outofautoclavehärdning

Out of autoclave (OOA) hardening is a composite material manufacturing process that involves the use of a chemical catalyst to cure a resin inside a vacuum bag. The process is also known as wet handling, as opposed to the more traditional dry bag molding process. The OOA hardening process involves the use of a vacuum bag to hold the resin in place, allowing it to cure in a controlled environment.

The OOA hardening process offers several advantages, including reduced shrinkage and improved dimensional accuracy. The use of a vacuum bag also allows for the removal of trapped air, which can lead to defects in the finished product. Additionally, the OOA process can be used to create complex geometries and thin sections, making it suitable for a wide range of applications.

The OOA hardening process typically involves the use of a combination of prepregs, a primer, and a epoxy or polyurethane resin. The prepregs are typically made from a combination of reinforcing fibers and a thermoset resin. The primer is applied to the surface of the mold or insert, before the prepregs are placed inside the vacuum bag. The resin is then cured in the vacuum chamber, under carefully controlled temperature and pressure conditions.

OOA hardening is widely used in the aerospace industry, particularly for the production of composite components such as wing skins and ribs. The process is also used in the production of sports equipment, automotive parts, and other high-performance applications.
