    • A phosphosiloxane resin comprises a plurality of covalently bonded monomer units selected from phosphosiloxane units SiR23—O—P(═O)(R1)(OR3)q(O1/2—)p, and organosiloxane units R2m(OR3)nSiO(4-m-n)/2. R1 and each R2 are independently selected from the group consisting of hydrogen, C1 to C10 hydrocarbyl, and C1 to C10 hydrocarbylene; each R3 is independently selected from the group consisting of hydrogen and C1 to C10 hydrocarbyl; p is 0 or 1; q=1−p; m is 0, 1, 2, 3, or 4; n is 0, 1, or 2; and m+n is 0, 1, 2, 3, or 4. Curable silicone compositions comprise a phosphosiloxane resin having greater than one silicon-bonded alkenyl group, an organosilicon compound having at least two silicon-bonded hydrogen atoms, and a hydrosilylation catalyst. Fiber-reinforced free-standing films may comprise fibers dispersed in a cured product of the silicone composition. Laminated substrates comprise at least one fiber-reinforced free-standing film.
    • 磷硅氧烷树脂包括选自磷硅氧烷单元SiR23-OP(= O)(R1)(OR3)q(O1 / 2-)p和有机硅氧烷单元R2m(OR3)nSiO(4-mn))的多个共价键合的单体单元, / 2。 R 1和R 2各自独立地选自氢,C 1至C 10烃基和C 1至C 10亚烃基; 每个R 3独立地选自氢和C 1至C 10烃基; p为0或1; q = 1-p; m是0,1,2,3或4; n为0,1或2; 并且m + n为0,1,2,3或4.可固化的硅氧烷组合物包含具有大于一个硅键合的烯基的磷硅氧烷树脂,具有至少两个与硅键合的氢原子的有机硅化合物和氢化硅烷化催化剂 。 纤维增强的自立膜可以包括分散在硅氧烷组合物的固化产物中的纤维。 层压基材包括至少一种纤维增强的自立膜。
