A composite material member having an FRP layer made of fiber-reinforced plastic, and a resin-rich layer that has a fiber content that is 5% or less of the fiber content of the FRP layer. The resin-rich layer is formed in at least a partial region of a surface of the FRP layer, and is formed from the same resin as a matrix resin of the fiber-reinforced plastic. A hole is bored so as to penetrate the FRP layer and the resin-rich layer.

A sheet material processing device 3 for performing processing on a having-been-conveyed sheet material along a direction perpendicular to the conveyance direction of the sheet material, includes: a blade member 4 including an upper blade part 42 and a lower blade part 41 that extend in the perpendicular direction and then pressing both blade parts 41 and 42 to each other so as to perform predetermined processing on the sheet material located between both blade parts; a pressing mechanism 5 for pressing both blade parts to each other; and a moving mechanism 6 for moving the blade member in the perpendicular direction, wherein in the upper blade part 42, a processing blade 421 is formed at one or more sites in the perpendicular direction, and wherein in the lower blade part 41, a receiving part for the processing blade is formed over the section facing the processing blade 421.

A separating device for separating individual container products from a frame assembly of plastic material, particularly polypropylene, has at least one stamping device (36) that at least partially separates the respective container product from a frame waste. By the stamping device (36) including a free fall body (52) separating the respective frame waste from the associated container product from an initial position during free fall, the separation can be carried out with very high speed (free fall) and additional mechanical components for applying a constraint force on the stamping body during the creating of the separating line can be omitted.
