20100112338 | Polymer film for surface coating fiber/plastics composite materials - The use of a substrate supported polymer film as a surface coating for fiber/plastics composite structures produced by the crushed core method from composite structures having a core and at least one prepreg layer, wherein the polymer film is applied to a prepreg surface with its resin side facing the surface before the composite structure is cured and optionally before it is placed in the mold, and curing is effected under applied pressure and at an elevated temperature. The substrate supported polymer film comprises a resin matrix which has a degree of crosslinking that is below its gel point, and which is produced from at least one difunctional or polyfunctional aromatic organic cyanate and at least one difunctional or polyfunctional aromatic alcohol in proportions giving a molar ratio of OCN groups to OH groups in the starting materials used for the production of the prepolymer of from 95:5 to 70:30, and which also contains at least one filler. | 05-06-2010 |
