Problems solved by technology

[0003] (1) The high density causes the weight of the overall car door to be heavy, which will cause the overall weight of the car to be too high, which is not conducive to energy saving
[0004] (2) At the same time, the metal material is easy to deform, which will cause deformation when subjected to external force, which will cause poor sealing around the door and cause coal leakage during transportation, resulting in a lot of waste
[0005] (3) The surface of the metal material is highly polar, and it is easy to freeze on the surface in winter and has good bonding strength, making it difficult to open the door
[0006] (4) It is easy to corrode and requires regular maintenance on the door

Embodiment 1

[0026] Lay 20 layers of unidirectional continuous fiber reinforced polypropylene prepreg tape (thickness: 0.33mm, produced by Liaoning Jieshijie New Material Co., Ltd.) according to 0 / 90, and heat the laid material in an infrared oven for about 4 minutes The resin is melted, and then the melted composite material is quickly transferred to the mold, pressurized and maintained for about 3 minutes to cool, the mold is opened, taken out, and trimmed to obtain an all-thermoplastic composite door. Then connect and fix the pressed composite material car door with the handle to obtain a complete car door.

Embodiment 2

[0028] Lay 15 layers of hybrid fiber cloth woven by OCV's Twintex (polypropylene fiber and glass fiber mixed yarn), put the laid material in an infrared oven and heat it for about 3 minutes to melt the resin, and then quickly transfer the molten composite material Put it into the mold, pressurize and hold the pressure to cool for about 3 minutes, open the mold, take it out, trim the edge, and get a full thermoplastic composite door. Then connect and fix the pressed composite material car door with the handle to obtain a complete car door.

Embodiment 3

[0030] Put the 6mm thick 0 / 90° composite TPAC sheet (produced by Liaoning Jieshijie New Material Co., Ltd.), put the paved material in an infrared oven and heat it for about 5 minutes to melt the resin, and then quickly melt the molten composite material Transfer to the mold, pressurize and hold the pressure to cool for about 3 minutes, open the mold, take it out, trim the edge, and get the full thermoplastic composite door. Then connect and fix the pressed composite material car door with the handle to obtain a complete car door.

Abstract

The invention relates to a manufacturing method of a thermoplastic composite vehicle door, comprising the following steps of: piling up a composite material until its thickness reaches 5-8mm, heating the material in a baking oven to fuse matrix resin in the composite material, transferring the fused composite material into a vehicle door die, controlling the temperature of the die within 40-120 DEG C for die locking, maintaining the die pressure at 2-40MPa, maintaining the pressure for 1-5 minutes, performing cooling setting, taking out and trimming to obtain a thermoplastic composite vehicle door main body, and fixedly connecting the vehicle door main body with a handle to obtain the thermoplastic composite vehicle door. In comparison with the prior art, the vehicle door obtained in the invention is light in weight, has more excellent deformation resistance and better endurance, will not deform permanently, has good weatherability and corrosion resistance, and is convenient to maintain.

Description

technical field [0001] The invention relates to a manufacturing method of a car door, in particular to a manufacturing method of a thermoplastic composite material car door. Background technique [0002] At present, the transportation of coal is mainly carried by trucks. For the convenience of coal unloading, multiple doors are installed on each carriage. Currently, the doors of such trains are mainly metal. Metal materials have their advantages, such as high strength and rigidity. However, due to its characteristics, there are the following problems: [0003] (1) The high density causes the weight of the whole car door to be heavy, which will cause the excessive weight of the whole car compartment, which is not conducive to energy saving. [0004] (2) metal material deforms easily simultaneously, causes deformation when being subjected to external force, and this can cause the bad sealing around the car door to cause the leakage of coal in the transportation process, cau...
