Abstract: The invention relates to a sheet molding compound comprising a thermosetting resin and a fibrous structure bonded by a solvent soluble in said thermosetting resin. During manufacture by hot compression molding of the composite, the binder dissolves and frees the fibers of the fibrous structure, allowing the structure to flow and fill the entire mold for manufacturing the composite. A fibrous structure containing continuous strands or chopped strands may be used. The binder allows the fibrous structure to be handled, wound and stored before it is incorporated into the sheet molding compound.

Abstract: A method for reinforcing materials already in place in the ground using fibrous additives.

Abstract: A material intended to form grounds, layers or sublayers of terrains or of carriageways.It contains an ungraded granulated material such as sand or pulverulent materials of industrial origin to which bundles of glass filaments are added in a proportion from 0.01 to 0.1%.

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.
