This method for producing a fiber-reinforced composite material includes: a fiber dispersion process of providing a fiber-dispersed resin by kneading a resinwith fibersto disperse the fibersin the resin; and a molecular weight reduction process in which, while transporting the fiber-dispersed resin along an outer peripheral surface of a screw bodyprovided with a passageinside, the fiber-dispersed resin passes from an inletof the passageto an outletof the passageand a shear force is applied to the fiber-dispersed resin by restricting the transport of the fiber-dispersed resin with a barrier unitdisposed between the inletand the outletof the passageon the outer peripheral surface.

Method for producing fiber-reinforced composite material

A production method for a low molecular weight polymer suitable for a melt-blown non-woven fabric and a production device for melt-blown non-woven fabric, with which a high molecular weight polymer can be reduced in molecular weight by applying a shear force to the high molecular weight polymer without adding an additive. The low molecular weight polymer and the melt-blown non-woven fabric are produced using a continuous high shearing device that applies a shear force to the high molecular weight polymer serving as a raw material by rotation of a screw body to reduce the molecular weight of the high molecular weight polymer so as to obtain a low molecular weight polymer, and cools the low molecular weight polymer by passing the low molecular weight polymer through a passage arranged in the axial direction inside the screw body.

Production method for low molecular weight polymer, and production device and production method for melt-blown non-woven fabric

In a production method for a conductive composite material for an extruder that continuously discharges a kneaded product produced by kneading a raw material using a screw, the screw has a the screw body, the raw material transported along an outer circumferential surface of the screw body receives increased pressure by a barrier part in a transport part and is introduced to a passage from an inlet, and while the kneaded product is continuously discharged, the raw material transported along the outer circumferential surface of the screw body flows in the passage of the extruder and then is guided to the transport part via an outlet provided in the screw body, the raw material contains a conductive filler and a thermoplastic elastomer.
