Description

A composite material container

technical field

The invention relates to a composite material container, which belongs to the field of transportation.

Background technique

Container refers to a large-scale loading container with certain strength, rigidity and specifications specially used for turnover. Using containers to transship goods can be directly loaded in the consignor's warehouse and unloaded in the consignee's warehouse. When changing vehicles or ships midway, there is no need to take out the goods from the box for repacking. Traditional containers are generally made of metal materials, wood, etc. Due to the limitation of manufacturing materials, their durability and weight have been greatly affected.

Wooden containers are cheap, but they are prone to moisture deterioration and damage. The advantages of steel containers are high strength, firm structure, good weldability and watertightness, low price, easy repair, and not easy to damage. The main disadvantages are heavy weight and poor corrosion resistance. The advantages of aluminum containers are light weight, no rust, beautiful appearance, good elasticity, and not easy to deform. The main disadvantages are high cost and easy damage when collided. The advantages of stainless steel containers are high strength, no rust, and good corrosion resistance. The disadvantage is that the investment is large. The advantages of FRP containers are good heat insulation, anti-corrosion and chemical resistance, high strength and good mechanical properties. The main disadvantage is that the weight is large and the cost is high.

Contents of the invention

The object of the present invention is to provide a novel composite material container aiming at the shortcomings of the above-mentioned existing containers.

The object of the present invention can be achieved through the following measures:

A container made of composite materials, including bottom panels, side panels, top panels, end panels, and doors, characterized in that all or part of the above components are made of composite material sandwich panels, and the composite material sandwich panels are composed of panels 1 and core materials 2 . The panel 1 is a fiber material, the core material 2 is a lightweight material, the panel 1 is arranged on the upper and lower surfaces of the core material 2, and the panel 1 and the core material 2 are formed by curing resin.

The core material 2 is Balsa wood, paulownia wood, Chinese fir, oak, plywood, polyurethane foam, polyvinyl chloride foam or carbon foam.

The panel 1 is uniaxial, biaxial or multiaxial carbon fiber, glass fiber, aramid fiber or hybrid fiber cloth layer.

The resin is unsaturated polyester, vinyl resin, epoxy resin or phenolic resin.

The present invention has the following advantages:

The main component of a composite material container is a composite material sandwich panel. The composite material sandwich panel gives full play to the high-strength properties of fiber materials, which can effectively reduce the number of various beams. At the same time, the composite material sandwich panel itself is a lightweight material, so it can effectively reduce the The overall weight of the container, which is especially beneficial for air transport. At the same time, the surface of the composite sandwich panel is a panel formed by curing fibers and resin, which has good corrosion resistance and good durability. The core material of the composite sandwich panel is a poor conductor of heat, and after using it to make a container, the container has better heat insulation performance. The application fields of the composite material container are wide, and the development prospect is broad.

According to different needs, some of them can be made of composite sandwich panels or all of them can be made of composite sandwich panels.

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

Example 1

In the composite material container involved in the present invention, the panel of the composite material sandwich panel is made of glass fiber cloth and vinyl resin cured, the core material is polyurethane foam, and the composite material sandwich panel is manufactured by one-time integral molding technology. According to the needs, the composite sandwich panel is processed into the shape required by the bottom panel, side panel, bottom panel, end panel, and door. The boards are glued together, and a small amount of metal parts are used to connect each board into the required container shape. The composite material container thus formed has the function of heat preservation.

Example 2

In the composite material container involved in the present invention, the panel of the composite material sandwich board is made of glass fiber cloth and vinyl resin cured, and the core material is paulownia wood profile board. Lay glass fiber cloth on the upper and lower surfaces of Paulownia wood, and inject resin. After the resin is completely cured, a composite material board with Paulownia wood as the sandwich material is formed. Composite sandwich panels are processed to the required size, then bonded with strong adhesives, and supplemented with a small amount of metal parts, thus forming a low-cost composite container.

Example 3

In the composite material container involved in the present invention, the bottom plate 3 is made of high-strength composite material sandwich plate, and the side plate 4, top plate 5, end plate 6 and door 7 are all made of aluminum alloy. The face plate 1 of the composite sandwich panel used for the bottom plate is cured with mixed fibers and epoxy resin, and its core material 2 is Balsa balsa wood.

The manufacturing method of the above-mentioned composite material container can be briefly described as follows:

(1) Grooves are made on the surface of polyurethane foam and balsa wood (comprising: Balsa wood, paulownia wood, etc.) Fiber cloth (including: uniaxial, biaxial or multiaxial carbon fiber, glass fiber, aramid fiber and hybrid fiber cloth, etc.) is laid on the upper and lower surfaces of the core material 2, and placed into the required shape ;

(2) Seal the test piece that has been placed, and pour the resin into the vacuum bag or mold through the vacuum bag forming process, vacuum introduction forming process or RTM (resin transfer molding) forming process;

(3) After the resin is cured and formed, it is taken out to form a composite material sandwich panel, and the composite material sandwich panel is cut into a desired shape;

(4) Bond the cut composite material sandwich panels with high-strength resin glue, and connect each panel with a small amount of metal parts, which constitutes the composite material container described in this article.
