The present invention provides a fiber-reinforced-resin composite molded article including: a rigid layer that is formed of a fiber-reinforced-resin material for a rigid layer; a shaping layer that is formed, at least on one side of the rigid layer, of a shaping-layer compound composed of a thermosetting resin and fibers that are shorter than fibers contained in the fiber-reinforced-resin material for a rigid layer; and a cured resin being formed of a liquid-state resin that is deposited on the surface of the shaping layer. The fiber-reinforced-resin composite molded article has a structure in which the fiber-reinforced-resin material for a rigid layer, the shaping-layer compound, and the liquid-state resin are cured under heat and pressure in a layered state.
Process for producing composite material parts by impregnating a specific preform
A method for producing a composite material. The method includes the steps of producing an initial dry preform, formed from unidirectional continuous dry fibers, applying non-woven filaments to a first main face of the dry preform, and needling the filaments with a needling device. The needling device includes a plurality of needles, each provided with at least one notch, so that filaments are driven by the needles and arranged in a direction substantially perpendicular to the continuous fibers of the dry perform. The method includes the further step of impregnating the dry preform with an impregnation polymer, the impregnation polymer constituting the matrix of the composite material part.
Composite building materials and methods of manufacture
An example composite building material includes one or more layers of polymeric fibers, binding agent, and optional fillers, and at least one surface layer of resin-impregnated paper disposed above and/or below the one or more layers. The one or more layers can include a core layer with longer polymeric fibers and top and bottom layers with shorter polymeric fibers. A method of manufacturing the composite building material includes forming the one or more layers, applying the at least one surface layer above and/or below the one or more layers, and heating and pressing the combined layers.
PROCESS FOR MANUFACTURING A MOTOR VEHICLE PART
A process for manufacturing a motor vehicle part, wherein the part is produced by molding a filled thermoplastic material, the part thus molded is subsequently reinforced by positioning locally and at the surface of the part at least one reinforcing element including strips of unidirectional continuous fibers, the strips being deposited non-continuously on the part in at least one stress concentration zone.
Acoustically Effective and Dimensionally Stable Molded Part
Acoustically effective molded part which is dimensionally stable after pressure and heat treatment, consisting of a mechanically solidified staple fiber nonwoven fabric formed from fibers, namely from matrix fibers, bicomponent hotmelt adhesive fibers and thermoplastic adhesive fibers, as well as comprising an outer layer and a middle layer, wherein flattenings formed by adhesive fibers are located on the outer layers of the molded part, there are no flattenings in the middle layer of the molded part, the outer layer has a flattening degree according to the test method mentioned in the description of 25% to 75%, the outer layer has a thickness of 15 μm to 40 μm and the molded part has a specific flow resistance in the range from 1000 to 3000 Pas/m.
A METHOD FOR MANUFACTURING AN OVERHEAD STORAGE COMPARTMENT FOR AN AIRCRAFT CABIN
A method for manufacturing an overhead storage compartment for an aircraft cabin, including providing a shell part extending between a first end and a second end, wherein the shell part has a first edge at the first end and a second edge at the second end. A first end wall and a second end wall are provided. The shell part and the first and second end walls are assembled, wherein the first edge is attached to the first end wall and the second edge is attached to the second end wall, such that the shell part, the first end wall and the second end wall together surround an interior space. An object, to provide a simple and fast method for manufacturing an overhead storage compartment, wherein possibly little handwork is required, is achieved in that the first end wall and/or the second end wall include an undirected long fiber reinforced plastic material.
Method and apparatus for manufacturing a body made of composite material provided with an inner cavity with an outward opening
The present invention relates to a method of manufacturing a body made of composite material such as a shell of a helmet. Said body constitutes a multilayer structure where each layer is formed by superposed strata comprising portions of fabrics preimpregnated with thermoplastic resin in which at least some of said layers are formed by woven or non-woven LFRTP-type preimpregnated fabrics. The outer layer is formed by strata of portions of “veil” type or “felt” type fabrics, with non-woven and non-oriented fibers of lengths comprised between 5 and 20 mm. In the method, the multilayer structure arranged in a mold is subjected to the action exerted by a bag that is inflated due to pressure occupying the cavity of the mold.
MOLDABLE UNCURED NONWOVEN COMPOSITE AND MOLDED CURED COMPOSITE
A process for forming a moldable, uncured nonwoven composite containing forming a outermost nonwoven layer, forming a structural nonwoven layer, needling the structural nonwoven layer and the outermost nonwoven layer together from both the outer surface of the outermost nonwoven layer and the second surface of the structural nonwoven layer, applying an uncured, water-based thermosetting resin having a cure temperature of at least about 160° C. to the second surface of the structural nonwoven layer, and at least partially drying the uncured, wet nonwoven composite. Heat and pressure may be applied to form the moldable, uncured composite. A moldable, uncured nonwoven composite and a molded, cured nonwoven composite are also disclosed.
COMPOSITE ARTICLES COMPRISING NON-LINEAR ELONGATED NANOSTRUCTURES AND ASSOCIATED METHODS
