  • Patent number: 7556853
    Abstract: The invention relates to a material with high fracture toughness based on a vinyl ester resin and/or on an epoxide resin and to its process of manufacture. This material comprises at least one polymerized resin chosen from vinyl ester resins and epoxide resins which can be polymerized at a temperature of less than 70° C. and their blends, and a thermoplastic adjuvant present in this resin in the form of particles, and exhibits a fracture toughness (KIc) of greater than or equal to 1.2 MPa·m1/2 as determined according to Standard ISO 13586:2000. It also relates to a composite material comprising a matrix composed of said material and a reinforcement. Applications: automobile, railway, ship-building, aeronautical, aerospatial and other industries.
    Type: Grant

  • Patent number: 6187123
    Abstract: The present invention concerns a method for producing a lightened SiC structure, especially for the production of a lightened mirror, with the following stages: cutting of a preform with a honeycomb-shaped structure whose voiles have an organic matrix and a fibrous reinforcement, pyrolysis of this honeycomb-shaped structural preform so as to solely preserve the carbon, silicidation of the carbon of the preform so as to obtain a microporous SiC core, infiltrating type reinforcement by means of a SiC chemical vapor phase depositing of the voiles of the honeycomb structure of the core, embodiment of a felt sheet and assembling on at least one face of the core of the embodied sheet and densification of this sheet so as to obtain at least one SiC skin on the surface of the core. The invention also concerns the structure obtained.
