Document Type and Number:
Japanese Patent JP2018203464
Kind Code:
A
Abstract:
To provide a method of manufacturing a wound body of a glass chopped strand mat, and a wound body of a glass chopped strand mat, capable of suppressing an occurrence of winding deviation and wrinkle during its manufacture.SOLUTION: The method for manufacturing a wound body of a glass chopped strand mat M including a glass chopped strand S, includes a step of winding the glass chopped strand mat M in a roll shape to form a wound body by bringing a tip end portion M1 of the glass chopped strand mat M into contact with the outer peripheral surface of a winding core 72 and rotating the winding core 72, in which a coefficient of kinetic friction measured on the outer peripheral surface of the glass chopped strand mat M and the winding core 72 in accordance with the method defined in JIS K 7125 (1999) is 0.25 to 0.35 and basis weight of the glass chopped strand mat M is 70 g/mor more and 250 g/mor less.SELECTED DRAWING: Figure 1
