Abstract:
1. A fiber-reinforced resin comprising: a fiber bundle comprising a plurality of monofilament layers being laminated, each of the monofilament layers comprising a plurality of monofilaments; and an adhesive resin adhering the plurality of monofilaments together, wherein the monofilaments have a honeycomb-shaped cross section perpendicular to a longitudinal direction of the monofilaments, wherein the monofilaments have polygonal or approximately polygonal cross sections perpendicular to the longitudinal direction of the monofilaments, wherein the monofilament layers comprises outermost monofilament layers at primary surfaces of the fiber bundle, and an intermediate monofilament layer arranged between the outermost monofilament layers, wherein the monofilaments in the outermost monofilament layers have a pentagonal or an approximately pentagonal cross section perpendicular to the longitudinal direction of the monofilaments, and wherein the monofilaments in the intermediate monofilament layer have a hexagonal or an approximately hexagonal cross section perpendicular to the longitudinal direction of the monofilaments.
