The objective of the present invention is to provide a polyarylketone resin composition, a fiber-reinforced resin base material, and formed products therefrom having excellent thermal stability and mechanical properties. In order to achieve the above objective, the present invention has the following constitution. That is, the polyaryletherketone resin composition comprises (A) a polyaryletherketone and (B) a transition metal compound, wherein the transition metal content is between 0.001 parts by mass and 4 parts by mass inclusive with respect to 100 parts by mass of (A) the polyaryletherketone.

Polyaryletherketone resin composition, fiber-reinforced resin base material, and formed product

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).
