Carbon Fiber: New Technologies For Better Bicycles
Thought of as an exotic space-shuttle composite just a decade ago, carbon fiber is now used in pretty much every cycle component, from frames and parts to helmets and shoe soles. Carbon fibers are made from carbon, the ever-present component that forms coal, graphite and diamond and is a component of every organic chemical and every life form on earth. Carbon is the 4th commonest element in the universe and the
2nd most common element in the body.
Polyacrylonitrile ( PAN ) fiber, also the source material for acrylic fiber, is made into carbon fiber by heating it to extreme temperatures, burning away fundamentally everything aside from carbon. The ensuing 5-8 micron ( millionths of a meter ) thick fibers are a tenth the thickness of a human hair and made from carbon atoms strongly bonded together in minute crystals aligned parallel to the fibers axis. Strong and stiff, the fibers have a stiffness index of thirty three million pounds per square in. ( MSI ) and a rough surface. Dear processing can strip off this outer surface to reveal a thinner, smoother
Intermediate Modulus ( IM ) fiber that packs tighter with other fibers for higher stiffness per unit area. A costlier processing can create High Modulus ( HM ) carbon fibers, which boasts a Youngs modulus stiffness of 42 MSI to 55 MSI or more.
Common-modulus fibers are wrapped up together into yarn and woven into fabric. A number followed by the letter K designates how many thousands of fibers are in a strand of the yarn ( as in 3K, for three thousand fibers per strand ). Woven fabric frequently comprises the top layer for classy purposes, but most carbon fibers in a bicycle part instead come in flat sheets of tightly packed parallel fibers pre-impregnated with epoxy resin stuck to backing paper. Exactly cut pieces ( plies ) are stacked, or laid up, on top of each other at opposing angles ( sometimes 45 degrees ), to fight forces from different directions. Unlike metals, carbon fiber plies within the laminate structure can be oriented to form a composite structure that can be stiff in one direction and more
Flexible in another. Indeed, plies must be laid up at angles, because carbon fiber, like thread, is strong if you pull on it but far weaker if you push lengthwise on it or bend it sideways. However , in a carbon fiber tire bead, you do not need strength in stress alone, so orienting fibers at angles and gluing them along with resin permits the plies to work together, opposing forces from all directions. Subjecting the laminate to high pressure and heat in a mold pushes out air and excess resin.
Well-engineered carbon composite parts have high stiffness and strength, low density and high fatigue life but low elongation they can't stretch or bend much before they break. Disasters come from not properly engineering the directions and types of fibers to handle the loads.

Crankset $81.25 The crankset, or chainset, is the component of a bicycle drivetrain that converts the reciprocating motion of the riders legs into rotational motion used to drive the chain, which in turn drives the rear wheel. It consists of one or more sprockets, also called chainrings or chainwheels attached to the cranks or arms to which the pedals attach. It is connected to the rider by the pedals, to the bicycle frame by the bottom bracket, and to the rear sprocket, cassette or freewheel via the chain.
