Autoclaves use a very precise combination of heat, pressure, and vacuum to transform the prepreg materials into very strong and sturdy parts. These machines use Nitrogen as it is an inert gas therefore not promoting combustion within the Autoclave cure process. During the curing process, the pressure of up to 10 bars is applied under a temperature ramp-up of up to 250 degrees centigrade for approximately six hours.
Strata’s four 5-Axis CNC Machines (Computer Numerical Control) is responsible for the trimming of all products down to the specifications called for by the customer. These machines are capable of cutting up to 65 meters per minute and are accurate to 0.02mm, the average thickness of human hair.
Non-Destructive Testing (NDT) is used to confirm the Quality and conformity of the bonded products produced in the CCA. Methods in use include A-Scan, 3 axis C-Scan, 10 Axis C scan, X-Ray, and manual tap testing. In this process Strata can determine the quality of the products, meeting the standards set by the customers’ specifications.
