Creative Composites Group specializes in vacuum infusion, the most cost-effective method for molding large structural parts, including boat hulls, wind turbine blades and bridges.
There are 5 steps to the vacuum infusion process:
During the process, dry fiber materials are placed into a shaped mold and covered with a sealing plastic. Once the reinforcement materials are under complete vacuum conditions, precisely positioned tubes introduce liquid polymer resin into the mold. The vacuum comes into play to drive resin throughout the fiberglass reinforcements. Though more time-consuming than other methods, vacuum infusion is a more customizable process that creates a maximum fiber-to-resin ratio. and produce large, high-strength FRP panels.
With the vacuum infusion process, resulting products are both stronger and lighter thanks to the improved fiber-to-resin ratio.
Other key benefits include:
Vacuum infusion is also highly controllable, as only three variables affect the resin flow: the permeability of the laminate, the pressure differential in the cavity in relation to atmospheric pressure; and the viscosity of the resin.
Compared to other closed mold techniques, vacuum infusion involves higher consumable costs and slower cycle times. But for large parts, the advantages are clear.
