摘要： Polymeric materials and products, including sheet flooring materials prepared from the polymeric materials, and processes for preparing the polymeric materials, are disclosed. The polymeric materials include a polylactic acid-based polymer in combination with plasticizer and a compatibilizer, and optionally include a filler. The polymeric material can include between about 30 to about 50 percent by weight polyvinyl chloride, polyethylene glycol, polyglycolide, ethylene vinyl acetate, polycarbonate, polycaprolactone, polyhydroxyalkanoates, or polyolefins modified with polar groups, for example, ionomers. The plasticizer is typically an epoxidized vegetable oil or esterified and epoxidized vegetable oil and is typically present in an amount of between about 10 and about 50% by weight. In some embodiments, the compatibilizer is a polyolefin modified with one or more polar functional groups, and is typically present in an amount of between about 5 and about 10% by weight. The material can be used in decorative surface coverings, such as a floor coverings, particularly when it is in the form of a polymeric sheet. The polymeric material can be present in at least one layer of a floor covering, which floor covering can also include one or more additional layers such as wear layers, foamed or foamable layers, top coat layers and design layers. The additional layers can also include the polymeric material.

摘要： A method using irradiation with optical light having a wavelength of 160 to 500 nanometers without higher wavelengths with cooling of the surface during the irradiation to modify the surface (12A, 104A, 202A, 304A, 402A, 502A) of a substrate (12, 104, 202, 304, 402, 502) is described. The light is filtered or the lamp (24, 106, 212, 306, 510) is restricted to the limited range to avoid the affects of the higher spectra. The light can be pulsed or continuous. The method is significantly enhanced by the presence of water (14, 124, 204, 306, 410, 508) on the surface, preferably also in the presence of ozone in the water. The treated surfaces are more paintable and bondable.

摘要： A method and apparatus for aligning discontinuous fibers (F 101, 212) is described. A feeder apparatus (20, 120, 220, 220A) is used to align the fibers in a horizontal plane for feeding to the aligning apparatus (40, 140, 240, 240A) providing an electrical (E) field to orient the fibers in one preselected direction. A support or conveyor (70, 170, 270) receives the aligned fibers. The method and apparatus provides composite products having improved physical properties because of the alignment. The fibers can be of different lengths and a mixture of different types to make composites with controlled microstructure and properties. The composite materials can be in the form of non-woven, discontinuous fiber reinforced thermoplastic stampable sheets with controlled fiber orientation distribution. The composites are useful for a variety of goods.

摘要： A method for producing continuous and discontinuous fiber metal matrix composites (CFMMC). The method uses aerosolization of finely divided metal powders in a controlled atmosphere which prevents explosions to coat the fibers and then the metal coated fibers are consolidated to form the CFMMC. The composites are useful as heat sinks for electrical components and in applications where a structural reinforced metal matrix composite is needed.

摘要： An apparatus and method for uniformly coating a fiber or tow of fibers (10) with a powder at relatively high speed to produce a prepreg. The apparatus uses an elongated chamber (401) in a container (400) for confining the fiber which is coated by an aerosol of powder dispensed from a powder dispensing apparatus (500) in counter-current mode. A fiber tensioning apparatus (300) for the fiber maintains the proper tensioning of the fibers spread by a speaker (201) below the fibers on roller bars (203) so that the uniformly spread fibers are fed to the chamber (401). A heater apparatus (600) fuses the powder to the fiber and then is taken up on a spool (700).

摘要： A system and method for uniformly coating one or more fibers (10) with particles of a material is described. The method uses a vibrator preferably an acoustic speaker (17b) in a housing (17c) to fluidize the particles (P.sub.1) in a chamber (17 or 30) to deposit them on spread fibers (10b). The fibers can be in the form of a tow of fibers. After the articles are coated on the fibers, the particles can be bonded to the fiber such as by using a heater (19). The resulting product has a uniform deposit of the particles and in the case of the tow of fibers can serve as a prepreg for laminate structures to be produced from the coated tow of fibers.
