Rohacell® Wing Sections for UAVs
Rohacell® (polymethacrylimide ) structural foam is extensively used in the aerospace, marine, automotive and medical industries offering lightweight machined parts. Pronat offers comprehensive manufacturing capabilies to produce core structures up to 2.6M wide. In addition, we have suitable heating ovens and measuring devices to ensure consistent quality production. There are various Rohacell® grades available designed for specific applications, some of these are shown below.
Nomex® Honeycomb sheet
DuPont™ Nomex® honeycomb composites helps to provide lightweight strength, stiffness, toughness, corrosion resistance, which bring high value-in-use to industries such as mass transportation, aerospace, construction, and marine shipping. For more than 30 years, the transportation industry has embraced Nomex® honeycomb composite made with DuPont™ Nomex® for its excellent strength-to-weight ratio, which assists to provide vital cost-effective benefits like energy savings and payload increases. Stiff, thin Nomex® sheet structures are used to help make strong, yet lightweight, honeycomb sandwich composite found in aircraft parts such flooring panels, interior walls, storage bins, exterior control surfaces, engine nacelles, and helicopter blades and tail booms. Nomex® honeycomb composites are also used in the construction of boats to help provide buoyancy that enhances speed.
Composite & Pre-preg Materials
Pre-preg is a term for “pre-impregnated” composite fibers where a matrix material, such as epoxy, is already present. The fibers can take the form of a weave or non-woven and the matrix is used to bond them together. The matrix is only partially cured to allow easy handling, this B-Stage material requires cold storage to prevent complete curing. B-Stage pre-preg is always stored in cooled areas since heat accelerates complete polymerization. Composite structures built of pre-pregs will mostly require an oven or autoclave to cure.
Pronat has evolved several processing capabilities using composite materials including, bias sewing panels, and cutting and chopping coated B-stage fabrics from standard roll.
Graphite Wing & Frame Sections
Graphite sheet is used in the production of UAV panels and wings where additional mechanical strength is required.
Aircraft Window Stripping Masks
Paint removal masks are designed with pressure sensitive aluminum foil to safeguard aircraft windows by forming an impenetrable barrier against chemical stripping agents. To protect windows from paint overspray, these masks are made with aluminum, paper and crepe masking tape capable of withstanding temperatures up to 250°F. Stripping masks are pre-cut to window sizes with die-cut backing. Pressure sensitive adhesive provides holding strength without leaving any residue after use. Standard profile shapes are available for various aircraft including Airbus A320, Boeing 737, ATR 72 etc.
