Disclosed is a resin composite having improved tensile properties and a method of preparing the same. Particularly, the resin composite comprises a matrix resin and a reinforcement resin which are made of thermoplastic resin compositions.

Thermoplastic resin composite and method of preparing the same

A method of preparing a thermoplastic resin composite includes laminating a matrix resin layer and a reinforcing resin layer to prepare a resin laminate, and heat-bonding the resin laminate, and prior to the step of heat-bonding the resin laminate, fixing one or more selected from the group consisting of the reinforcing resin layer and the resin laminate using a stitch resin having a draw ratio of less than 10:1 and a melting point of 150&#xb0; C. or lower.

Thermoplastic resin composite and preparation method of thermoplastic resin composite

A method and an apparatus for manufacturing a linerless pressure vessel can be used for manufacturing a high pressure tank, by spinning of continuous fiber in a centrifugal direction.

Linerless pressure vessel by centrifugal forced weaving and method for manufacturing thereof

A non-cylinder type composite pressure vessel of a vehicle is provided. The vessel includes a nozzle boss that includes a neck part having a hollow portion and a flange part that extends outward from the neck part. Additionally, a liner is engaged with the nozzle boss, thereby forming in the inside thereof a fluid filling space. The liner is formed stepped along a rim of an outer side of a reinforced area formed at an end portion of the fluid filling space.

Non-cylinder type composite pressure vessel of vehicle

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.

Weaving method and apparatus for performing the same

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.

Apparatus for preventing deformation of plastic battery pack case for a vehicle

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.
