Key Materials Shaping Modern Bikcles
Carbon Fiber: Thee Dominant High- Performance Choice
Carbon fiber composites consist of thin carbon filaments (typically 5- 10 microns in diameter) boud together bya polymer resin - usually epoxy. The fibers are woven into fabric sheets or oriented unidirectionally (unitary, or UD) to optimate stigness and districth along specific load paths. Layer bylayer, these sheets are stacked and caud undeid and presure to form a single, monothic structure.
