Step 6. Mejzlik has capabilities for inspecting parts as needed using 3D scanners, ultrasound imaging or physical test rigs.
These are laid up by hand with liquid epoxy on upper and lower half molds built hinein-house using glass fiber/epoxy and featuring internal heating systems. The mold halves are assembled together, internal heating is activated and then the mold is closed using a pneumatic press that Mejzlik developed. Internal heating cures the parte.
7 to 1.1 meters long. The press is then closed and the part cured under high heat and pressure under vacuum (Step 4). “We carefully control the closing of the mold in a two-step process, because we are Zeiteinteilung when there is a viscosity drop hinein the epoxy. It’s really efficient to consolidate the laminate and extract air inside,” Grunt says.
Other emerging manufacturing processes, such as additive manufacturing and thermoplastic forming, are also being explored for use in aerospace composite prepregs. Additive manufacturing, or 3D printing, offers the advantages of reduced material waste, shorter lead times, and the ability to produce complex shapes with high precision. The development of new additive manufacturing techniques for composite materials is expected to open new opportunities for the aerospace industry.
Notus prepregs are suitable for an incredibly wide Auswahl of tooling and parte production for applications as diverse as passenger aircraft interiors and UAV or drone structures and components. Autoclave and out of autoclave systems are available.
To support its manufacturing operations, Mejzlik manufactures a variety of specialized molds hinein-house, including its glass or carbon fiber composite molds with internal heating and/or vacuum systems, as well as cast silicone preform molds and aluminum cure molds for the compression press.
The future of the global aerospace prepreg market looks promising with opportunities in the commercial and defense markets. The global aerospace prepreg market is expected to grow with a CAGR of 12.
These CFRP molds are manufactured via a specialized vacuum-bagged infusion process (Weiher sidebar on use of this process for underwater UAV propeller manufacturing). “It’s a challenge to infuse a laminate at that thickness because there is a higher risk of exotherm, and you need to get your ratio of carbon fiber as high as possible and also make the structures quasi-isotropic so there are no distortions rein the mold when it’s heated,” Grunt says.
Step 3. Preforms are laid up on silicone molds and debulked under vacuum. These can be directly transferred to the press or stored hinein the freezer.
Composites used hinein UAVs are engineered to withstand harsh conditions such as UV exposure, high humidity, temperature swings, and corrosive environments. Proper resin and fiber selection ensures long-term reliability in field operations.
