Fabrication fiberglass and articles thereof

The present application is a continuation-in-part of U. The present invention relates to fiber reinforced resin matrix composites, and more particularly, to an fiber reinforced composite spar for a rotary wing aircraft having enhanced structural properties, a method for facilitating the manufacture thereof and a spar forming apparatus useful in fabricating the composite spar. Typically, a leading edge sheath and trailing edge pocket assembly mount to and envelop the spar thereby yielding the desired airfoil contour. The spar typically extends the full length of the rotor blade and mounts at its inboard end to a cuff assembly or fitting which facilitates mounting to the hub member. Due to the extreme operational loading environment of the rotor blade, high strength, high density materials such as aluminum or titanium have, in the past, been the materials of choice for spar construction. More recently, however, fiber reinforced resin matrix composite materials, e.

In one embodiment, the metal-coated sheet material is impregnated with a resin. According to embodiments of the invention, a metal is applied to one or two sides of the fabric or veil by a physical vapor deposition coating process. Materials used in the fabrication of component parts in the aerospace industry must have certain characteristics to protect the parts from damage or hazards caused by common environmental occurrences. If lightning strikes a wing component of an aircraft during flight, the event has the potential of causing a dangerous surge current in addition to causing serious physical damage of the component itself. The surge current is particularly concerning because it may eventually come into contact with a fuel reservoir causing an explosion to occur. As a result of an actual fatal plane crash caused by a lightning strike, the Federal Aviation Administration FAA implemented a system to categorize various zones for commercial aircraft based on probability and severity of being struck by lightning.

This application is a divisional of U. Provisional Application Ser. The entire disclosures of U. The invention relates to a method for manufacturing a glass fiber reinforced article, and to a glass fiber reinforced article. Composite structures made from fiberglass material impregnated with a cured, thermoset resin are known for manufacturing articles such as spas, tubs, recreational vehicles, auto body panels, and marine components such as boat decks and hulls. The composite structures are sometimes referred to as fiberglass reinforced articles.

A purpose of the invention is to provide a material of the above description which is particularly adapted to the fabrication of antennas for sending and receiving radio and radar waves.

The invention belongs to the field of so-called technical fabrics, that is to say fabrics whose applications are mainly industrial. The invention more by-ticulibrement relates to a fabric based on fibers suitable for the manufacture of composite articles useful as external structures. At present, there is concern increasingly finding new lighter and stronger materials, even in very severe conditions. These technical problems are particularly crucial for the manufacture of external structures of aircraft, such as fairings, cowlings, doors and others. It is known that the field structure of an aircraft are subject to very wide temperature variations. They reach C in effect at altitude and sometimes go up to 70C on the ground. It is therefore endeavored to find the composite materials for the manufacture of such external parts, which are able to withstand such temperatures while possessing sufficient mechanical characteristics al-linked to a unit mass as low as possible. It is therefore a need to ensure the longevity and safety of outdoor structures, specia-bly aircraft, to develop materials free of such drawbacks, yet possessing properties at least equal to regard the unit mass General and mechanical properties. DSNs Ia technique for obtaining glass fibers, also referred to frayed glass fibers.

Thomas: In your letter, received November 2, , you requested a tariff classification ruling on behalf of Graboplan regarding fiberglass roofing panels. A sample of the material that comprises this merchandise was submitted with your ruling request. In your letter you indicated that the roofing panels consist of woven fiberglass coated with polytetrafluoroethylene PTFE. You stated that the products consist of approximately 60 percent woven fiberglass by weight and approximately 40 percent PTFE by weight. According to the information submitted with your ruling request, the fabricated fiberglass roofing panels are produced in Hungary using fiberglass fabric that had been shipped from the United States to Hungary. You suggested that the merchandise should be entitled to a partial duty exemption under subheading However, subheading Subheading In this instance, the processing of fiberglass fabric into fabricated roofing panels that takes place in Hungary is a substantial transformation.
