Carbon-Fibre-Reinforced Polymer (CFRP)

Good Essays
Carbon-fiber-reinforced-polymer (CFRP) is a composite polymer made up of carbon fibers and a binding polymer. The binding polymer can be a thermoset resin or thermoplastic polymer(s). Examples of thermoplastic polymers that can bind with carbon fiber to make CFRP are polyester, nylon, or vinyl ester. A thermoset resin that can combine with the carbon fiber to make CFRP is epoxy. The combination of the carbon fibers and a thermoset resin or thermoplastic polymer producing CFRP results in a light weight fiber-reinforced plastic that is tremendously strong. Depending on the binding polymer, CFPRs have a wide range of applications and are used when a light weight material with high rigidity and strength are required. Carbon fibers were discovered in the late 1800s by Thomas Edison. The early lightbulbs Edison created used the carbon fibers as filaments. These carbon fibers used to create the early lightbulbs had a substantial tolerance to heat, but they lacked the tensile strength of modern carbon fibers. Edison used cellulose-based materials, such as cotton or bamboo, to make his carbon fibers. He used a method called “pyrolysis” to cook the bamboo at high temperatures in a controlled atmosphere to carbonize bamboo filaments, making them fire-resistant and capable of enduring intense heat needed for luminescence. The most important component of a CFRP is the polymer it is combined with.…show more content…
It is used in aerospace engineering, automotive engineering, civil engineering, and sporting goods. Aerospace engineering utilizes CFPR for the strength and lightweight properties. The Airbus A350 XWB has the highest weight ratio for CFRP at 52%. This includes wing spars and fuselage components. This is one of the first commercial aircrafts to have a structural composite components, the utilization of CFRP has helped optimize aerodynamic efficiency. Using CFRP is a fairly new transition from metallic
