Embodiment 1

[0043] Taking a flat-bed semi-trailer with a length of 13.6 meters, a width of 2.6 meters, and a load of 40 tons as a model, the existing steel flat-bed semi-trailer weighs about 4 tons.

[0044] The fiber material in the fiber-reinforced composite board adopts large tow carbon fiber (≥48K), and the resin is epoxy resin.

[0045] (1) VARTM process is used to form the shell 1. The specific preparation method is: set a metal mold with a heating device, spray HD-918-V release agent (produced by Shanghai Dongheng Chemical Co., Ltd.), respectively, at 0°, + 45°, -45°, 90° angles, circularly lay large tow carbon fiber unidirectional fabric, lay about 8-10mm thick, wrap the whole mold with a vacuum bag, inlay a sealing strip on the edge of the mold, and evacuate one end of the mold, 0.05~ Hold the pressure at 0.07MPa for 3-5 minutes, then introduce epoxy resin glue from the other end, and heat and cure. The curing conditions are: temperature, 170°C; time, 2h. After the curing was co...

Embodiment 2

[0051] Taking a flat-bed semi-trailer with a length of 13.6 meters, a width of 2.6 meters, and a load of 40 tons as a model, the existing steel flat-bed semi-trailer weighs about 4 tons.

[0052] The fiber material in the fiber-reinforced composite board adopts large tow carbon fiber (≥48K) and glass fiber, and the resin is unsaturated polyester.

[0053] (1) The shell 1 is formed by vacuum bag technology, a metal mold with a heating device is installed, and HD-918-V release agent is sprayed, and the angles of 0°, +30°, -30°, and 90° are alternated Circularly lay large tow carbon fiber unidirectional prepreg fabric and glass fiber unidirectional prepreg fabric, laying about 12-15mm thick, wrap the whole mold with a vacuum bag, insert a sealing strip on the edge of the mold, vacuumize, and keep it under 0.05-0.09MPa Press for 3-5 minutes, heat and cure. The curing conditions are: temperature 110°C; time 1.5h. After the curing is completed, the temperature is lowered to room te...

Embodiment 3

[0060] Taking a flat-bed semi-trailer with a length of 13.6 meters, a width of 2.6 meters, and a load of 40 tons as a model, the existing steel flat-bed semi-trailer weighs about 4 tons.

[0061] The fiber material in the fiber reinforced composite board is glass fiber, and the resin is vinyl resin.

[0062] (1) The shell 1 is molded by the RTM process, a metal mold with a heating device is set, the HD-918-V release agent is sprayed, and multi-layer glass fiber twill fabric is laid with a thickness of about 15-20mm, and the edge of the female mold is inlaid Sealing strip, seal the female and male molds, vacuumize the cavity (0.05-0.09MPa), hold the pressure under negative pressure for 3-5 minutes, and then introduce vinyl resin glue from the other end, curing conditions is: temperature, 130°C; time, 1h. After the curing is completed, the temperature is lowered to room temperature, the mold is opened and taken out to obtain the shell 1, and the height of the shell is 560 mm. ...

Abstract

The invention relates to a flatbed semitrailer body, comprising a bearing shell, a bottom plate and a support beam, wherein the shell is bonded with the lower surface of the bottom plate and constitutes a box-shaped structure together with the bottom plate, and the support beam is located inside the box-shaped structure and is connected with the shell and the bottom plate. The invention further relates to a manufacture method of the flatbed semitrailer body. According to the invention, the semitrailer body is effectively reduced in weight in terms of both structure and material, because the semitrailer body is manufactured in an integral molding manner, all parts are good in connection performance, the number of maintenance times can be reduced obviously, the service life can be prolonged obviously, and the semitrailer body is made of macromolecular composite materials and is capable of effectively tolerating corrosion and very good in resistance to the effects of acid, alkali, salt, most organic matters and microorganisms. For the manufacture method of the semitrailer body, a traditional molding process can be adopted, so that the manufacture method is simple and convenient in process conditions and suitable for large-scale industrial application.

Description

technical field [0001] The invention relates to a flat semi-trailer body and a manufacturing method thereof, in particular to a lightweight flat semi-trailer body and a manufacturing method thereof. Background technique [0002] Existing flatbed semi-trailers are generally made of steel and are composed of base plates, vehicle frames, suspensions and wheel assemblies. Among them, the frame is a frame structure composed of two large I-shaped steel longitudinal beams that are larger than the total length of the bottom plate and several cross beams, providing the load-bearing capacity and rigidity required by the whole vehicle, such as figure 1 shown. Its disadvantage is that the weight of the vehicle frame itself is very large, and the consumption of steel materials will account for 25% of the weight of the vehicle. [0003] Fiber-reinforced composites are a new type of material that has developed rapidly in recent years. It is usually composed of matrix resin and fiber rein...
