Abstract
The invention relates to a composite material assembly cushion with the shape being consistent to an assembly clearance. Epoxy resin cured at normal temperature is mainly used as a substrate, and reinforcement made of glass fiber or carbon fiber is arranged in the substrate. A manufacturing method comprises the following steps of: (1) impregnating the reinforcement made of the glass fiber or the carbon fiber and the epoxy resin into prereg; (2) filling the prereg into the assembly clearance, and adopting an isolating membrane for isolating; (3) assembling two assembly parts, connecting by a code pulling device, applying positive pressure on the assembly clearance, extruding redundant epoxy resin, and carrying out curing at normal temperature; and (4) after curing the prereg, disassembling the code pulling device, finishing the surface of the cured prereg, and finally carrying out part assembling. The composite material assembly cushion can be filled in the assembly clearance formed in an assembly process, so that zero-clearance assembly is realized.
Description
Technical field
The present invention relates to a kind of composite material assembling cushion and preparation method thereof, belong to composite material mounting technology field.
Background technique
The carbon fiber composite part has advantages such as lightweight, Gao Mo, high-strength and designability because of it, begin to find just to have catered to from the seventies in last century to have obtained the demand in sophisticated technology fields such as Aeronautics and Astronautics and national defence to use widely.On the other hand, because the carbon fiber composite part exists tolerance of size and toughness lower, be assembled in the builtup member process at it and can produce the fit up gap.If directly adopt the fastening by force applyings of standard piece such as high locked bolts or rivet, can cause serious layering in the part area.In recent years, some accidents relevant with assembly technology have caused the very big concern of industry.To this type problem, adopt pad to fill the gap usually, as shown in Figure 1, conventional pads generally has glass epoxy pad or metallic shim etc.But,,, can not eliminate the hidden danger that assembly process causes damage fully if directly the use conventional pads can be filled unreal or new gap occurred because the fit up gap is not equally spaced.
Summary of the invention
The technical problem that the present invention will solve provides a kind of composite material assembling cushion and preparation method thereof, and fill the fit up gap that this composite material assembling cushion can produce in assembly process, thereby realize the zero clearance assembling.
For overcoming the above problems; Concrete technological scheme of the present invention is following: a kind of composite material assembling cushion; The shape of this cushion is consistent with the assembling slit, and it is a matrix with the epoxy resin of normal temperature cure mainly, is provided with the enhancing body of glass fibre or graphite fiber in the inside of matrix.
The making method of composite material assembling cushion, by following steps:
1) the enhancing body with glass fibre or graphite fiber becomes prepreg with the epoxy resin infuse;
2) prepreg is filled in the fit up gap, and adopts isolating film to separate;
3) then with after the assembling of two Assembly parts, with drawing yard device to connect, the place applies positive pressure to the fit up gap, extrudes unnecessary epoxy resin, and carries out normal temperature cure;
4) treat that prefabricated material solidifies after, remove and draw a yard device, the part equipment is carried out on the surface that prefabricated material has been solidified in finishing at last.
Adopt the composite material cushion film of above-mentioned steps preparation, the fine filling of ability fit up gap has guaranteed the applying fully between part and pad, has realized the assembling of " zero " gap, has eliminated the potential possibility that is caused part injury by assembling.

Fig. 1 fills schematic representation for conventional pads.
Fig. 2 fills schematic representation for composite material assembling cushion.
Wherein Fig. 1, matrix; 2, strengthen body; 3, isolating film; 4, part I; 5, part II; 6, packless gap; 7, conventional pads.
Embodiment
As shown in Figure 2, a kind of composite material assembling cushion, the shape of this cushion is consistent with the assembling slit, and it is a matrix 1 with the epoxy resin of normal temperature cure mainly, is provided with the enhancing body 2 of glass fibre or graphite fiber in the inside of matrix 1.
The making method of composite material assembling cushion, by following steps:
1) the enhancing body 2 with glass fibre or graphite fiber becomes prepreg with the epoxy resin infuse;
2) prepreg is filled in the fit up gap, and adopts isolating film to separate;
3) then with after the assembling of two Assembly parts, with drawing yard device to connect, the place applies positive pressure to the fit up gap, extrudes unnecessary epoxy resin, and carries out normal temperature cure;
4) treat that prefabricated material solidifies after, remove and draw a yard device, the part equipment is carried out on the surface that prefabricated material has been solidified in finishing at last.
Claims (2)
1. a composite material assembles cushion, it is characterized in that: the shape of this cushion is consistent with the assembling slit, and it is matrix (1) with the epoxy resin of normal temperature cure mainly, is provided with the enhancing body (2) of glass fibre or graphite fiber in the inside of matrix (1).
2. the making method of composite material assembling cushion as claimed in claim 1 is characterized in that by following steps:
