Pressurex® Film Placed Between Composite Layup Rollers
Pressurex® is a unique, affordable and easy to use tool that reveals the distribution and magnitude of surface contact pressure in your prepreg rollers and composites lamination press.
Pressurex® sensor film reveals both pressure distribution and magnitude between contacting surfaces in a dramatic surface “map.”
When placed in your nip rollers or platens of your lamination press, Pressurex® instantaneously and permanently changes color in direct proportion to the pressure being applied. Conceptually similar to Litmus paper, the color Pressurex® turns reveals the precise PSI level.
Have you ever needed to evaluate pressure or force between two touching or mating surfaces? Previously, your only alternatives were strain gauges and load cells, that are both time consuming and difficult to interface. Now with the advent of our disposable one-time use pressure film, Pressurex®, evaluating surface contact pressure distribution and magnitude is accurate, quick and highly economical.
Benefits
• Properly align rollers to ensure uniform resin application and fabric wet-out.• Detect and correct lamination press uniformity issues to reduce off-spec fiber content.
• Prevent defects such as resin content inconsistency in the resin metering stage.
