Abstract
Disclosed herein is a melt-stable poly(arylene thioether-ketone) prepreg, which comprises in integral combination (A) 20-90 wt. % of a fibrous reinforcing material which comprises long fibers and/or at least one shaped long fiber body, said fibers and/or body being formed of inorganic fibers and/or organic fibers; and (B) 10-80 wt. % of a a thermoplastic matrix material composed principally of a melt-stable poly(arylene thioether-ketone) having predominant recurring units of the formula ##STR1## and having a melting point, Tm of 310.degree.-380.degree. C., a residual melt crystallization enthalpy, .DELTA.Hmc (420.degree. C/10 min) of at least 10 J/g, a melt crystallization temperature, Tmc (420.degree.C./10 min) of at least 210.degree. C. and a reduced viscosity of 0.2-2 dl/g. A melt-stable molded or formed product can also be obtained by shaping the above prepreg or an arrangement or laminate of prepregs of the same type as the above prepreg at 140.degree.-450.degree. C. under stresses.
