摘要:
The present invention contemplates a method for forming a reformable epoxy resin material into a fiber format and: (i) weaving the reformable epoxy resin material (10) with a reinforcing fiber (12) to form a woven material; (ii) stitching a secondary material (14) with reformable epoxy resin material; and optionally (iii) forming a web or mesh with the reformable epoxy resin material.
摘要:
The present invention concerns a process for the production of injection moulded glass fibre reinforced composites from extruded glass fibre reinforced pellets, said process comprising the following steps: (A) Providing: (a) Glass fibres (2) coated with a silane based sizing composition, said silane based sizing composition comprising at least one sizing reactive moiety, A1, A2, , (b)A thermoplastic matrix polycondensate (2) comprising a first matrix reactive moiety, B1, at a first end of the chain and a second matrix reactive moiety, B2, at a second end of the chain, , (c) A salt (3) selected among an internal lubricant and a nucleating agent comprising a salt reactive moiety, C, capable of reacting with the at least one sizing reactive moiety, A1, A2, and/or with the first or second matrix reactive moiety, B1, B2, said salt reactive moiety, C, being selected among, • A metallic cation , • An organic portion having a functionality, f = 1, with a reactive moiety selected among the anionic form of a carboxylic group or a hydroxyl group, and • An inorganic anion such as carbonate or sulphate,
(B) Blending the glass fibres, thermoplastic matrix polycondensate, and salt; (C) Forming glass fibre reinforced pellets; and (D) Injection moulding a composite part with a composition comprising the reaction product of said glass fibres, thermoplastic matrix polycondesate and salt
Characterized in that, the salt is added to a blend of thermoplastic matrix composite and glass fibres only after the first and/or second matrix reactive moieties, B1, B2, and the at least one sizing reactive moiety, A1, A2, are given time to react together at least partially.

An aqueous binder composition for mineral fibers comprises:
a water-soluble binder component obtainable by reacting at least one alkanolamine with at least one carboxylic anhydride and, optionally, treating the reaction product with a base; and at least one hydrolytic stability-improving agent selected from monoalkanolamines; allylamines; peroxy compounds; epoxy compounds; compounds having at least one long-chain aliphatic moiety and at least one functional group; and SBR latices.
摘要:
A finishing composition and method for applying the composition to a fabric (10) woven from glass fibers or from a blend of glass fibers and other fibers such as polyamide or polyester. Such finishes significantly enhance the flex life of woven glass fabrics (10) by improving the acid and alkali corrosion resistance of the fibers. The finish, which comprises fluoropolymer and epoxy resin, can be loaded into the fabric in multiple baths (11). Filtration products can be fabricated from the finished fabrics and they are especially useful for making filter bags (1) used in the bag houses (2) for central power generating stations and similar industries.
