Abstract:
A resin composition [composition (C)] comprising: from 40 to 95 % by volume (% v) of at least one aromatic polyimide [polymer (PI)], from 0.1 to 15 % by volume (% v) of at least one compound having the general formula A n X m [compound (A n X m )], wherein each A is independently selected from a group consisting of a metal atom (M) which is selected from the group consisting of Fe, Co, Ni, Cu, Zn, Mo, Ag, Cd, Sn, Pt, Au, Hg, Pb and Tl and a semimetal atom (SM) which is selected from the group consisting of As, Sb and Bi; wherein each X is independently selected from a group consisting of As, Sb, S, Se and Te; with the proviso that when A is As or Sb then X is different from A; and wherein n and m equal or different from each other, are independently 1, 2, 3 and 4, from 0.1 to 30 % by volume (% v) of at least one carbon fiber, from 0 to 15 % by volume (% v) of at least one filler selected from the group consisting of TiO 2 , ZrO 2 SiO 2 or mixtures thereof, and wherein all % are based on the total volume of the composition (C).
