  • Fibrous reinforcement suitable as a fireproofing agent
    Patent number: 7045203
    Abstract: A fibrous reinforcement including a fibrous support treated throughout or covered at least partially on one of its surfaces with a compound containing: i) one or more thermosetting prepolymers having a softening temperature of 150° C. or lower and/or one or more thermoplastic polymers having a glass transition temperature lower than 300° C.; and ii) one or more inorganic phosphorus compounds. The treatment ratio of the fibrous support with the inorganic phosphorus compound(s) falls within the range of 2%–20% by weight. The fibrous reinforcement is suitable for use as a fireproofing agent.

  • Self-adhesive prepreg face sheet for sandwich panels
    Patent number: 6508910
    Abstract: Resin compositions are provided which are used in combination with fibers to form self-adhesive prepreg sheets that are applied to core materials to form sandwich panels. The prepreg resin includes a thermoset resin, a curing agent and a viscosity control agent. The prepreg resin further includes certain thermoplastic particles which are used to control the flow characteristics of the prepreg resin and the formation of fillets during bonding of the prepreg to the core material.
