| 摘要 |
The invention relates to a fibrous reinforcement, particularly for the production of composite pieces, comprising a fibrous support either core-treated or at least partially covered on one of the faces thereof with a composition comprising: i) one or several thermosetting prepolymers with a softening temperature of </= 150 DEG C, preferably within the range of 50 to 100 DEG C and/or one or several thermoplastic polymers with a glassy transition temperature < 300 DEG C, preferably within the range of 50 to 200 DEG C and ii) one or several inorganic phosphorous compounds, preferably of phosphorous red. The rate of treatment of the fibrous support with said inorganic phosphorous compound(s) is in the range of 2 to 20 % by weight, preferably in the range of 4 to 12 % by weight, more preferably in the range of 6 to 10 % by weight and the thermosetting prepolymers and/or the thermoplastic polymers represent 1 to 6 % of the total weight of the fibrous reinforcement. The invention further relates to a method for production of such a fibrous reinforcement and the use thereof as a fire-resistant agent. |
