Abstract
Resin compositions having excellent mechanical strength, especially at high temperatures are disclosed. The resin compositions comprise 95-60 wt. % of an aromatic polyetherketone having recurring units represented by the following formula: ##STR1## 5-40 wt. % of a polyetherimide having recurring units represented by the following formula: ##STR2## Also disclosed are fiber-reinforced resins, which comprise 75-55 wt. % of one of the above compositions and 25-45 wt. % of carbon fibers obtained by coating starting carbon fibers with an aromatic polysulfone resin and then heating the thus-coated carbon fibers at 300.degree.-400.degree. C., and mechanical components made of desired one of the fiber-reinforced resins which are suitable for use in internal combustion engines or auxiliary equipment.
