ABSTRACT:
The invention relates to a composition of polymerizable resins reinforced with cut yarns of different lengths, such as glass yarns, and a process for its production. This composition comprises at least a representative of each of the following constituents: an unsaturated polyester, a thermoplastic polymer, a monomer liquid substance having at least a polymerizable reactive CH.sub.2 .dbd.C< group per molecule, an inert filler and optionally a thickening agent, a catalyst, an inhibitor and a releasing agent, the cut yarns being in the dispersed state in filament form for the longest ones, with the shortest yarns remaining in state of yarn formed from a multiplicity of filaments glued together. The process steps include making the mixture of the organic constituents and successively incorporating therein first the yarns previously coated with an insoluble lubricant, then the yarns coated with a lubricant which is soluble in the mixture. The compositions according to the invention may be used to make composite products by injection or compression molding.
