The vacuum technology

During carbon laminates production it’s very important to pay attention to air inclusions into the epoxy resin that impregnates the fabric. Air bubbles that are naturally formed during the resin and hardener mixing can remain trapped into laminate at the end of the production cycle and they can cause a lot of troubles:

• Crack propagation into laminate
• Loss of mechanical properties
• Contaminating agents inclusion
• Loss of aesthetics properties

In order to avoid air inclusions it’s necessary to vacuum the laminate at the end of impregnation phase with epoxy resin. The vacuum eliminates the most of the air inclusions, also the superficial ones that damage the product aesthetics. The laminate is sealed with a special PE (Polyethylene) bag in which we put an air intake valve linked to a vacuum pump.
