摘要： A process and apparatus for producing perforated composite structures, such as acoustic skins suitable for aircraft engine nacelle and duct components. The process includes placing a mat member, a non-impregnated fabric member, and a resin film on a tool surface so that pins disposed on the mat member project through the fabric member and resin film to define holes therein. The fabric member is between the mat member and resin film, and the fabric member and resin film define a stack that conforms to the mat member and tool surface. A caul member is then placed on the stack so that apertures in the caul member are penetrated by the pins. The stack is heated to melt the resin film and cause molten resin to infuse the fabric member and yield a resin-infused fabric stack, after which the molten resin within the resin-infused fabric stack is at least partially cured.

摘要： Processes for fabricating polymer composite materials that contain a polymer matrix, reinforcement fabrics, and particles of a filler material. The processes include spraying the particles of the filler material on at least two articles that each comprise at least one of the reinforcement fabrics to form particle-laden articles. The particle-laden articles are stacked to form a stacked structure, and a resin present within the stacked structure is then cured to form a laminate polymer composite material. The process can be employed in the fabrication of at least a portion of an aircraft engine nacelle, for example, the inlet lip of a fan nacelle.

摘要： An inflatable restraint, and method of using the same, is used to provide support and shock isolation for missiles, torpedoes, missile canisters or the like in naval vessels. The inflatable restraint features a structural collar, at least one inflatable bladder and at least one interference member. The interference member is attached to the inside of the structural collar and the interference member is fully adjustable to ensure a snug fit during the loading of the missile, torpedo or missile canister into the structural collar. Once the missile, torpedo, missile canister or the like is properly inserted into the structural collar, the at least one inflatable bladder, which is also attached to the inside of the structural collar, is inflated to restrain the object. The pressure of the inflatable bladder may be regulated to provide variable spring constants and stiffness.

摘要： A sheet of uncured polymer, which is preferably reinforced with multiple layers of fiber, is staged or partially cured to a state in which the sheet is rigid at room temperature. Multiple apertures are drilled into, and preferably through, the sheet. The apertures are for acoustic or laminar flow control, and include holes having diameters in the range of 0.025 to 0.120 inch. In the case in which the fabricated panels must conform to a particular shape, the perforated, partially cured panels are heated to a temperature at which the panel softens, and conformed to the desired surface. The partially cured, perforated sheets are then cured. In order to prevent closure of the drilled holes during the cure, the perforated panel is sandwiched between two layers of glass fabric and cured on an elastomeric tool surface which expands with increases in temperature, forcing the glass fabric to seal the holes during cure. Release coatings are used to aid panel/liner separation.

摘要： In a laminated structure, such as a structural component of an aerospace vehicle or the like, which is fabricated of layers of filament composite material, means is provided for protection against lightning strike damage and electromagnetic interference. In particular, the outer surface layer of the filament composite material is fabricated of conductive metallic-coated filaments to provide a conductive barrier to disperse the current from lightning or other electromagnetic sources. The filaments may be fabricated of a composite material such as glass which has an aluminum coating. The structure may be woven or filament wound with intermixed resin, and the metallic-coated filaments are cured simultaneously with the entire laminated structure of filament composite material.
