Abstract

The invention discloses an integrally formed composite door leaf and a manufacturing method of the composite door leaf. The composite door leaf comprises a composite door plate, a front press strip, a back press strip, a front sealing rubber strip, a back sealing rubber strip, a door carrying frame, a lower slide block assembly and tempered glass, wherein the tempered glass is arranged on the upper half part of the composite door plate and forms an observation region; the door carrying frame is fixed above the composite door plate through screw bolts; the lower slide block assembly is fixed under the composite door plate through screw bolts; the front press strip and the back press strip are arranged at the two side edges of the composite door plate; the front sealing rubber strip and the back sealing rubber strip are arranged on the press strips of the symmetrical sides; and the sealing of the composite door leaf is realized. The composite door plate comprises an upper fiber reinforced composite panel, a filling core material layer, a reinforcing sectional material, an embedding element and a lower fiber reinforced composite panel which are in sequential distribution from top to bottom. Compared with a conventional aluminum alloy door leaf, the composite door leaf achieves the goals of simplifying production flow processes, saving the energy and reducing the cost, improves the taking comfort of a rail vehicle, and has good application prospects.

Description

technical field [0001] The invention relates to an integrally formed composite door leaf and a manufacturing method thereof, belonging to the technical field of rail vehicle transportation. Background technique [0002] At present, the traditional aluminum alloy door leaf used on rail vehicles has an internal filling material of aluminum honeycomb, a skeleton of an aluminum profile, and a skin of an aluminum plate. The production process of aluminum alloy door leaves includes profile blanking, profile machining, cleaning, welding, grinding, punching and shearing of aluminum skin, bending, cleaning, cloth glue, bonding and curing, glue removal, painting and other processing processes, There are many processes, the cost of quality control is high, and the aluminum alloy door leaves produced have disadvantages such as poor heat insulation performance, poor sound insulation performance, high density, and poor corrosion resistance. Contents of the invention [0003] The purpos...
