Abstract: The invention relates to glass strands coated with an essentially aqueous sizing composition which comprises the combination of at least one bissilane (A) of formula in which: R1, R2, R3, R4, R5 and R6, which are identical or different, represent a C1-C6, preferably C1-C3, alkyl radical, Z represents a C1-C6 hydrocarbonaceous chain which can comprise one or more N, O and/or S heteroatoms, and of at least one unsaturated monosilane (B) chosen from vinylsilanes and (meth)acrylosilanes. The glass strands obtained exhibit an improved ability to be cut which renders them capable of being used to reinforce polymers, in particular by moulding by simultaneous spraying.

Abstract: The subject of the invention is glass strands coated with an essentially aqueous sizing composition which comprises the combination of at least one polyurethane A and at least one polyester B in an A/B weight ratio of less than or equal to 3, wherein the glass strands obtained are used to reinforce polymer matrices for the purpose of manufacturing translucent composites, particularly panels for lightweight roofs.

Abstract: The invention relates to glass fibers coated with an sizing composition. The said sizing composition, which is obtained in particular from an aqueous solution, comprises as bonding film-forming agents, a combination, of at least one low-molecular-weight polyvinyl acetate A, of at least one thermally self-crosslinking polyvinyl acetate copolymer B, in an A/B weight ratio greater than or equal to 1.

Abstract: A method of moulding, notably injection or compression moulding, of a composite product from an impregnation paste based upon thermosetting resin or resins and a reinforcement of glass threads, by supplying the moulds with an impregnation paste and reinforcement in the form of coated chopped direct rovings incorporated into the paste, the coating material of which includes an adhesive agent based upon polyurethane or polyurethanes.
