ABSTRACT:
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.
