It\u2019s never actually pure carbon – It is a composite material<\/p>\n

Low Modulus carbon fibres are recognised as the most common and cost effective fibres to produce, these are less stiff but strong once laid up with epoxy and cured. Whereas High Modulus carbon fibres will produce a part which is much stiffer, but not quite as strong.<\/p>\n

Carbon fibres start from some sort of polymer \u2013 which is essentially just a long chain of carbon atoms with other elements, such as hydrogen and oxygen, poking off the sides. The polymer is then heat-treated at very high temperatures.<\/p>\n
This process removes all of those oxygen and hydrogen atoms and what you\u2019re left with are the carbon atoms which have a very good bond strength<\/p>\n
It\u2019s this heat-treating process that determines whether a carbon fibre is high modulus or low modulus. The higher the temperature and the longer you heat treat it, will make the fibre even more pure and have a better carbon crystalline structure. This gives the carbon a higher modulus but with the temperatures and lengthy heat treating process, it\u2019s also more costly.<\/p>\n
When talking about carbon frames, it\u2019s never actually pure carbon – it is a composite material, with resins to bond the carbon fibres together.<\/p>\n
Manufacturers might use more standard and intermediate [i.e. lower modulus] fibres in high strength areas of the frame, giving the most optimised stiffness, strength and weight in the final product.<\/p>\n
So a wide range of high modulus, intermediate modulus fibres and sometimes standard modulus fibres are used in all carbon bikes, and it\u2019s all about putting the high stiffness and high strength fibres where they\u2019re needed most. We usually see a combination of different carbon fibres that are used in most high-end branded frames because they are trying to optimise those characteristics of strength and stiffness.<\/p>\n
It is never a simple subject but hopefully you can understand a bit more when someone tries to bamboozel you with jargon!<\/p>\n
