Title:
MANUFACTURING METHOD FOR AIR PERMEABLE METAL HOUSING STRUCTURE WHICH REDUCES FLUID RESISTANCE TO MOVING OBJECT AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/188556
Kind Code:
A1
Abstract:
A manufacturing method for an air permeable metal housing structure which reduces fluid resistance to a moving object, comprising: first, weaving metal fiber yarns to form a weave slab, then sintering same, and pressing the sintered fiber yarn slab by means of plastic processing, so as to compress the pore size of the sintered fiber slab, reducing porosity of the material, improving the mechanical property of the material, and maintaining communication between the pores of the material, so as to obtain an air permeable fiber metal plate; after that, using a plastic pressure processing method to make the air permeable metal plate have the shape and size of the housing of a moving object, so as to obtain an air permeable housing structure, such that one side of the multi-microporous air permeable metal plate material forms the outer surface of the housing of the moving object, and the other side thereof forms the inner surface of the housing of the moving object, forming an enclosed space. Pressure gas outputted from a gas source enters the enclosed space, and the gas penetrates through the multi-microporous air permeable metal housing material from one side of the multi-microporous air permeable metal housing to the other side of the multi-microporous air permeable metal housing, meanwhile the air permeable metal material can also maintain the structural shape of the moving object housing and satisfy the requirement of structural strength.
