Diab finishing options - Grooved & perforated sheets
Using a plain sheet is the most effective way to utilize a core. Through machining, it can be perforated, grooved or slitted to make it as functional as possible for the application. To distribute resin, there are several options.
Perforations (PFC) avoid air from being trapped under the core, ensuring proper wet-out and bonding to the laminate. Perforated materials are commonly used when doing hand lay-up, vacuum bagging or when using core bedding adhesives. In an infusion process, the perforations will transfer resin from one side of the core to the other.
Grooved and perforated cores (GRC, GRV, GPC) remove the need for additional distribution medium within the laminate or above it. These finishes can be successfully combined with formable options such as grid-scored or double cut.
