Prepreg, Verfahren zu seiner Herstellung und davon abgeleitete Produkte

摘要

A new prepreg material having good tack drape properties and feasible out-time and articles derived therefrom as well as processes for preparation these products are disclosed. The prepreg is prepared by impregnating inorganic fibers with a compostion comprising: (A) fine powder of a metal oxide or oxides having an average particle diameter of not larger than 1 mu m, (B) a soluble siloxane polymer having double chain structure, (C) a trifunctional silane compound having at least one ethylenically unsaturated double bond in the molecule thereof, (D) a organic peroxide, (E) a radically polymerizable monomer having at least two ethylenically unsaturated double bonds; and heating the impregnated fibers.
