime, anywhere. Composite materials can provide different advantages from mixing different materials, and usually combined metal (aluminum), polymers (epoxy) or ceramic (silicon). One of the most common example for the composites will be fishing rod. Nowadays fishing rod usually make with glass fiber/ carbon fiber and epoxy. Which glass fiber or carbon fiber are brittle but strong, and epoxy can provide a high mechanical properties. Result of the fishing rod can be have a better toughness, and lightweight. Because of that in this lab, the main objective is going to use the optical microscopy and find out the fiber’s alignment, the structure pattern and the mechanical properties from the fishing rod.

The objective of composite materials is to take advantage of the superior properties of both materials. Industry has identified the ability of composite material to produce high strength, high corrosive environment, and high durable as well as cost effective products.

To study the characteristic properties of hybrid fibrous ferrocement, the compressive strength specimens, flexural strength specimens, shear strength specimens and impact strength specimens were cast. For compressive strength test, specimens of dimensions 150×150×150 mm were cast. For flexural strength test, specimens of dimensions 100×100×500 mm were cast. For shear strength test, specimens of dimensions100mm×90mm×60mm (L-shaped specimens) were cast. The impact strength test specimens were of 150mm in diameter and 60mm thick. For impact strength test drop hammer was used (drop hammer weighs 4.5kg and falls from a height of 457mm). The number of blows required to cause the first crack and final failure were

Composites, the wonder materials are becoming an essential part of today’s materials due to their advantages such as low weight, corrosion resistance,

Composite materials are the engineering materials made from two or more constituent materials they remain separate and distinct on a macroscopic level but forming a single component or Composites can defined as materials that consist of two more chemically and physically different phases separated by a distinct interface(matrix phase and dispersed phase). The different systems are combined judiciously to achieve a component with more and more useful structural or functional properties non-attainable by any of the constituent alone. In the composites usually Matrix phase is the primary or base phase having a continuous character or continuous molecular chain. But these Matrixes are usually less hard and more ductile phase. In composites it holds the dispersed (reinforcing) phase, shares a load with it. The Dispersed phase is encapsulated in the matrix in a discontinuous form called a secondary phase. This Secondary phase is usually stronger than that of the matrix phase, so is also called as reinforcing phase.

Bio-materials are one of the most vital materials that are used in the medicine industry in recent times. These materials are basically classified under this class, since they perform or modify the natural function in an individual. These materials can be used on most of the living creatures with a few modifications.

Introduction: In order to conserve natural resources and economize energy, weight reduction has been the main focus of automobile manufacturers. Weight reduction can be achieved primarily by the introduction of better material, design optimization and better manufacturing processes. The achievement of weight reduction with adequate improvement of mechanical properties has made composite a very good replacement material for conventional steel. A composite is composed of a high performance fibers such as carbon, Kevlar, graphite or glass in a matrix material that when combined provides better properties compared with the individual materials by themselves. The composite materials are used in structural application areas, such as in aircraft, space, automotive, for sporting goods, and marine engineering. The various type of glass fibers available are Carbon fiber, C-glass, S-glass and E-glass. However, carbon epoxy material is better than other fibers but because of its high cost, it has limited applications. Favorable relation between cost and properties of a material can be obtained with E-glass fiber/epoxy.

This leads to reduction in the crack width and deflection in members subjected to flexure. Since the fibres only become effectively active after the crack formation, the inclusion of fibres in concrete alters the post cracking behaviour of normal concrete.

The fiber phase is usually made from materials that are usually stronger and have a higher modulus of elasticity than that of the matrix, but they are often very brittle [2]. Therefore, the matrix phase is usually the source of the composites’ ductility, whereas the fiber is the source of its strength.
