  • Two part sizing composition for coating glass fibres and composite reinforced with such glass fibres
    Patent number: 9758430
    Abstract: The present invention concerns a two-part sizing composition comprising: (A) A precursor comprising: (a) An aminosilane (e.g. A1100) and (b) a polymer or copolymer containing carboxylic acid and/or anhydride, both having a functionality, F?3, and (B) A binder comprising a multi-functional epoxy resin of functionality, F?3. Glass fibres sized with the reaction product of the above composition yield a higher resistance to hydrolysis of polymeric matrix composite materials reinforced with such fibres. The sizing composition of the present invention is particularly advantageous for use with polyester resins, such as PET.
