Description
Technical field
The present invention relates to a kind of composite and its manufacture method, more particularly to a kind of lightweight
Composite and its manufacture method.
Background technology
Carbon fiber is the sheathing material of existing market main flow, with high intensity, hardness height, corrosion resistant
The advantages of erosion etc., it is common to use in bicycle rack, notebook computer, glof club head etc.
Product category.However, the density of carbon fiber is about in 1.5g/cm3To 2g/cm3Between, it is directed to
In the market for the lightweight requirements of each product, the density of carbon fiber still dislikes too high, therefore phase
Pass field pursuer is all directed to the composite of this demand active development carbon fiber.
Refering to Fig. 1, it is an existing material shell 1, is made comprising one with expanded material
And honeycomb-like core 11, and two opposite sides for being respectively arranged at the core 11 carbon
Fibrous layer 12.The density of described material shell 1 is 1.15g/cm3, compared to pure carbon
For fiber, density value has declined to a great extent.
The manufacture method of the material shell 1, is first to be made after the core 11, utilizes carbon
Fiber prepreg is attached at the opposite sides of the core 11, then in hot-forming mode,
Make the thermosetting resin consolidation of advance immersion contained in the carbon fibre initial rinse fabric, and be shaped to
The carbon fiber layer 12.
But, although the material shell 1 have the density low compared with pure carbon fiber, but by
The carbon is being molded in hot-forming mode with hole in honeycomb in the core 11
During fibrous layer 12, it is difficult to control the thermosetting resin to fill the situation of the hole of core 11,
When the thermosetting resin fill the hole of core 11 it is out of condition when, then can cause the core
The adhesion of material 12 and the carbon fiber layer 12 is deteriorated.Also due to the situation of filling is difficult to control to,
Therefore the unstable situation of the manufacture quality of the material shell 1 can be caused.Therefore, how to make
Produce that density is lower, bond strength preferably, and the relatively stable composite of manufacture quality, then
The problem of solution is desired most ardently as association area pursuer.
The content of the invention
It is compound it is an object of the invention to provide the lightweight that a kind of density is low and bond strength is good
Material.
Lightweight composite of the present invention, has two surfaces for being respectively facing opposite side comprising one
The first base material, and one be formed at the first base material a wherein surface the first carbon fiber layer.Its
In, the first base material is to be mixed with glass fiber material made by several hollow glass balls, is coordinated
First carbon fiber layer, can form that density is low and lightweight composite of high intensity.
The object of the invention to solve the technical problems can also be further using following technical measures
Realize.
It is preferred that foregoing lightweight composite, wherein also comprising second carbon fiber layer,
It is formed at another surface of the first base material.
It is preferred that foregoing lightweight composite, wherein also comprising second base material, with glass
Glass fibrous material is mixed made by several hollow glass balls, is formed at first carbon fiber layer remote
The side of the first base material.
It is preferred that foregoing lightweight composite, wherein also comprising two table material layers, difference
It is formed at side of the first base material with second base material in contrast to first carbon fiber layer.
It is preferred that foregoing lightweight composite, each of which table material layer is with carbon fiber
Made by material.
It is preferred that foregoing lightweight composite, the density of each of which hollow glass ball is
0.2g/cm3To 0.6g/cm3。
The present invention also aims to provide it is a kind of make the relatively stable lightweight of manufacture quality answer
The manufacture method of condensation material.
The manufacture method of lightweight composite of the present invention, sequentially comprising a material preparation step, a patch
Attached step, and a forming step.The material preparation step is that several hollow glass balls and resin is leading
Mixing, and it is coated on two surfaces of a glass fiber woven cloth；The attaching step is by two carbon
Fiber prepreg is attached at two surfaces of the glass fiber woven cloth respectively, formed half into
Product；And the forming step is that the semi-finished product are carried out with hot pressing, make the glass fiber woven cloth and institute
State carbon fibre initial rinse fabric to be together molded, a lightweight composite is made.
In addition, the manufacture method of lightweight composite of the present invention, also can be sequentially standby comprising one
Expect that step, one first attach step, a stacking procedure, and a forming step.The material preparation step
It is to mix several hollow glass balls with resin in advance, and is coated on multiple glass fiber woven cloths
Two surfaces；The first attaching step be multiple carbon fibre initial rinse fabrics are attached at respectively it is described
A wherein surface for glass fiber woven cloth, formation is multiple to treat stackable unit；The stacking procedure is
Stackable unit layer stack each other is treated described in making, a semi-finished product are formed；And the forming step is pair
The semi-finished product carry out hot pressing, make the glass fiber woven cloth and the carbon fibre initial rinse fabric together
Shaping, is made a lightweight composite.
The glass fiber woven cloth of hollow glass ball and resin is coated with, with the carbon fibre initial rinse fabric
Together after hot pressing, can closely it be bonded to each other.Moreover, due to glass fiber material hybrid resin
And after hollow glass ball, will not have hole such as foaming material, therefore hot-forming
When, will not occur because pore filling is difficult to control to and caused by the unstable situation of quality.
The object of the invention to solve the technical problems can also be further using following technical measures
Realize.
It is preferred that the manufacture method of foregoing lightweight composite, the wherein semi-finished product have two
The surface of the opposite side of individual direction, the manufacture method also comprising one before the forming step second
Step is attached, a carbon fibre initial rinse fabric is attached at least one surface of the semi-finished product.
It is preferred that the manufacture method of foregoing lightweight composite, each of which double glazing
The density of ball is 0.2g/cm3To 0.6g/cm3。
The beneficial effect of the present invention is：The first base material is with low density hollow glass ball
Coordinate made by glass fibre material, due to the low-density characteristic of the hollow glass ball, with combined glass
The high-strength characteristic of glass Fiber Materials, carbon fibre materials, therefore thus can make the lightweight composite wood
Performance of the material with lightweight and high intensity.And pass through the manufacturer of the lightweight composite
Method, then can produce the lightweight composite of stay in grade.
