Embodiment
Below the present invention is described in detail.
Fibre reinforced composites of the present invention are that kevlar fabric is used as fortifying fibre by the manufacture method of Aramid Prepreg, silicon rubber is used as matrix resin, and be divided into following four steps.
(A) prepare coupling agent
At first the present invention is that kevlar fabric and matrix resin are the consistency of silicon rubber for strengthening with fortifying fibre, prepares to intend the silane water-based coupling agent flooded on described kevlar fabric.Originally silane coupling agent is to develop for the consistency between reinforcing glass fiber and the matrix material that forms with the organic resin thing, but, along with the development of various matrix materials, has been widely used in the bounding force strengthened between organic materials and inorganic materials.Especially recently except simple adhesive function, also the characteristic such as heat-resisting in order to give, water-fast, electricity and magnetic properties, improvement processibility, strongthener intensity, increased various functions.
The silane water-based coupling agent that the present invention uses is preferably, for from the n-(2-amino-ethyl)-3-TSL 8330,3-(glycidyl ether oxygen base propyl group methyldiethoxysilane), select 3-methyl allyl acyloxypropyl trimethoxysilane and 3-sulfydryl propyl trimethoxy silicane some more than silane compound 100 weight parts, by acetic acid 30-50 weight part and water 800-900 weight part, formed.
Described silane compound all has water-soluble, in water, be easy to dissolve, but described acetic acid has the water miscible function that strengthens silicon fusing compound.Therefore to silane compound 100 weight parts, less than 30 weight parts, silane compound can not be dissolved in water to the content of described acetic acid fully, otherwise surpasses 50 weight parts, and the pH of described silane water-based coupling agent can become too high.
Described water is as by silane compound medium of coating equably on fabric, and its content is lower than 800 weight parts, and the concentration of silane compound is too high and failure costs surpasses 900 weight parts on the contrary, has the problem of silane compound treatment effect deficiency.
(B) dipping, extruding
Then, after the strong thing of dipping aramid fiber, use 3.5-4.5kg/cm in above-mentioned silane water-based coupling agent
2the mangle roller of pressure is pushed.
