A fiber reinforced resin molded body; including: resin-integrated carbon fiber sheetsthat are stacked and unified, each of the resin-integrated carbon fiber sheetsincluding a carbon fiber sheetand at least one resinselected from the group consisting of thermoplastic resin and thermosetting resin. The carbon fiber sheetincludes a unidirectional long-fiber groupspread and arrayed in one direction, and multidirectional fibersandderived from the unidirectional long-fiber group. The multidirectional fibersandcross carbon fibers constituting the unidirectional long-fiber group. The fiber reinforced resin molded body is a molded body of two or more stacked layers of the resin-integrated carbon fiber sheets, or a molded body of the resin-integrated carbon fiber sheetthat is stacked with a resin-integrated carbon fiber sheet including a different carbon fiber sheet. Thus, the present invention provides a fiber reinforced resin molded body including a surface-modified carbon fiber sheet and thus having high interlaminar fracture toughness, and a method for producing the carbon fiber sheet for the fiber reinforced resin molded body.

Fiber-reinforced resin molded body and method for producing carbon fiber sheet used therefor

A toothed belt has therein a core wire () including a core thread () made of aramid fiber and a filament thread () made of nylon fiber, and has belt tooth portions () and belt groove portions () alternately formed therealong. The core wire (), the belt tooth portions (), and the belt groove portions () are integrated with one another by a rubber material (). It should be noted herein that the core thread () and the filament thread () are integrally twined around each other so that the filament thread () is formed in the shape of a plurality of loops around the core thread (). The filament thread () in the shape of the loops enters tooth root portions () of the belt tooth portions () to be arranged therein. As a result, the tooth root portions () are strengthened.

A centrifugal separator able to function as an agitator. A motor controlled by a control box drives a disk-like rotor. For agitation, the motor makes the rotor intermittently rotate, and for centrifuging, the motor makes the rotor constantly rotate. The rotor has a pair of pins which are extended in a tangential direction to the rotation of the rotor. A bucket for accommodating a sample container is freely swingably supported by a pair of pins. During the alternate repeat of the rotation and stopping of the rotor, the bucket with the sample container performs regular swing like a pendulum in the radial direction of the rotor. The rotation of the rotor and the swing of the sample container generate a smooth circular flow of the liquid content in the sample container.
