摘要： Disclosed are a laminate having a laminated structure of five or more layers wherein each layer is a resin impregnated fiber reinforced composition layer in which fibers are oriented unidirectionally, the resin in the resin impregnated fiber reinforced composition layer is an olefin-based polymer having the melting point or the glass-transition temperature of 50 to 300°C, and the shape of the laminate can be easily controlled by melt press molding; and a tape winding pipe excellent in balance between bending rigidity and compressive rigidity.
