SIZED GLASS STRANDS, SIZING COMPOSITION AND COMPOSITES COMPRISING THE SAID STRANDS.

摘要

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-C2, preferebly C1-C3, alkyl radical. Z represents a C1-C12 hydrocarbonaceous chain which can comprise one or more N, O and/or S heteroatoms, - and of at least one unsaturated monocilane (B) chosen from vinylsilanes and (meth) acrylocitanes. The glass strands obtained exhibit an improved ability to be cut which renders them capeble of being used to reinforce polymers, in particular by moulding by simultaneous spraying.
