Editing Carbon Fiber Infusion

Carbon fiber can be found in the main structures of aircraft and spacecraft parts, racing car bodies, golf club shafts, bicycle frames, automobile springs and sailboat masts among many other uses. With its extremely high strength-to-weight ratio and rigid yet brittle properties, carbon fiber offers many applications.<br /><br />Vacuum Infusion (VI) is an economical and straightforward approach to laminating composite materials.

Unidirectional prepregs can be made more infusion-friendly by interleaving off-axis plies or adding an appropriate additive with flow enhancing capabilities.<br /><br />Temperature of resin is also key in the success of any VIP process. Warm resin has lower viscosity and flows much better than cold resins - particularly thermosets with an extremely fast gel time - making warm environments such as molds, dry stacks, and infusion bags the ideal environment for VIP production.<br /><br /><br /><br /><br /><br />
