Solutions for even the most complex challenges
Autoclaving is process that operates at elevated temperature and pressure to consolidate plastic and fibers into a solid structure. Automated Dynamics manufactures structures using an autoclave based on the size, shape, and complexity of the part.
We have developed Advanced Fiber Placement Technology to make continuous carbon and glass fiber reinforced thermoplastic composites for extreme environments. These thermoplastics are reinforced with continuous carbon fiber, fiberglass and aramid reinforcement that consistently perform in aggressive environments of 350-600 degree temperatures with extreme pressure and a myriad of chemicals and solvents that typically corrode through metal.
A thin wall of material offline is pre-heated (above Tg but below the melt temperature), and then shuttled to a stamping station that has a mold in the shape of the desired product. The material is then pressed into the mold and the part is formed.
Raw material (a fiber reinforced thermoplastic) is placed inside a mold that is then brought above the materials' melt temperature. The mold is then compressed and the part is cooled and removed.
Automated Dynamics makes thermoset parts that have good chemical resistance, excellent mechanical strength, and excellent dimensional stability at certain temperatures. The fiber placement process requires a secondary curing operation that makes the finished part non-reformable.
The systems incorporated in our automated thermoset processes, including the elastomeric compaction roller, are so effective at achieving near net shapes that intermediate debulk steps are typically eliminated for even the thickest laminates. Consequently, fabrication time and manufacturing space are dramatically reduced, as compared with hand layup and other high touch labor intensive thermoset processing technologies.
