20120103714 | BATTERY PACK HOUSING ASSEMBLY FOR ELECTRIC VEHICLE USING PLASTIC COMPOSITE MATERIAL - The present invention provides a battery pack housing assembly for an electric vehicle, which is formed of a lightweight composite material to reduce the weight and configured to have a dual laminated structure with a closed cross-sectional area formed by composite molding to absorb impact energy. For this purpose, the present invention provides battery pack housing assembly for an electric vehicle using a plastic composite material, the battery pack housing assembly having an upper cover mounted at the bottom of a vehicle body, a lower housing, and a battery pack received and mounted in the lower housing, wherein the lower housing has a dual laminated structure with a closed cross-sectional area formed by bonding an upper plate and a lower plate, each composed of a fiber reinforced plastic composite material, to absorb impact energy, thus increasing structural stiffness. | 05-03-2012 |
20130059187 | APPARATUS FOR PREVENTING DEFORMATION OF PLASTIC BATTERY PACK CASE FOR A VEHICLE - Disclosed is an apparatus and method for preventing deformation of a plastic battery pack case for a vehicle, in which the side of the battery pack case is subjected to reverse deformation to absorb the deformation occurring after compression molding and to ensure the dimensions of a mounting portion of various components including battery packs, thereby ensuring an internal space of the battery pack case. To this end, the present invention provides an apparatus for preventing deformation of a plastic battery pack case for a vehicle, the apparatus including: a base having a case insertion space; a fixing portion for fixing a battery pack case inserted into the case insertion space; and a deformation producing portion inserted into the battery pack case and preventing the case from being deformed by pressing the inside of the case to be reversely deformed in the lateral direction. | 03-07-2013 |
20130065469 | LARGE TOW CARBON FIBER COMPOSITE WITH IMPROVED FLEXURAL PROPERTY AND SURFACE PROPERTY - Disclosed is a carbon fiber composite comprising 30 to 80 wt % of a carbon fiber textile wherein a carbon fiber tow size is 24K to 100K; 0.1 to 20 wt % of a carbon non-woven fabric whose weight per unit area is 10˜500 g/m | 03-14-2013 |
20130125740 | PLASTIC COMPOSITE SPRING FOR VEHICLE SUSPENSION AND APPARATUS AND METHOD FOR MANUFACTURING THE SAME - Disclosed is a corrugated plastic composite spring for a vehicle suspension and an apparatus and method for manufacturing the same. The apparatus includes a corrugated extrusion part, a braiding part, and a pultrusion part. The corrugated extrusion part forms a preform having a hollow corrugated structure. The braiding part weaves a three-dimensional woven fabric on the preform. The pultrusion part impregnates the three-dimensional woven fabric with thermosetting resin. | 05-23-2013 |
20140182447 | METHOD OF MANUFACTURING CORRUGATED PREFORM USING BRAIDING PROCESS - A method of manufacturing a corrugated preform that allows a fiber volume fraction and an orientation angle to be substantially the same at a concave portion and at a convex portion when the corrugated preform is manufactured based on a braiding process. The method includes braiding a compound material corresponding to an outer diameter of a cylindrical cylinder shape, braiding the compound material by connecting a plurality of separate compound materials to one side of the braided compound material, and braiding the compound material to one side of the separate compound material corresponding to the outer diameter of the cylindrical cylinder shape. | 07-03-2014 |
20150174830 | WEAVING METHOD AND APPARATUS FOR PERFORMING THE SAME - Disclosed are a method of spinning a continuous fiber without a mandrel to manufacture a hollow cylinder part and an apparatus for manufacturing the hollow cylinder part using the same method. | 06-25-2015 |
