INTERLAYER REINFORCED FIBER PREFORM AND PRODUCTION METHOD THEREFOR, STRUCTURAL MEMBER FOR ELEVATOR AND PRODUCTION METHOD THEREFOR, AND FIBER-REINFORCED PLASTIC AND PRODUCTION METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To obtain: a preform having high interlayer shearing strength; a structural member for elevator formed using an interlayer reinforced fiber preform; a fiber reinforced plastic formed using the interlayer reinforced preform; a production method for interlayer reinforced fiber preform; a method for producing the structural member for elevator including the production method for the preform; and a method for producing the fiber reinforced plastic including the production method for the preform.;SOLUTION: A production method for an interlayer fiber reinforced preform includes inclining the portion of a suture thread 14 positioning between the fiber textile layers 1 to 4 with respect to the lamination direction of the preform in the preform prepared by overlapping plural fiber textile layers 1 to 4 formed by a reinforced fiber to suture using the suture thread 14.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
