摘要： The invention aims to provide a tape-shaped prepreg including unidirectionally oriented reinforcing fibers and a thermoplastic resin composition and being high in handleability during molding and high in adhesiveness to other members. The tape-shaped prepreg includes unidirectionally oriented reinforcing fibers and a thermoplastic resin composition and has an arithmetic average roughness (Ra) of 0.1 to 10 μm in a direction perpendicular to the orientation direction of the reinforcing fibers, as measured according to JIS B 0601: 2013, and a warpage rate of 5% or less as determined by the procedure specified in (i) to (iii) below: (i) place a test piece of the above tape-shaped prepreg having a length of 100 mm in the fiber orientation direction on a plane in such manner that the end portions curl upward, (ii) measure the vertical distance from the highest position at the right end of the curled tape to the plane, which is denoted by a, and the vertical distance from the highest position at the left end to the plane, which is denoted by b, and calculate the arithmetic average of a and b, which is defined as the warpage distance, and (iii) calculate the warpage rate by the following equation: warpage rate (%)=warpage distance (mm)/100 (mm)×100.

摘要： Provided are a process and an apparatus for producing a fiber-reinforced thermoplastic resin tape, the process and the apparatus being capable of preventing fiber cut from occurring at the start of production of the fiber-reinforced thermoplastic resin tape. The provided process includes a resin impregnation step of opening a fiber bundle and impregnating the fiber bundle with molten thermoplastic resin and a through-nozzle passing step of passing the fiber bundle having undergone the resin impregnation step through a slit formed in a nozzle. The through-nozzle passing step includes setting, at the start of production, a gap dimension of the slit to a dimension larger than a normal dimension and changing the gap dimension of the slit to the normal dimension when a predetermined condition is satisfied, after the production start.
