Abstract:
A spring member of a suspension for a vehicle may include a spring provided to be supported between a lower seat disposed in the suspension and a car body to provide an elastic force, wherein an inner part of the spring is formed in a shape of a hollow corrugated tube.
Abstract:
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.
Abstract:
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° C. or lower.
Abstract:
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.
Abstract:
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.

Abstract:
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.
