A fiber-reinforced thermoplastic resin substrate has good mechanical properties. The fiber-reinforced thermoplastic resin substrate includes a plurality of continuous reinforcing fibers and a polyphenylene sulfide resin with which the plurality of continuous reinforcing fibers are impregnated, wherein the polyphenylene sulfide resin has a weight average molecular weight of 75,000 or more and 150,000 or less, and the polyphenylene sulfide resin has an ash content of 0.001 wt % or more and 0.30 wt % or less.

Fiber-reinforced thermoplastic resin substrate

The present invention addresses the problem of providing a polyaryletherketone resin composition having excellent toughness and fluidity, a fiber-reinforced resin base material having excellent impregnating ability and toughness, and a molded article thereof. In order to solve said problem, the present invention has the following compositional make-up. A polyaryletherketone resin composition containing, with respect to (A) 100 parts by mass of a polyaryletherketone, (B) 1-100 parts by mass of a liquid crystalline polyester, wherein the polyaryletherketone resin composition forms a sea-island structure, and the average diameter of the island phases is 10-1000 nm.

Polyaryletherketone resin composition, fiber-reinforced resin base material, and molded article

A polyarylene sulfide resin composition containing nickel microparticles having an average particle diameter of 0.5 to 20 nm is produced by heating a cyclic polyarylene sulfide in the presence of at least one component selected from components (i), (ii) and (iii).
