Abstract
The invention provides a carbon fiber prepreg with thermosetting epoxy resin used as a matrix and a preparation method thereof. The carbon fiber prepreg is formed by two steps: a primary prepreg comprises a reinforced fiber matrix and is formed by immersing the reinforced fiber layer into an epoxy resin composition composed of epoxy resin, thermoplastic resin and a curing agent; and the formed primary prepreg and an epoxy resin soluble thermoplastic resin composition which contains epoxy resin and is dissolved in epoxy resin undergo multilayer compression molding by a hot rolling method so as to finally prepare the prepreg which meets performance requirements. By multilayer compression molding to obtain the carbon fiber prepreg, impact resistance and interlaminar toughness of the thermosetting resin matrix carbon fiber prepreg can be remarkably enhanced.
Description
Technical field
It is the carbon fiber prepreg and preparation method thereof of matrix that patent of the present invention relates generally to thermosetting epoxy resin, and the carbon fiber prepreg of gained is mainly used as the enhancing of matrix material.Because it adopts the manufacture craft of Multi-layer thermal roll-in, gained finished product can significantly improve the performance of thermosetting resin matrix carbon fiber prepreg in impact resistance and interlaminal toughness.
Background technology
Carbon fiber and matrix material thereof, because of over-all properties and the high added value of its excellence, be referred to as " the black gold " of 21st century by people.In actual applications, carbon fiber is usually used as fortifying fibre, by carbon fiber reinforced matrix material, there is high strength, high rigidity and light-weighted characteristic usually, extensively utilized in modern industry thus, as fields such as aerospace, automobile, boats and ships heavy industry and deepwater oilfields.Along with whole world science and technology and the progress of production technique and the expansion of Application Areas, also more and more higher to the requirement of material property, and become with the carbon fiber prepreg that carbon fiber is main strongthener the study hotspot that current matrix material strengthens field.
As the class intermediate materials being widely used in composite fiber enhancing design and manufaction technique, carbon fiber prepreg is exactly laminated material matrix resin dipping being made in the carbon fibers sheet, being the product do not reached before solid state that a kind of fiber is prepared by corresponding overlapped way and technique to resin, is the work in-process that carbon fiber product often uses.As the intermediate materials that matrix material is important, the performance of prepreg directly has influence on the quality of composite property, therefore requires that carbon fiber prepreg also should have the performance advantages such as good toughness and modulus except self having excellent adhesive property.For the design of matrix material, prepreg is the structural unit with certain mechanical property, is therefore necessary very much that the deficiency to existing in carbon fiber prepreg is improved.
As the representative of thermosetting resin, epoxy resin is because of its good physical and chemical performance, dielectric properties, modification shrinking percentage is little, product size good stability, hardness is high, the high shaping degree of freedom of tackiness and drape is high, to the performance that alkali and most of solvent-stable etc. are excellent become prepare carbon fiber prepreg can top-priority body material.But due to thermosetting resin under normal circumstances comparatively thermoplastic resin show as low toughness, impact resistance is all lower under normal circumstances for the matrix material thus prepared for strongthener by it.The existing method improving matrix material impact resistance and interlaminal toughness mainly dissolves the thermoplastic resin dissolving in thermosetting resin in thermosetting resin, is improved impact resistance and the interlaminal toughness of matrix material by the high tenacity of thermoplastic resin.
Summary of the invention
The object of the invention is for solving thermosetting resin matrix carbon fiber prepreg impact resistance and the lower problem of interlaminal toughness, provide a kind of prepreg that can make impact resistance and the high polymer composite of interlaminal toughness with and preparation method thereof.
In order to solve the problem and be met the material of respective performances, realize by following technique means: immerse in carbon fiber layer in the resin combination that thermosetting epoxy resin, thermoplastic resin and solidifying agent are formed and be prepared into a prepreg; Prepreg is laid in containing epoxy resin and be dissolved in epoxy resin epoxy resin soluble thermoplastic resin film between, by hot-rolling method by the prepreg formed and the prepreg finally being met performance requriements containing epoxy resin and the epoxy resin soluble thermoplastic resin combination multilayer compression moulding that is dissolved in epoxy resin.Concrete operations are as follows:
First, each moiety as shown in following table two is mixed 40 ~ 45 minutes by stirrer at 90 DEG C ~ 100 DEG C, prepares composition epoxy resin A and composition epoxy resin B respectively.This composition epoxy resin A and composition epoxy resin B is coated on mould release film with film coater respectively, obtains Resin A film and resin B film.
Secondly carbon fiber bundle is evenly arranged between double-layer films A with the amount of mass area ratio 195g/ ㎡ ~ 205g/ ㎡ along one direction, and with roller with 11 ㎏/㎝ ~ 13 ㎏/㎝, 125 DEG C ~ 135 DEG C pressurizations and heating, obtains a prepreg.
Then a two-layer prepreg is placed between three-layer resin film B respectively, and uses roller with 2.0 ㎏/㎝ ~ 2.2 ㎏/㎝, 80 DEG C ~ 85 DEG C pressurizations and heating, obtain prepreg.
The thermoset carbon fiber prepreg obtained according to the present invention has excellent impact resistance and high interlaminal toughness, improving the performance of thermosetting resin carbon fiber prepreg, improve with thermoset carbon fiber as strengthening the use properties of the matrix material of intermediate layer material.

Below by specific embodiment, foregoing of the present invention is illustrated, but following embodiment does not limit the scope of the invention.
