Embodiment 1

[0027] Such as figure 1 As shown, it is a three-layer sandwich two-component composite panel, the total thickness is generally 20mm to 80mm. The total thickness of the composite board in this embodiment is 60mm. The skin is a thin plate such as aluminum plate, steel plate, glass steel plate or carbon fiber plate, and the thickness is generally 0.2mm to 10.0mm. In this embodiment, the first skin 11 is a 1.2mm aluminum plate, and the second skin 12 is a 1.0mm aluminum plate; the sandwich part includes three layers of sandwich materials, and the sandwich material is a PEI core material 25 with a thickness of 10 mm to 15 mm and a thickness of 24 combinations of PMI core materials of 27.8-37.8mm. Wherein, the PEI core material 25 is connected with the skin, and the PMI core material 24 is sandwiched inside two layers of PEI core materials 25 . The first skin 11 , the PEI core 25 , the PMI core 24 , the PEI core 25 and the second skin 12 are sequentially bonded by an adhesive to ...

Embodiment 2

[0031] Such as figure 2 As shown, it is a two-layer sandwich composite board with two components, the total thickness is generally 20mm to 80mm, and the total thickness of the composite board in this embodiment is 60mm. The skin is a thin plate such as aluminum plate, steel plate, glass steel plate or carbon fiber plate, and the thickness is generally 0.2mm to 10.0mm. In this embodiment, the first skin 11 is a 1.0mm aluminum plate, and the second skin 12 is a 1.0mm stainless steel; the sandwich part includes two layers of sandwich materials, and the sandwich material is a PES core material 22 with a thickness of 10 mm to 15 mm and a thickness of 43mm ~ 48mm PMI core material 24 combinations. The first skin 11 , the PES core 22 , the PMI core 24 and the second skin 12 are sequentially bonded by an adhesive to form a composite board.

[0032] The first skin 11 is made of lightweight aluminum plate, which can effectively reduce the weight of the composite plate and ensure suff...

Embodiment 3

[0035] Such as image 3As shown, it is a three-layer sandwich three-component composite board, and the total thickness is generally 20mm to 80mm. The total thickness of the composite board in this embodiment is 60mm. The skin is a thin plate such as aluminum plate, steel plate, glass steel plate or carbon fiber plate, with a thickness of 0.2mm to 10.0mm. In this embodiment, the first skin 11 is 2.0mm stainless steel, and the second skin 12 is 2.0mm stainless steel; the sandwich part includes three layers of sandwich materials, and there are three kinds of sandwich materials, and the sandwich materials are selected from PES core material 22, PVC The combination of the core material 23 and the PMI core material 24 is connected by buckling. The first skin 11 is bonded to the PES core material 22 with a thickness of 15 mm to 20 mm through an adhesive, and the second skin 12 is connected to the PMI core material 24 through an adhesive bond, wherein the thickness of the PMI core m...

Abstract

The invention relates to a composite board with a plurality of sandwich components for a transport facility, which comprises a first coating, a sandwich part and a second coating. The first coating, the sandwich part and the second coating are bonded in sequence; the connecting sandwich part consists of a plurality of sandwich materials; the connecting sandwich materials are compositions of any two or above kinds of functional polymer foam materials, such as polyethersulfone resin, polyetherimide, polymethacrylimide, polyvinyl chloride, polyurethane, polyethylene, polystyrene, acrylonitrile-styrene and the like. The composite board can adopt the sandwich composition with materials which have corresponding advantages and properties according to the particular requirements for the performance of the composite board in the actual application, so as to develop the advantages and properties of various materials. Moreover, the composite board with the sandwich components has an outstanding comprehensive performance. When the composite board is used for manufacturing transport facilities such as rail vehicles and the like, the invention can improve the comprehensive performances of the transport facilities and has a significant advantage in performance, a high performance-price ratio and a wide range of promotional value.

Description

technical field [0001] The invention relates to a multi-sandwich component composite board, in particular to a multi-sandwich component composite board applied to transportation tools such as rail vehicles in the traffic field. Background technique [0002] At present, in the field of transportation, composite panels are mostly used as structural parts. One of the advantages of composite panels is light weight and good rigidity. Not only does it have the performance advantages of the internal core material, but it also has a higher overall stiffness than the core material itself. The stiffness of the composite panel depends more on the thickness and thickness of the core material. The material properties of the skin. [0003] For the traffic field, in addition to the rigidity requirements, at least fire resistance and impact resistance are required. Therefore, the range of material selection is often limited to some core materials with excellent performance, such as polyeth...
