Composite board for ocean platform living quarter enclosure wall and preparation method of composite board

Abstract

The invention discloses a composite board for an ocean platform living quarter enclosure wall and a preparation method of the composite board, and belongs to the technical field of ocean engineering.The problems that a traditional enclosure wall for a platform is of a steel plate and square steel beam reinforced structure, the overall structure weight is large, and the heat insulation and sound insulation performance is poor are solved. Through a short fiber toughening layer, the problem that a composite material is prone to interlayer cracking in ocean engineering is solved. Damping, shock absorption and sound insulation properties of the composite material are improved through a carbon fiber elastomer composite layer, and the strength is improved and the overall structural weight is reduced by compounding the composite material with metal foam. Compared with traditional metal materials such as steel and aluminum alloy, the composite material has a much higher strength ratio, the weight of the platform can be greatly reduced and the platform is convenient to install and maintain when the composite material is applied to the marine drilling platform, the effective load and the operation range can be increased through the lighter structure, and great contribution is made to light weight of the drilling platform.

Description

technical field [0001] The invention relates to a composite board for the surrounding wall of the living area of ​​an ocean platform and a preparation method thereof, belonging to the technical field of ocean engineering. Background technique [0002] The semi-submersible platform living building needs to meet the work and living needs of a large number of staff on the platform, and is usually large in scale; and the conventional living building is located above the main deck and is rigidly connected to the main deck. Bear the total deformation load of the platform; at the same time, because the semi-submersible platform has better motion performance but less load capacity, it requires higher structural weight of the platform. Therefore, the surrounding wall applied on the semi-submersible platform should have the characteristics of high strength and light weight. The existing platform uses the traditional wall as the inner wall and the outer wall, both of which are reinfor...

AI Technical Summary

Problems solved by technology

The existing platform uses the traditional wall as the inner wall and the outer wall, both of which are reinforced by steel plates and square steel beams. The overall structure is heavy, and the traditional wall needs to be sandwiched between the inner and outer walls in order to solve the heat insulation and sound insulation performance. Insulation layers such as glass rock wool further increase the weight of the overall structure. Although the existing sandwich structure of carbon fiber composite materials can solve the above-mentioned heat and sound insulation problems, its temperature resistance and structural strength cannot directly replace the inner and outer walls, and carbon fiber composite materials in During application, interlayer cracking is prone to occur
