An apparatus () that houses functional components of a mechanical assembly includes a frame component () formed of a first material, the frame component () bearing primary load, torque or pressure applied to the apparatus () during operation of said mechanical assembly. The housing apparatus () further includes a composite reinforcement component () for resisting forces applied to the apparatus during operation of the mechanical assembly and an enclosure component () formed of a second material of lower density than the first material of the frame component (), the enclosure component () covering and sealing at least the functional components of the mechanical assembly from external conditions during operation of the mechanical assembly.

Mechanical assembly housing

Housings for electrical or electronic components made using braid or woven fabric sheets having multiple sections treated with different materials as well as processes and materials for making such housings are disclosed.

Housings for electronic components

Injection molding systems and methods useful for making microcellular foamed materials are provided as well as microcellular articles. Pressure drop rate and shear rate are important features in some embodiments, and the invention provides systems for controlling these parameters in an injection molding system. Another aspect involves an injection molding system including a nucleator that is upstream of a pressurized mold. Another aspect involves an extrusion system with the reciprocating screw for forming a single phase solution of non-nucleated blowing agent and polymeric material. Another aspect involves very thin walled microcellular material and very thin walled polymeric material. Another aspect provides a method for producing high weight reductions in very thin-walled parts with surfaces that have no noticeable differences from non-foamed parts.

Injection molding of polymeric material

An aircraft wheel () comprises a metal support structure () having a first annular ring () and a second annular ring () connected via at least one connecting element (); and a fiber-enforced, molded-composite body. The metal support structure () is at least partially embedded in the composite body to form a first aircraft wheel section () having a rim flange () for forming a seal with a tire.

Hybrid aircraft wheel comprising metal and composite portions

A fiber-based acoustic treatment material is provided. The material includes between about 3% and about 25% by weight of fibrillated microfibers, between about 20% and about 75% by weight of reinforcement microfibers, and between about 15% and about 60% by weight of a binder. Methods of making the material are also provided.

Methods and apparatus are provided for making a fireproof panel. The fireproof panel includes a first ply of material and a ceramic material impregnating at least a portion of the first ply of material, the ceramic material formulated to resist loss of physical properties when exposed to temperatures of at least 1090&#xb0; C.

Fireproof panels and methods of fabricating the same

An avionics chassis for protecting against damage, dust, dirt and incidental moisture over an extended temperature range, EMI shielding to prevent radiation of internal circuit energy and preventing the entrance of external EMI. The chassis provides lower weight, lower levels of radiated emissions and improved resistance to incident external radiation. Electric and magnetic shielding is also provided.

Composite avionics chassis

An integrated noise suppression acoustic panel includes a back plate, a face plate, and a bulk foam absorber disposed between the back plate and the face plate. The bulk foam absorber is formed of a thermoset material, such as bismaleimide or phenolic, and is manufactured using a low pressure process. In particular, a foamable material is melted, and a blowing agent is mixed with the foamable material to obtain a mixture. The foam is formed and the mixture is cured by heating it to a temperature, and maintaining the mixture at the temperature for a time sufficient to cure the mixture.

Continuous polymeric extrusion nucleation systems and methods useful for making polymeric microcellular foamed materials, including crystalline and semi-crystalline polymeric microcellular materials, are provided. Pressure drop rate is an important feature in some embodiments, and the invention provides systems for controlling these and other parameters. One aspect involves a multiple-pathway nucleator that is separated from a shaping die by a residence chamber. Another aspect involves a die for making advantageously thick articles, including a multiple-pathway nucleation section. Microcellular material can be continuously extruded onto wire, resulting in a very thin, essentially closed-cell microcellular insulating coating secured to a wire. Other very thin microcellular products can be fabricated as well.

Method and apparatus for microcellular polymer extrusion

A process for adjusting the level of water or water soluble additives in aqueous-based powder injection molding compounds for the purpose of recycling scrap material, controlling shrinkage or rehydrating dry feedstock. Depending on the objective, the process may require material granulation equipment, equipment for the addition or removal of water and mixing equipment. The molding compounds may be comprised of either recycled scrap material before being heat-treated or dry, virgin feedstock material.

Multifunctional laminate structure and process

A slipper bushing assembly including a series of concentric members for permitting controlled sliding movement between a support element and a movable element. The concentric members of the slipper bushing assembly include a rigid one piece inner metal member joined to the support element, a hollow cylindrical elastomeric member, a rigid, one piece hollow outer metal member, a solid slip surface and structure for preventing the inner metal member from disengaging from the outer metal member. The inner metal member has a pair of opposing ends and an outer cylindrical-like surface. The elastomeric member encircles the outer surface of the inner metal member and has a pair of opposing ends, an outer surface and an inner surface. The outer metal member is joined to the movable element and has a pair of opposing ends and an outer cylindrical surface. The slip surface is contiguous to the inner or outer surface of the elastomeric member and coextensive therewith.
