Abstract
Official abstract text for this publication.
A fiber reinforced thermoplastic resin member is formed by impregnating continuous fibers with a thermoplastic resin. As surfaces of the fiber reinforced thermoplastic resin member, surface layers are provided which are formed of a thermoplastic resin having a higher molecular weight than the thermoplastic resin.
First claim
Opening claim text (preview).
1 . A fiber reinforced thermoplastic resin member formed by impregnating continuous fibers with a thermoplastic resin and comprising, as a surface of the fiber reinforced thermoplastic resin member, a surface layer formed of a thermoplastic resin having a higher molecular weight than an interior thermoplastic resin. 2 . The fiber reinforced thermoplastic resin member according to claim 1 , wherein the interior thermoplastic resin has a number average molecular weight Mn of 50,000 or less. 3 . The fiber reinforced thermoplastic resin member according to claim 1 , wherein the surface layer has a thickness of 100 μm or less. 4 . The fiber reinforced thermoplastic resin member according to claim 2 , wherein the surface layer has a thickness of 100 μm or less. 5 . The fiber reinforced thermoplastic resin member according to claim 1 , wherein the surface layer is formed of a thermoplastic resin that is similar to the interior thermoplastic resin and that has a higher molecular weight than the interior thermoplastic resin. 6 . The fiber reinforced thermoplastic resin member according to claim 2 , wherein the surface layer is formed of a thermoplastic resin that is similar to the interior thermoplastic resin and that has a higher molecular weight than the interior thermoplastic resin. 7 . The fiber reinforced thermoplastic resin member according to claim 3 , wherein the surface layer is formed of a thermoplastic resin that is similar to the interior thermoplastic resin and that has a higher molecular weight than the interior thermoplastic resin. 8 . The fiber reinforced thermoplastic resin member according to claim 4 , wherein the surface layer is formed of a thermoplastic resin that is similar to the interior thermoplastic resin and that has a higher molecular weight than the interior thermoplastic resin.
