Detailed description of the invention
In order to make technical problem solved by the invention, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
A kind of fibrous composite, with reference to shown in Fig. 7, comprising: fibrage 20, its surface has relief pattern; At least one side of fibrage 20 is evenly coated with resin bed 21, and described resin bed 21 surface is provided with the relief pattern corresponding with above-mentioned fibrage 20; Thus this fibrous composite surface has the pattern corresponding with fibrolaminar relief pattern.The present embodiment have employed and is evenly coated with resin bed 21 on the two sides of fibrage 20, and this resin bed 21 is for having the novolac epoxy resin of heat resistance.
Present invention also offers a kind of manufacture method of fibrous composite, with reference to shown in Fig. 2, the flow chart of embodiment of the present invention fibrous composite manufacture method, comprise the following steps: step one: Fiber prepreg is provided, described Fiber prepreg comprises the fibrage that surface has relief pattern, and described fibrolaminar at least one side is soaked with resin bed; Step 2: have above resin bed in Fiber prepreg and be covered with one deck separation layer; Step 3: be covered with a soft layer on described separation layer; Step 4: lead to and hot pressing is carried out to the Fiber prepreg after above-mentioned steps process; Step 5: remove soft layer and separation layer.Fiber prepreg comprises the fibrage that surface has relief pattern, after Fiber prepreg has and is covered with separation layer and soft layer above resin bed, hot pressing is carried out by hot-die, the relief pattern lines of Fiber prepreg can be made to be displayed by resin bed after hot-pressing, the fibrous composite surface manufactured has the pattern corresponding with fibrage relief pattern, thus provides comfortable feel and non-skid property.
All there is resin bed for fibrolaminar two sides below, the detailed step of fibrous composite manufacture method of the present invention be described in detail in detail:
Step one: provide Fiber prepreg, described Fiber prepreg comprises the fibrage 20 that surface has relief pattern, and described fibrolaminar at least one side is soaked with resin bed 21, and this resin bed 21 is for having the novolac epoxy resin of heat resistance.
Step 2: have above resin bed in Fiber prepreg and be covered with one deck separation layer 22; As shown in Figure 3, the epoxy resin layer of the present embodiment on two sides is covered with separation layer 22 on the surface; Separation layer 22 in the present embodiment is release liners, release liners can select PE(polyethylene, polyethylene) release liners, PET(polyethylene terephthalate, PETG) release liners, OPP(O-phenylphenol, o-phenyl phenol) one in release liners or compound release liners, because release liners just plays the effect of isolation, so its thickness gets over Bao Yuehao, existing release liners general thickness is 0.03 ~ 0.05mm, and the release liners in this thickness range can meet the demands.The area of release liners is greater than the area of Fiber prepreg, because when hot pressing, have resin and flow out, this part resin flowed out, if in release liners, is just unlikely to flow on mould.Because the content of resin in Fiber prepreg is different, the area larger than the area of Fiber prepreg 30% ~ 50% of release liners.
Step 3: be covered with a soft layer 23 on described separation layer, as shown in Figure 4; This soft layer 23 can select flexible film material, and should meet following two conditions: 1, soft, can not be broken or crack after can making bending; 2, easily sprawl, easily pave when making shaping on release liners surface.Soft layer material can be formed at the identical shape in Fiber prepreg surface with the part of Fiber prepreg surface contact when being heated, because this portion of material needs to utilize its morphotropism, so thickness can not be too thin, General Requirements is not less than 0.05mm; Simultaneously can not be too thick, if thickness is too large, the heat conduction of mould can be made to be affected, and General Requirements is not higher than 0.1mm.Certainly, if in practical condition, the lines of Fiber prepreg is very wide, can choose thicker flexible film material.The material of soft layer is thermoplastic or thermosets; Thermoplastic can select TPU (Thermoplastic polyurethanes, TPUE rubber), and this material can deliquescing under certain temperature, and can remain unchanged at normal temperatures.Thermosets can select PU(ploy urethane, polyurethane) flexible film material is used for the decorative pattern of shaping fiber prepreg cloth, so its size should be in the same size with Fiber prepreg, when placing, its position also should match with prepreg cloth position.
Because the matrix material of Fiber prepreg is generally epoxy resin, and the cementability of epoxy resin is extremely strong, because release liners is not bonding with other material, if there is no release liners, directly overlay on Fiber prepreg by flexible film material, after shaping, both will be bonded together and cause being difficult to peel off.
Step 4: hot pressing is carried out to the above-mentioned material being covered with soft layer by hot-die; Release liners and flexible film material cover good after just can put into mould 24 hot pressing, as shown in Figure 5, be the schematic diagram not carrying out hot pressing in step 4, when non-plus-pressure and temperature, release liners and flexible film material indeformable; After plus-pressure and temperature, release liners and flexible film material can be out of shape, and as shown in Figure 6, are the schematic diagrames after carrying out hot pressing in step 4.Under suitable temperature and pressure, the resin solidification in Fiber prepreg forms the shape of surface relief.Hot pressing temperature generally selects 110 ~ 160 DEG C, the pressure of hot pressing generally select 5 ~ 30 kgfs/centimetre
2; Due to the distortion of flexible film material require, so the deformation temperature of flexible film material also should at 110 ~ 160 DEG C, and flexible film material thermal degradation temperature should higher than this scope.
Step 5: removal soft layer and separation layer as shown in Figure 7, remove the structural representation after soft layer and separation layer after being step 4; After hot pressing, goods are taken out in die sinking, and flexible film material now and release liners are bonded at product surface and take out with product, and product surface does not now have irregular 3D pattern effect.The concavo-convex 3D pattern effect of product surface must be obtained after needing flexible film material and release liners to remove.The method not only can shaping two-sided 3D effect, and the above embodiments are two-sided 3D pattern effect; Also the 3D lines of one side be can form, namely release liners and flexible film material added in one side; Its step is two-sided identical with aforementioned, repeats no more herein.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
