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:
A reinforced polymer composite includes a polymer matrix and a strengthening agent. The strengthening agent includes highly crystalline cellulose nanocrystals (CNC) and a stabilizing agent. The crystalline cellulose nanocrystals (CNC) have dimensions of about 3 to 5 nm in width and about 100 to 300 nm in length and a density of about 1.6 g/cm3 and the stabilizing agent may be one of Boehmite nanoclay (Boe) and Cetyltrimethylammonium Bromide (CTAB) or a combination of both.

Abstract:
A joined body includes: a first compact (1) that includes a fiber-reinforced resin (2) and a fiber exposure portion where a fiber (3) of the fiber-reinforced resin is exposed, the fiber exposure portion being formed on at least a part of a surface of the first compact (1); a second compact that is joined to the first compact (1) through a joint portion that is interposed between the fiber exposure portion of the first compact (1) and the second compact.
Abstract:
The present relates to a process for incorporating of wet natural fiber and starch into thermoplastics and the composite produced. The process for producing the composite comprises steps of: providing a wet natural fiber; providing a starch; providing a plasticizer; providing a thermoplastic; mixing the wet natural fiber, the starch and the plasticizer with water to produce a paste, and compounding the paste with the thermoplastic to produce the composite. The composite in a preferred embodiment comprises 50 weight % natural fiber/starch and a plasticizer; 50 weight % thermoplastic; a tensile modulus greater than 1450 MPa and a tensile strength greater than 41 MPa.
Abstract:
A cellulose-based natural fiber is added to an injection-molded plastic part, especially a fitting for the interior of a motor vehicle. In this manner, the strength of the part is increased and the fibers do not show on the surface.
Abstract:
The packaging has a tubular body (1), an apron, a head, an optional lid, and an added piece of material (8) on inner side of the apron. The apron has a rolled-up sheet and a longitudinal weld for assembling edges of ends of the apron together. The head is attached to the edge of one of the ends of the apron. The apron includes 30 percent of recycled material or material from renewable resources. A bottom portion is fixed to periphery of one of the ends of the apron.
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:
La présente invention a pour objet des panneaux (1) substantiellement rigides, dont la structure, exempte d'armature, comporte deux parois (2, 3) de faible épaisseur en un (des) matériau(x) composite(s) recyclable(s), solidarisées l'une à l'autre et entre lesquelles sont ménagés des vides (5); le(s)dit(s) matériau(x) composite(s) comportant une matrice thermoplastique renforcée par des fibres cellulosiques. Elle a également pour objet des pièces semi-structurelles d'habitacle ou de coffre de véhicules automobiles qui comportent dans leur structure de tels panneaux (1) et un procédé pour l'élaboration desdits panneaux (1).
