Procedimiento para la produccion de un material compuesto o un precursor del mismo, que comprende impresión de un material de soporte con una tinta (d) curable por irradiacion con luz, curado de la tinta (d), impregnacion del material de soporte asi tratado con una resina curable (b) y curado de la resina (b); material compuesto o precursor del mismo.

摘要

A process for producing a composite material or a precursor thereof includes the steps: (i) printing a support material (A1) with an ink (D) which can be cured by irradiation with light, the support material (A1) (a) being impregnable with a curable resin (B) which after curing is transparent and light-stable, and (b) having a translucency, based on the overall thickness, of 10-95%, preferably 20-90%, more preferably 30-80% for light in the wavelength range of 200-500 nm; (ii) curing the ink (D) by irradiation with light; (iii) impregnating the thus-treated support material (A1) with a curable resin (B) which after curing is transparent and light-stable, and optionally combining the support material (A1) with at least one further support material (A2); and (iv) curing the curable resin (B) simultaneously with or after step (iii); and also relates to the material obtainable by this process.
