Diab Flow finishing options - grooved & perforated sheets
To distribute resin and evacuate air, there are several options. Diab has developed unique solutions especially suited to the needs of fast and secure vacuum-assisted manufacturing, so you can get the best performance out of every design.
Cuts or shallow grooves on the core surface will allow the resin to distribute and ensure good laminate wet-out. Perforations allow air evacuation, and in a vacuum infusion process, the perforations will transfer resin from one side of the core to the other, further ensuring proper laminate wet-out. Perforations are also used when working with prepreg, or when using core bedding adhesives. These finishes can be successfully combined with formable options.
Grooved and perforated combinations remove the need for an additional distribution medium within the laminate or above it. These finishes can be successfully combined with formable options such as grid-scored material.
Selecting the right finishing will impact not only the weight of the final component and surface quality, but can also speed up manufacturing time.
Diab will help you select the most efficient flow finishing based on your specific requirements.
