PROBLEM TO BE SOLVED: To provide a fiber reinforced resin product-manufacturing method and the fiber reinforced resin product, in which, in a construction including a fiber reinforced resin-made pipe, manufacturing cost reduction can be achieved through processing time shortening while weight saving of the pipe is achieved.SOLUTION: A fiber reinforced thermoplastic resin product 40 includes: a pipe 10; and a metal circular ring 16 which is connected to the pipe 10. A manufacturing method of the product 40 includes: a process in which a prepreg sheet 26 including continuous carbon fibers 25 and thermoplastic resin 27 and a stampable sheet 50 including non-continuous reinforcing fibers 51 and thermoplastic resin 52 are superimposed on each other and are heated; and a process in which both the sheets 26 and 50 are bent by press processing, a cylindrical body 28 is formed through depositing both end surfaces 26A of the prepreg sheet 26 to each other, a cylindrical body 53 is formed through depositing both end surfaces 50A of the stampable sheet 50 to each other, and both the cylindrical bodies 28 and 53 are cooled, to form a pipe 10.

    【課題】繊維強化樹脂製のパイプを含む構成において、パイプの軽量化を図りつつ、加工時間の短縮による製造コストの低減を図ることができる繊維強化樹脂製品の製造方法、および、当該繊維強化樹脂製品を提供すること。【解決手段】繊維強化熱可塑性樹脂製品40は、パイプ10とパイプ10に連結される金属円環16とを含む。当該製品40の製造方法は、連続炭素繊維25および熱可塑性樹脂27を含むプリプレグシート26と不連続強化繊維51および熱可塑性樹脂52を含むスタンパブルシート50とを重ねたものを加熱する工程と、プレス加工によって、両シート26および50を湾曲させ、プリプレグシート26の両端面26A同士を溶着させて形成した筒状体28とスタンパブルシート50の両端面50A同士を溶着させて形成した筒状体53を冷却することで、パイプ10を形成する工程とを含む。【選択図】図6
