    摘要： The purpose of the present invention is to achieve at least one of the following: preventing contamination of SMC manufacturing line, maintaining the cleanliness of mechanical elements included in SMC manufacturing apparatus, preventing failure of control equipment installed in or around SMC manufacturing apparatus, and preventing deterioration of working environment. The method of manufacturing a sheet molding compound, comprises (i) allowing short fiber bundles to fall onto a travelling carrier film, while dispersing the short fiber bundles using a dispersion roller device, thereby depositing a fiber mat on the carrier film, and (ii) impregnating the fiber mat with a thermosetting resin composition, wherein the dispersion roller device has a rotationally driven dispersion roll, bearings, a first side cover, and a second side cover, wherein the dispersion roll comprises a roll body and roll body-adjoining parts, and an inner circumferential surface of a circular opening provided in each of the first and second side covers and a cylindrical circumferential surface of each of the roll body-adjoining parts face each other.

    摘要： A fiber-reinforced composite molded article which is obtained by molding reinforcing fibers and an epoxy resin, while containing a silicone oil as an internal mold release agent, and which is characterized in that the fragment ion intensity ratio A/B as detected in case where the molded article surface is analyzed by time-of-flight secondary ion mass spectrometry is expressed by the relationship of 3 ≤ A/B ≤ 20. A: The intensity of a fragment ion that has the highest intensity among the fragment ions derived from the silicone oil. B: The intensity of a fragment ion that has the highest intensity among the fragment ions derived from the epoxy resin. A fiber-reinforced resin molded article according to the present invention is capable of achieving high productivity and high quality by effectively exhibiting releasability from a mold with a small addition amount of a mold release agent without using an external mold release agent, while being capable of exhibiting high adhesion to other members without requiring a special surface treatment such as sanding.

    摘要： The purpose of the present invention is to provide a thermal conductor achieving both excellent light weight and excellent rigidity and also having excellent heat dissipation property. In order to achieve the above object, the thermal conductor according to the present invention has the following configuration. That is, a thermal conductor in which a sheet-shaped thermal conductive material (II) having an in-plane thermal conductivity of 300 W/m·K or more is contained in a porous structure (I) configured of reinforcing fibers and a resin.
