Description
Technical field
The invention belongs to materials processing technology field more particularly to a kind of metals and carbon fiber enhancement resin base composite material
The non-porous riveting set of laminate and its method.
Background technique
No riveting interconnection technique, which refers to, is squeezed connected sheet material using simple pyramid type punch-pin on stamping equipment
It is pressed into bottom to have among the cavity plate of endless groove, under the action of high pressure, the sheet material of punch-pin side is extruded to cavity plate side
Plate in, in further extrusion process, sheet material plasticity " flowing ", formed dovetail shaped inlay, so can be realized
Two kinds of materials are connected without riveting.
The principle of no riveting interconnection technique is the law of minimum resistance of metal, i.e., metal can be first to resistance minimum in deformation
Direction flowing.It is possible thereby to by the shape, structure of design mold so that metal is deformed according to our wish.But carbon
Fiber-reinforced resin matrix compound material plasticity after solidified forming is poor, cannot deform as metal.And due to plasticity
Difference, the carbon fiber enhancement resin base composite material being cured have biggish rebound after punching press, are unfavorable for forming dovetail shaped
It inlays, the contact strength for meeting application requirement cannot be generated.Therefore, directly metal/carbon fiber is increased using no riveting interconnection technique
It is unpractical that strong polymer matrix composites laminate, which is attached,.
Summary of the invention
In view of the problems of the existing technology, the present invention provides a kind of metal and carbon fiber enhancement resin base composite material layer
