摘要： Vibration damping material in which polyvinyl chloride (PVC) and a particle filler such as fly ash or talc are amalgamated into a matrix by combination with a small percentage by weight of blown asphalt in a heat working process, such as extrusion, for forming a product such as a sheet of the material. By use of blown asphalt as a compatibilizer and amalgamator, waste or recycled PVC such as of electrical wire strippings combined with a filler has provided excellent damping characteristics.

摘要： A moldable sound control composite is disclosed combining in itself when molded damping, barrier performance, and structural strength for use within a predetermined environment temperature range. As such, the moldable composite is not applied to other structures to damp their sound generation, but forms by itself a complete structural member having not only desirable sound reducing properties but desirable strength properties as well. The composite comprises a blend of a primary non-viscoelastic organic polymeric resinuous material intended to impart structural strength to the composite, a secondary viscoelastic organic polymeric resinuous material to provide damping performance, and filler material adapted to densify the composite and impart barrier performance. Optionally, at least one of the primary and secondary resinuous materials may be thermosetting. By virtue of the blend of all of these ingredients, the molded composite has a glass transitional temperature range generally corresponding to the predetermined environmental temprature range for which the composite is designed for use and a maximum loss factor, n, falling within that range.

摘要： A syntactic structural foam product in flat sheet form or curved three-dimensional form adaptable to such uses as a light weight structural core for composite laminates, is made of a mixture of hollow ceramic microspheres and dry resin powder, of either thermosetting or a high-temperature thermoplastic resin, distributed in the interstices of the mass of microspheres for integration of the mixture into desired form upon heating and cooling. The dry resin powder in an other embodiment of the invention includes unexpanded expandable powder which will expand into microballoons in the confined spaces in which they reside and effect a bonding relation with surrounding particles upon supply of heat to the mixture. The foam product is produced by thoroughly intermixing and depositing the mixture as a layer over a surface having a release agent thereover within a dimension defined region and then supplying heat with or without pressure to the layer at a temperature and for a time period sufficient to effect a melting or softening of the resin powder and thereafter cooling the resin to a hardened condition to integrate the mixture into the product desired after which the product is withdrawn from the forming zone. Reinforcing elements such as glass or carbon fibers can be selectively included in the mixture for predeterminable desired physical and mechanical properties.
