  • Patent number: 9676148
    Abstract: A system and method for temporarily sealing holes in a perforated material layer of a composite acoustic panel so as to reduce potential migration of a release agent through the holes during a curing process and to reduce ingression of water through the holes during a subsequent testing process. The release agent is applied to a tool, the barrier layer is arranged over the release agent, and a lay-up of elements, beginning with the perforated layer, are arranged over the barrier layer prior to heating the lay-up to form the panel. The barrier layer may be a substantially solid film, such as a plastic or nylon film, having a width of at least approximately twelve inches and a low vapor permeability with regard to the release agent. After the testing process is complete, the barrier layer may be peeled from the panel.

This body is obtained by a method of densifying a porous silicon carbide substrate that includes the steps of impregnating a porous silicon carbide substrate with a curable silicone composition that contains a silicon carbide powder, curing the silicone composition, and thermally decomposing the cured product in a non-oxidizing atmosphere. The porous silicon carbide substrate can be densified and improved easily.

  • Patent number: 8216668
    Abstract: The present invention provides a resin composition which can produce a multilayer printed wiring board not causing peeling and crack in a thermal shock test such as a cooling/heating cycle, and having high heat resistance and low-thermal expansion characteristics, when the resin composition is used for an insulating layer of the multilayer printed wiring board; and also an insulating sheet provided on a base, a prepreg, a multilayer printed wiring board and a semiconductor device using thereof. The resin composition is used for forming an insulating layer of the multilayer printed wiring board, wherein a surface roughness parameter Rvk value of the insulating layer is from 0.1 ?m to 0.8 ?m, measured after the insulating layer being formed with the resin composition, and subject to roughening treatment.

    Abstract: An article comprises one or more porous particles. Each porous particle comprises a polymer that provides a continuous solid phase including an external particle surface, and first and second discrete pores that are isolated from each other and dispersed within the continuous solid phase. The porous particle further comprises a first marker material present in the first discrete pores, and a second marker material that is detectably different from the first marker material and is present within the second discrete pores. The marker materials can provide a means for identifying documents, clothing, or other articles as genuine, and providing a detectable security system.

  • Publication number: 20120052284
    Abstract: A resin composition that is storable at ambient temperatures. The resin composition forms a cured resin when exposed to a curing agent and heated to a curing temperature that is relatively close to ambient temperature. The resin composition includes a resin component that is composed of a liquid part that is made up of one or more liquid thermosetting resins and a solid part that includes particles of one or more solid thermosetting resins. The liquid part further includes a gelation agent that is present in a sufficient amount to maintain the particles in suspension within the liquid part at ambient temperatures. The viscosity of the resin component changes from a high viscosity state to a low viscosity state when the temperature is increased from ambient temperature to the curing temperature. The high viscosity state is substantially more viscous than the low viscosity state.

  • Publication number: 20120009391
    Abstract: A system for self-repairing matrices such as concrete or cementitous matrices, polymeric matrices, and/or fibrous matrices, including laminates thereof. The system includes repair agents retained in and/or on vessels, such as hollow fibers, within the matrix. Upon impact, the vessel rupture, releasing the chemicals. For multi-layer laminates, the systems provides a total dynamic energetic circulation system that functions as an in situ fluidic system in at least one layer or area. The energy from the impact ruptures the vessels to release the chemical(s), and mixes the chemical(s) and pushes the chemical(s) and/or resulting compound through the matrix. The repair agents can withstand high temperatures, such as the heat of processing of many laminates, e.g., 250-350° F.
