Abstract

The present invention provides: a fiber-reinforced resin sheet that exhibits a higher tensile strength; and a method for manufacturing said fiber-reinforced resin sheet. The fiber-reinforced resin sheet comprises: multiple reinforcing fibers that are arranged so as to be oriented in one direction; and a thermoplastic resin with which the reinforcing fibers are impregnated. A variation coefficient of the standard deviation of orientation angles of the multiple reinforcing fibers is 17.0% or less. The fiber-reinforced resin sheet is produced by a method that involves impregnating multiple reinforcing fibers arranged so as to be oriented in one direction with a thermoplastic resin, and, by using a cooling roller, cooling the fibers while applying pressure thereon, and that satisfies at least two of conditions (1)-(3). (1) The multiple reinforcing fibers are to be impregnated with the resin while being subjected to a tensile force of 800-2000 cN. (2) Cooling while applying pressure is to be performed by causing a cooling roller to apply a pressing pressure of 1.0-6.0 bar. (3) Cooling while applying pressure is to be performed by a cooling roller that has undergone a release treatment.

Abstract

The purpose of the present invention is to provide: a pellicle frame in which warpage caused by tension in a pellicle film is suppressed, and which can suppress warpage of an original plate cause by deformation of the pellicle frame; a pellicle; and a pellicle production method. A pellicle frame comprises: a hard frame member (12A) for supporting a pellicle film; and a soft frame member (11X) for connection to an original plate having a pattern. The soft frame member (11X) is connected to the hard frame member (12A). The soft frame member (11X) is obtained by alternately laminating base material layers (112) and adhesive layers (111) in the thickness direction orthogonal to the planar direction of the pellicle film, such that an adhesive layer (111) is disposed at each end. The Young's modulus of the hard frame member (12A) is higher than the apparent Young's modulus of the soft frame member (11X). The Young's modulus of the hard frame member (12A) is not less than 25 GPa.

Abstract

The present invention addresses the problem of providing a novel olefin resin useful as a compatibilizer for a polypropylene resin and a polyethylene resin, a method for manufacturing the olefin resin, and an application for the olefin resin. The olefin resin (β) includes a graft-type olefin polymer [R1] having: a main chain which is constituted from a propylene homopolymer or a copolymer of propylene and ethylene and in which the content of propylene-derived structural units is 76-100 mol%, and the content of ethylene-derived structural units is 0-24 mol%; and a side chain which is constituted from an ethylene homopolymer or a copolymer of ethylene and propylene and in which the content of ethylene-derived structural units is 80-100 mol%, and the content of propylene-derived structural units is 0-20 mol%.
