  • Organic fibre based on an epoxy resin and a rheology-controlling agent and corresponding dry goods
    Publication number: 20070100071
    Abstract: The present invention relates to a formulation and to a process which make it possible to produce, using an epoxide resin and an agent for controlling the rheology, on the one hand, and reinforcing fibres, on the other hand, semi-finished products for composites in the form of jointly woven or knitted yarns which make it possible to prepare thermoset materials by simple heating.
    Type: Application

  • Reactive thermosetting system with long storage life
    Publication number: 20070078236
    Abstract: The present invention relates to a process which makes it possible to produce semifinished products, such as reactive textiles or films for composites, starting from two formulations, one based on epoxide resin and on a rheology-control agent and the other based on a hardener and on a rheology-control agent. These semifinished products are stable during storage but they can react together when the temperature is increased to form the desired thermoset material.
