A complete demonstration of the Manufacturing Process of using Autoclave to produce carbon fiber auto parts the Autoclave Manufacturing Process ② Vacuuming Process. Measure the size and layup the peel ply on the top of the prepreg carbon fiber cloth. It has the benefit of leaving a very neat surface finish. the next layer into the mold is a breather cloth, this provides the air path for the air to escape under vacuum Prepare the vacuum bag with a reasonable size, and pre-sealed one side. Install the through bag connector, place, and seal into the vacuum bag. Connect it to the vacuum, as the vacuum is pulling down the bag should be manipulated into all of the contours and corners so that it conforms to the laminate without having to stretch. And the seal checked for leaks. Place the parts on the autoclave plate, and connect the vacuum one by one. Keep this on the vacuum around 12 hours, the preset temperature: 90-120 degrees, the part allowed to cure fully before demolding
