Abstract

PURPOSE: To obtain the title material having improved reinforcing effect even at a small amount of glass fiber and a large amount of a filler, by supplying a synthetic resin compound and chopped strands to a roving one after the other, and by pressing with rolls.
CONSTITUTION: The glass fiber rovings 2 are continuously supplied to the running substrate 1 at a pitch of 5W7 cm, and the compound 3 of an unsaturated polyester resin, etc. is applied to the rovings 2 by the doctor knife 8. The chopped strands 4 of other roving 9 are scattered over the coating layer and covered with the covering material 13 while being pressed by the nip rolls 12. The covered substrate 1 is then pressed by the impregnating rolls 5 to form the sheet 14, and the covering material 13 is stripped and wound onto the roll 15. The sheet 14 is pressed by the mandrel 6 to impregnate the compound 3 into the chopped strands 4, etc. thoroughly. The substrate 1 is stripped and wound onto the roll 7 to roll and cure the sheet 14 on the mandrel 6
