Embodiment Construction
[0017] In order to make the purpose and technical solution of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are some, not all, embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0018] Such as figure 1 As shown, a reinforced composite material plate structure is composed of a composite material surface layer 9, a metal structure frame 10 and a core material 11. The metal structure frame is in the shape of a cuboid as a whole, and the outside of the cuboid metal structure frame is covered with at least one layer of composite material. For the material surface layer, a plurality of reinforcing ...

The invention discloses an enhanced composite-material board structure. The enhanced composite-material board structure comprises composite-material surface layers, a metal structure frame and a core material. The metal structure frame is cuboid integrally, and at least one composite-material surface layer wraps the cuboid metal structure frame. A plurality of reinforcing ribs made from the same material of the metal structure frame are parallelly arranged in the metal structure frame along the thickness direction. The metal structure frame is filled with the core material made from foam. The enhanced composite-material board structure has the advantages that results of related mechanical property tests on tensile strength, tensile modulus, linear expansion coefficient and the like of the enhanced composite-material board show that heat insulation performance is good, tensile strength is high, thermal expansion coefficient is low, and the size of the enhanced composite-material board is stable.
Description
technical field [0001] The invention relates to the technical field of composite material plates, in particular to a reinforced composite material plate structure. Background technique [0002] The sandwich structure of composite materials consists of three parts. The outermost layer is the panel, which mainly bears the normal stress caused by bending deformation. It is made of high-strength and high-modulus materials, such as laminated carbon fiber or glass fiber cloth; the middle is the core material. Provide enough section moment of inertia for the sandwich structure, mainly bear the shear stress, commonly used honeycomb, foam, balsa and other materials. There is an adhesive layer between the panel and the core material, and the two are bonded together by resin, such as unsaturated polyester, vinyl resin, epoxy resin, phenolic resin, etc. are commonly used. Composite sandwich structure is a material and structural form with broad development prospects. The application fi...
