Fig. 1 is a flow chart, and first preferred embodiment of the manufacturing approach of the composite material work piece that buries metalwork in the present invention is described;
Fig. 2 is a sketch map, aid illustration Fig. 1;
Fig. 3 is a sketch map, and second preferred embodiment of the manufacturing approach of the composite material work piece that buries metalwork in the present invention is described.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.Before the present invention is described in detail, be noted that in following description similarly assembly is to represent with identical numbering.
Consult Fig. 1, first preferred embodiment for the manufacturing approach of the composite material work piece that buries metalwork in the present invention comprises one first heat-press step 21, and one second heat-press step 22.
Consult Fig. 1,2, this first heat-press step 21 is with the multilayer first preimpregnation nonwoven fabric layer 3 alignment and congruences, and synthetic one first composite board 4 of hot pressing, and makes a plurality of metalworks 5 be positioned the pre-position of this first composite board 4.
In the present embodiment; Each first preimpregnation nonwoven fabric layer 3 is formed with a plurality of perforation 31; And behind synthetic this first composite board 4 of hot pressing; Just be formed with a plurality of locating holes 41 that are formed by stacking by said perforation 31 on this first composite board 4, said metalwork 5 is after treating these first composite board, 4 moulding, to be positioned respectively in the said locating hole 41 again.
This second heat-press step 22 is superimposed multilayer second preimpregnation nonwoven fabric layers 6 and carry out hot pressing on the upper and lower surface of said first composite board 4; With with said second preimpregnation nonwoven fabric layer 6 and the synthetic composite material work piece 7 of these first composite board, 4 hot pressing,, said metalwork 5 is coated in this composite material work piece 7 and being positioned.
Be noted that in the present embodiment the said first preimpregnation nonwoven fabric layer 3 and the second preimpregnation nonwoven fabric layer 6 all are composite fibre is infiltrated in the resin and forms, its structure and characteristic can be understood for those skilled in the art easily, no longer give unnecessary details.The said first preimpregnation nonwoven fabric layer 3 and the second preimpregnation nonwoven fabric layer 6 can be for carbon-fiber cloth, glass fibre be weaved cotton cloth, basalt fibre is weaved cotton cloth, or Kevlar fibers is weaved cotton cloth.In addition, be to use a plurality of metalworks 5 in the present embodiment, can certainly look actual demand and only use a metalwork 5, not as limit.
Pass through above-mentioned steps; Can said metalwork 5 be limited in the process of first heat-press step 21 in the said locating hole 41; Therefore guarantee that said metalwork 5 can not produce the displacement phenomenon because of the mobile resin of heat fusing in the said first preimpregnation nonwoven fabric layer 3; And can reach the precalculated position that said metalwork 5 accurately is positioned this first composite board 4, and then accurately be positioned the effect in this composite material work piece 7.
Consult Fig. 1,3; Second preferred embodiment for the manufacturing approach of the composite material work piece that buries metalwork in the present invention; Roughly similar aforementioned this first preferred embodiment; Difference be in: in this first heat-press step 21; Be with the said first preimpregnation nonwoven fabric layer, 3 alignment and congruences in a mould 8, this mould 8 has a male model 81 and a master mold 82, this male model 81 has the depressed part 811 of the said metalwork 5 of a plurality of correspondences; It is superimposed in this master mold 82 that layer 3 is knitted in said first preimpregnation; And said metalwork 5 placed on the said first preimpregnation nonwoven fabric layer 3 and behind the position of corresponding said depressed part 811 at interval carry out hot pressing again, make the said first preimpregnation nonwoven fabric layer 3 form these first composite boards 4 behind the hot pressing, and make said metalwork 5 receive the spacing of said depressed part 811 and be positioned the pre-position of this first composite board 4.Next the mode of this composite material work piece 7 of moulding and first preferred embodiment are similar, no longer give unnecessary details.
Whereby, utilize said depressed part 811 to reach and make said metalwork 5 accurately be positioned the precalculated position of this first composite board 4, and then accurately be positioned the effect in this composite material work piece 7, and provide the another kind of aspect of implementing to supply the user to select.
In sum, the present invention utilizes the mode of post forming to mold this composite material work piece 7, reaches whereby said metalwork 5 can accurately be positioned the effect in this composite material work piece 7, so can reach the object of the invention really.
