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： In an apparatus and method for resin transfer molding, a mold including at least two cooperating mold sections is placed in a vacuum chamber. A reinforcing material is positioned between the mold sections, which are separated from one another during evacuation of the chamber, thus maintaining the reinforcing material in a substantially uncompressed condition, to ensure that all gasses and/or liquids are evacuated from the reinforcing material and the mold prior to resin injection. After evacuation, the mold sections are brought almost into engagement to substantially define a mold cavity, and resin is injected into the mold cavity. Prior to terminating the resin injection, the mold sections are brought into engagement, and final resin injection is performed. The injected resin is then cured in accordance with the particular type of resin injected.

摘要： It is possible to manufacture articles out of thermoplastic materials and to metallize the articles at their surface. In this way one can manufacture reflectors and similar articles. Most thermoplastic materials require extra processing steps prior to the metallization like application of primers, chemical etching and the like.The invention is based on the discovery that a certain type of materials can be metallized without any extra processing steps. The materials involved are polyestercarbonates or blends of polyestercarbonates and polycarbonate. This is quite surprising since polycarbonates can not be metallized in good quality without extra processing steps prior to the metallization step.

摘要： A method for producing advanced composite structures includes the assembly of a number of layers of fibrous reinforcements into a desired configuration. A vacuum is applied to the reinforcement in order to evacuate any air therefrom and to consolidate the plurality of fibrous reinforcements. Resin is introduced to the reinforcement by using a flow path therethrough having entry and exit points. The vacuum is used to transmit the resin through the reinforcement between the entry and exit points. The resin flows into the reinforcement due to the pressure differential between the evacuated reinforcement and the hydrostatic pressure on the resin as well as the capillary effect on the reinforcement.

摘要： An improved electrical insulator for high voltage transmission lines is formed from certain polymer-based concrete compositions. An apparatus provides for the molding of the polymer-based mixture to form a highly degassed product. The method and apparatus include the ability to combine the constituents of the mixture in a mixer. A vacuum is applied to the mixture to degas the mixture. A mold is filled with the degassed mixture without introducing air thereinto in the absence of a vacuum. The resulting insulator has highly reduced air entrainment.
