Abstract

PURPOSE: To obtain the title composite tube of uniform strength and high quality, at high production rate and operating efficiency, by wrapping three layers under specific conditions, using a thickened plastic mortar prepared by adding an organic thickener as a middle layer.
CONSTITUTION: A plastic mortar strip, prepared by incorporating an unsaturated polyester resin with an organic thickener, a hardener, and a filler, as a middle layer wrapped around an unhardened inner layer, and the outer layer is wrapped around the mortar layer. The layers are then hardened. The middle layer has a moderate hardness even in an unhardened state, and will not bite into the middle layer when the outer layer is wrapped. A composite tube having a uniform outside diameter can be obtained at high productivity.
