Radiocarbon dating also referred to as carbon dating or carbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon , a radioactive isotope of carbon. The method was developed in the late s at the University of Chicago by Willard Libby , who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen.

What is Carbon Dating?

A carbon bike frame is a matrix of two different materials: the carbon fibres which give the frame its structural strength, and the resin which binds the carbon together. Carbon frames are well able to withstand the day-to-day flexion required to negotiate bumpy roads. But a more major shock such as a crash needs specialist examination, while over-tightening bolts can also lead to damage. Internal damage to frame tubes may not immediately be evident and carbon repairers will use specialist techniques such as ultrasound and X-rays to identify deeper damage. The carbon fibres used are very strong, but the resin needed to hold them together is potentially susceptible to degradation over time.
