Relative Shock Absorbency of Different Materials
The term shock absorbency could be used when referring to a materials ability to absorb energy from shocks and impacts. This ability to absorb energy is known as its relative shock absorbency. Depending on the material it can be used for different purposes. In this article, we will explore the relative shock absorbency of different materials.
The most obvious use of materials with a high relative shock absorbency is in the production of sports equipment, as this can reduce the risk of injury. Soft rubber, foam and plastic materials, for example, are commonly used as they have the ability to absorb more impact energy than rigid materials, significantly reducing the risk of serious injuries. In addition to this, soft material may also have a greater deformation rate, allowing them to better absorb energy in the event of a collision.
Foam materials, such as expanded polystyrene and polyurethane foam, are widely used for shock absorption. Expanded polystyrene is a material made up of tiny molecules linked together to create a cellular structure. The air pockets within the material allow it to absorb energy from an impact, significantly reducing the risk of injury when someone falls on it. Polyurethane foam, on the other hand, is a denser, flexible material, making it ideal for cushioning and protecting against impacts.
Another type of material that has a high shock absorbency rating is metal. Certain metal alloys such as aluminum are incredibly strong and durable, but their cellular structure makes them incredibly flexible, allowing them to absorb energy from shocks and impacts. This makes them particularly useful in the aerospace industry, where theyre commonly used to construct aircraft frames and components.
Similarly, certain composite materials, such as carbon fiber and Kevlar, can be used to create components that are light and resistant to shock whilst being able to absorb an impact. The combination of the high strength and shock absorbency of these materials make them the perfect choice for a wide range of applications, from Olympic athletics to Formula 1 racing.
Ultimately, the choice of which material to use depends on the application. In general, softer materials have a greater shock absorbency than rigid materials, but this is not always the case. Each material has its own unique properties and it is important to consider how the properties can benefit the product or application before selecting the specific material. By doing this, it will be possible to find the best material for the desired purpose.
