The amount of load that it takes to break a piece of fibre glass depends on the size of the piece of fibreglass, its thickness, width and length, whether we are simply pulling it in tension, compressing it, or bending it. So I will start by asking a simple question, 'How strong is a piece of fibreglass?вЂќ As you should be aware, there is no single answer to that question and one might be tempted to reply, 'How strong do you want it to be?вЂќ Perhaps the easiest way to demonstrate how the design process required to develop a composite material is implemented is to start with a familiar composite material and examine just what factors control its properties. It is one of the goals of this resource to show you the logical steps needed to implement the design process. So the composite must offer a specific advantage in terms of cost or performance than conventional alternatives. We should also keep in mind that there may be an exisitng conventional material that is more suitable for the application than a composite. As in all design processes, it may not be possible to meet all the specifications exactly and compromise and trade offs will be required, but by understanding the physical origin of the required properties and developing an appropriate mathematical description, a suitable composite can be designed. Whatever the specifications it should be possible to design a suitable composite material. Those attributes might be as simple has having a specified stiffness and strength, a desired thermal conductivity, or have a minimum specified stiffness at the cheapest possible cost per unit volume. So, 'Yes', it is possible to design a composite material such that it has the attributes desired for a specific application. Secondly, the appropriate physical and mathematical models that describe how the properties of the individual components of the composite are combined to produce the properties of the composite material itself must be derived. Obviously the answer to that question is 'Yes'! First, we must identify the numerous materials related variables that contribute to the mechanical and physical properties of the composite material. Is it possible to design a composite material? Regardless of the actual composite, the two constituent materials that make up the composite are always readily distinguished when the material is sectioned or broken.

There are many composite materials and while we may be aware of some, such a fibreglass and carbon epoxy, there are many others ranging from the mundane, reinforced concrete ( a mixture of steel rod and concrete (itself a composite of rock particles and cement), pneumatic tyres ( steel wires in vulcanised rubber), many cheap plastic moldings (polyurethane resin filled with ceramic particles such as chalk and talc) to the exotic metal matrix composites used in the space program (metallic titanium alloys reinforced with SiC ceramic fibres), and your automobile, such as engine pistons (aluminium alloys filled with fibrous alumina) and brake discs (aluminum alloys loaded with wear resistant SiC particles). After making the brass by melting the copper and zinc together and solidifying the resultant mixture, it is impossible to distinguish either between or where the atoms of copper and zinc are. An example of an alloy that most people are familiar with is brass, which is made from a mixture of copper and zinc. This is not the same as making an alloy by mixing two distinct materials together where the individual components become indistinguishable. If one were to cut the fibreglass and, after suitable preparation of the surface, look at the material, the glass fibres and polymer resin would be easy to distinguish. The most common example is, perhaps, fibreglass, in which glass fibres are mixed with a polymeric resin.
