Description
Technical field
This application involves Material Fields, and in particular to the structure of composite material.
Background technique
Currently, high-intensitive to reach, low weight, thickness is thin in structure design of electron products, internal structure complexity
Purpose generallys use two kinds of different material engagements.For example, material A and material B, by taking notebook computer designs as an example, material A
Usually there is brilliant advantage in intensity, thickness and weight, but is not easy structure design, and exist to product function physically
The potential limitation of (such as antenna communication), such as material A are single layer and multi-layer board filled board material；And material B can overcome material
Problem of the matter A in material property, can be used as the extension of structure, to meet structure design requirement.In order to achieve the above objectives
It is currently used way that two kinds of materials, which are combined together,.But it also results in this and is partially formed weak intensity, and limit structure and set
Meter.And this combination most significant problems are the binding forces of two kinds of materials, generally depend on the combination method between material A and material B
With area.
Current process includes cutting plate stage, injection phase, grinding stage and spray painting stage.The cutting plate stage
It is that composite board edge is cut into concaveconvex structure；Injection phase be under injection pressure by resin intrusion plate core material in,
This stage since composite board and two kinds of resin Material shrinkage ratios are different, for realize grind spraying process after product surface still
It can keep smooth, need resin to be higher than plate surface and reserved grind, but the design of concaveconvex structure prolong plate can not
Product edge is reached, to limit the beauty of product；The grinding stage need to carry out dispensing fill two kinds of material bond areas because
The microcosmic gap shunk and formed, then being ground repeatedly makes plate members and plate members keep bond area smooth；Spray painting rank
Section is combined by the paint covering of high film thickness and is repeatedly ground repeatedly, keeps Surface Appearance smooth.
Scheme at present, since the region area that material A and material B is combined with each other is small, binding force is insufficient, after formed product,
It is easy in product surface treatment process in actual use behavior, appearance stress problem and crack phenomenon easily occur for edge；Separately
Outside, due in forming process, being easy such as to project the unequal injection condition of terminal pressure because the molding condition of existing scheme influences
It influences, causes junction uneven, lead to weak binding power.Meanwhile there is also board cost height, complex procedures.
Summary of the invention
The application provides a kind of structure of composite material.Plate can not extend to product in structure to solve composite material
The problem of edge.

Moulding process generates the styling member 2, the styling member 2 in conjunction with the step structure and with the carbon fiber unity and coherence in writing plate
The outer surface of material 16 flushes.To reduce polishing operation.
The present embodiment expands carbon fiber unity and coherence in writing plate in the usable floor area of main appearance, increases the aesthetic feeling of appearance；Drop
The low processing cost of the panel member 1 cancels the panel member 1 and is used to improve the concave-convex complex model of bond strength setting
Meter, thus simplify 1 cutter of panel member when and cost；It reduces shell and post-processes processing cost, simplify grinding Spray Painter
Sequence fills up gap caused by injection moulding plastic shrinks without dispensing, is not necessarily to grinding process；The further lighting of product shell, for example,
Carbon fiber composite board is 0.9~1.15g/cm2, because its density is generally less than 1.2~1.4g/cm of resin component2, this implementation
Example maximizes carbon fiber composite board area, and 2 area of styling member and material utilization amount are reduced, to make under integral product weight
Drop, further realizes lighting；Product integral strength is improved, carbon fiber composite board intensity itself is much larger than styling member the last 2
Degree, the usable floor area that the present embodiment has expanded carbon fiber composite board covers the surface of the panel member 1, to improve product
Integral strength；It reduces panel member 1 and cracking risk occurs in conjunction with 2 two kinds of materials of styling member, panel member 1 can be maximum
Change is extended to product edge, at this point, panel member 1 and 2 bond area of styling member are also at the edge of product shell, therefore ties
Close the problems such as region does not force bond area to be cracked vulnerable to external force influence.
Above embodiments are only the exemplary embodiment of the application, are not used in limitation the application, the protection scope of the application
It is defined by the claims.Those skilled in the art can make respectively the application in the essence and protection scope of the application
Kind modification or equivalent replacement, this modification or equivalent replacement also should be regarded as falling within the scope of protection of this application.
