Abstract:
An elongate composite structural member and method of making the same which is particularly useful for forming the handle of hand-held striking and prying tools or implements. The elongate structure member comprises a foamed in place molded resin composition core and outer skin layer which is reinforced with intermediate layer of structurally strong, unidirectional oriented fibers. The expanded foam resin, intermediate fiber layer and the expanded foam resin outer skin are bound together by the cured foamed resin composition formed during the molding process to form a strong, integral composite structure.
Abstract:
Fibrous materials, compositions that include fibrous materials, and uses of the fibrous materials and compositions are disclosed. For example, the fibrous materials can be operated on by a microorganism to produce ethanol or a by-product, such as a protein or lignin. In particular, a method of densifying a fibrous composition is disclosed, the method comprising: shearing a fiber source to provide a fibrous material; combining the fibrous material with a microorganism and/or enzyme to provide a fibrous material composition; encapsulating the composition in a substantially gas impermeable material; and removing entrapped gas from the encapsulated composition to densify the composition.
Abstract:
The invention relates to an acoustic product composed of composite material, such as a musical musical instrument, a part thereof, an acoustic equipment or like, which is manufactured from raw material comprising at least cellulose based substance and plastic based substance by means of a thermoplastic process, such as by pressing, compression molding, injection molding, extrusion, blow molding by heat, rotational molding and/or the like. The acoustic product has a material composition consisting of fiber substance (1) based on surface modified cellulose and plastic based substance (2), wherein the product has an essentially wood-like, but isotropic sound.
Abstract:
The present invention relates to production method of a composite material wherein the composite material is tensioned and cured to produce a composite material with a single cord or cord fabric reinforced with another component, comprising the steps of adhering at least two layers of compound material, attaching the adhered compound materials inside a hollow frame, placing said frame into a pre-tensioning device, wrapping the cords around the frame with the desired pre-tension, removing the frame together with the compound material and the cords from the pre-tensioning device, placing at least one layer of compound material on the curing tray, placing the coated frame removed from the pre-tensioning device onto the compound material layers, placing at least one more layer of compound material on the coated frame, closing the lid over the curing tray, curing the material and cutting the composite material into strips.
Abstract:
A composition includes: a) polystyrene, the polystyrene including polybutadiene; b) vegetal fibers having a length lower than 50 μm; and c) at least one compatibility agent including a polybutadiene maleic anhydride copolymer, the copolymer including at least 17% by weight of the copolymer of maleic anhydride. The composition is used for manufacturing a plastic composition. The plastic composition obtained by heating the composition, a sheet obtained by extruding the plastic composition, and a container obtained by thermoforming the sheet are also described.
Abstract:
A flexible hose having a non-fluorinated rubber inner tube, a non-fluorinated rubber outer cover, an intermediate barrier layer consisting essentially of ethylene-vinyl alcohol copolymer (EVOH) having an ethylene content less than 30 mole %, and preferably a textile reinforcement between said barrier layer and said outer cover. A non-fluorinated rubber tie layer may be included between the barrier and the reinforcement. Permeability to ethanol- and methanol-containing fuels is very low.
Abstract:
The present invention is directed to a method of making a flexible hose (10), comprising the steps of extruding a first poly(vinyl chloride) compound to form a tube (1), the tube having an inner cylindrical cavity coextensive with the tube; a) applying a textile reinforcement (5) over the tube; b) extruding a second poly(vinyl chloride) compound over the textile reinforcement to form a cover layer (6), said tube, reinforcement and cover layer defining a hose composite; c) inserting a rigid mandrel into the inner cylindrical cavity; d) wrapping a fabric wrap around the outside of the cover of the hose composite; and e) processing the wrapped hose composite at a temperature in a range of 130° to 160°C and a pressure of 30 to 70 psig for a time ranging from 5 to 40 minutes.
Abstract:
In the manufacture of a fibrous rod-like article for use, particularly as cigarette filters, a tow 2 of cellulose ester fibres is drawn from a bale 1, formed into the required shape and then impregnated with a carboxylic acid ester of a polyol. The impregnated tow 2 is then passed through a microwave irradiating device 10 and simultaneously with, or prior to, passage through the device (10) water is supplied to the tow. The water enhances the absorption of microwave energy by the tow, causing the carboxylic acid ester of the polyol rapidly to disperse and permeate the acetate fibre and hence rapidly complete the stabilization and solidification of the fibrous rod.
