High-Strength Fiber Processing: A Detailed Guide

Wiki Article

Fabricating carbon composite parts involves a complex series of steps, beginning with the raw material . Typically, this material is PAN , which is drawn into fine filaments. These strands are then heated at high temperatures to improve their heat resistance, followed by carbonization in an non-reactive atmosphere. This pyrolysis process changes the plastic structure into nearly pure carbon. Subsequently, the resulting carbon filaments are often sized with a coupling agent to improve their bonding to a resin material, typically an epoxy resin, during the final component creation. The ultimate step includes different methods like layup and curing to achieve the desired geometry and physical properties.
