Abstract

The invention provides a shell, which substantially comprises a composite fiber body and an elastic layer combined on the composite fiber body. A plastic body is combined on the elastic layer. According to the technical scheme, the shell can save resources and is sturdy, durable, light and portable.

Description

A kind of housing

Technical field

The present invention relates to field of materials, relate in particular to a kind of housing.

Background technology

Nowadays, the research and development of the housing of articles for use such as mobile phone, electrical equipment, computer have obtained significant progress, and in the prior art, traditional housing is a metal material, or plastics.Yet, heavier though metal material is firm, the metals resources of consume valuable, and not portable; And plastics are thicker, and are firm inadequately again, are subject to the influence of environment and produce distortion, perhaps can become flexible, and perhaps can be pressed onto inner circuit or parts.

Summary of the invention

To aforesaid technical problem, the purpose of this invention is to provide a kind of more firm light housing.

The objective of the invention is to realize through following technical scheme:

A kind of housing comprises:

The composite fiber body is combined in the elastic layer on the composite fiber body, on elastic layer, is combined with plastic body.

Further, the composite fiber body is thermosetting fibre body or thermoplastic fibre body.

Further, the fiber in the composite fiber body is long fibre or short fiber.

Further, elastic layer comprises thermoplastic elastomer (TPE).

Further, thermoplastic elastomer (TPE) comprises polyurethane resin or polyamide.

Further, elastic layer comprises thermoplastic elastomer (TPE) and hot melt colloid.

Further, plastic body comprises polyamide, is mixed with in the polyamide, polycarbonate resin, acrylic diglycol carbonates resin, plexiglass of glass fibre or carbon fiber one or more.

Further; The combination of composite fiber body, elastic layer and plastic body is: after composite fiber body and elastic layer are combined as a whole through heating and pressurization; Combine with plastic body; Perhaps, composite fiber body that adds elastic layer and the plastic body that adds elastic layer are combined as a whole through heating and pressurization.

Further, the number of plies of elastic layer is an individual layer, and perhaps the number of plies is a multilayer.

Use technical scheme of the present invention, can not use metal, also can overcome the defectives such as rigidity deficiency of only using plastics to bring, can economize on resources, housing is sturdy and durable and light.

The specific embodiment

For make the object of the invention, technical scheme, and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, to further explain of the present invention.

Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, the present invention provides a kind of housing, comprising:

Composite fiber body 1 is combined in the elastic layer 2 on the composite fiber body 1, on elastic layer 2, is combined with plastic body 3.

Illustrate the housing advantage of this structure, like mobile phone, the casing of mobile phone generally is a metal, and the plain casing of metal is too heavy, waste resource, and conduction.The casing that electrical equipment is perhaps arranged is the composite fiber body and the combining of plastic body.General composite fiber body and plastic body need the long period to react, and carry out bonding.Also have and use the composite fiber body fully, little but shortcoming is a success rate, cut out the joint portion with computer and lose time very much, burr are many.Therefore, through using the combination of three kinds of materials, can overcome above-mentioned shortcoming.The composite fiber body is firm light, combines plastic body promptly can form perfectly housing again.Such housing can apply to make the shell of mobile phone, electrical equipment, also can be used to make the gadget of sporting goods, on the pedal like bicycle, can also be used at the big end of bicycle footwear.

Further, composite fiber body 1 is thermosetting fibre body or thermoplastic fibre body.

Further, the fiber in the composite fiber body 1 is long fibre or short fiber.Long stapled strength ratio is better, and on short fiber can be used for not requiring that too high-intensity accessory is made, and short fiber is cheaper than long fibre price.

Further, elastic layer 2 comprises thermoplastic elastomer (TPE).Thermoplastic elastomer (TPE) is the elasticity that has rubber under the normal temperature, and at high temperature has one type of elastomer of plasticization moulding.

Further, thermoplastic elastomer (TPE) comprises polyurethane resin or polyamide.Polyurethane resin has good oil resistivity, toughness, wearability, resistance to ag(e)ing and cohesive.That polyamide has is nontoxic, light weight, good mechanical strength, wearability and corrosion resistance preferably, and its film thickness of processing is thinner, only 0.05 millimeters thick.

Further, elastic layer 2 comprises thermoplastic elastomer (TPE) and hot melt colloid.The hot melt colloid can carry out reinforcement to thermoplastic elastomer (TPE).Go on the sporting goods, increase twisting resistance.

Further, plastic body 3 comprises polyamide, is mixed with in the polyamide, polycarbonate resin, acrylic diglycol carbonates resin, plexiglass of glass fibre or carbon fiber one or several.The polyamide intensity that is mixed with glass fibre or carbon fiber is better than polyamide, and high temperature resistant.

Further; Composite fiber body 1, elastic layer 2 with the combination of plastic body 3 are: after composite fiber body 1 is combined as a whole through heating and pressurization with elastic layer 2; Combine with plastic body 3, the integral body that this combination is fit to more frivolous, small-sized housing combines and manufacturing.Perhaps, composite fiber body 1 that adds elastic layer 2 and the plastic body 3 that adds elastic layer 2 are combined as a whole through heating and pressurization.This mode relatively is fit to the manufacturing of big part finished product housing.

Plastic body 3 among the above embodiment can be to penetrate promptly to combine with elastic layer 2 with the injection moulding mode.

Further, the number of plies of elastic layer 2 is an individual layer, and perhaps the number of plies is a multilayer.Individual layer can be more frivolous, and multilayer then intensity is good.

More than a kind of housing that the embodiment of the invention provided has been carried out detailed introduction, used concrete example among this paper principle of the present invention and embodiment set forth, the explanation of above embodiment just is used for helping to understand core concept of the present invention; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that on the specific embodiment and range of application, all can change, to sum up, this description should not be construed as limitation of the present invention.
