    摘要: Provided is a high-quality and high-functionality glass chopped strand mat which is applicable to recent automotive molded ceiling materials which have excellent design and reduced weights. The glass chopped strand mat is a glass chopped strand mat (M) produced by forming glass chopped strands (S) into a sheet, in which the ratio of a tensile strength in a width direction to a tensile strength in a longitudinal direction (the width direction/the longitudinal direction) of the glass chopped strand mat (M) is at least 0.73 and less than 1.00, and the tensile strength in the width direction is not less than 80 N as measured in a tensile rupture test conducted according to the Japanese Industrial Standards (Section 7.25 of JIS R3420 (2006)), where the width of a test specimen is 150 mm.
