Abstract: PURPOSE:To enable revolution at superhigh speed of a centrifuge by arranging a base material of a rotor comprising a composite material consisting of resin or metal reinforced with fiber arranged laminary and in the direction of rotational axis, and constructing the rotor pseudoisotropic in a plane intersecting perpendicularly the rotational axis. CONSTITUTION:Insertion holes 4 for centrifugal separation tubes are bored in a solid rotor 2 equally distributed around the axial center X and with a same distance from the axial center X, wherein the rotor 2 is formed of a composite material consisting of resin or metal reinforced with fiber. The reinforcing fiber material comprises a fabric material consisting of unidirectional base material and/or reinforcing fiber prepd. by aligning the reinforcing fiber parallelly in one direction to form sheet. Above-described base material is arranged laminary in the direction of the central axis X and the rotor 2 is constructed pseudoisotropically in a plane intersecting perpendicularly the central axis X. As a result, not only a revolution at superhigh speed is possible with small energy consumption but also the time required for acceleration and deceleration are short, and a rotor for centrifuge of high analytical efficiency is provided.

Abstract: PURPOSE:To manufacture the title laminate having improved strength and flexural rigidity, by laminating continuous fibrous materials impregnated with an uncured resin on a rotating drum under tension, and by cutting the cured material. CONSTITUTION:A plurality of prepreg sheets 1 fed by the guide rolls 3 under tension are heated by the preheater 4 at about 50-150 deg.C, fed to the rotating drum 5, and laminated by the roll 7 while removing the air between the sheets 1 in the vacuum chamber 8. The laminated sheet 1' is then pressed by the rolls 9 under a pressure of about 1-5 kg/cm heated by the main heater 10 at about 100-200 deg.C, shaped and cured into a curved form of desired thickness along the surface of the rotary cutters 11 (longitudinal and lateral cutters 11L and 11T) on the drum 5 in the longitudinal and lateral directions to give the desired fiber-reinforced resin laminate 1'''.
