Abstract
A tubular product is made of a fiber composite material and is composed of an inner layer and an outer layer. The inner layer is formed of a fiber tow by the filament winding method, whereas the outer layer is formed of one or more fiber sheets by the sheet rolling method. By virtue of the inner layer, the tubular product has a uniform rigidity. The outer layer serves to reinforce the flexural strength of the tubular product.
Claims7
A tubular product of a fiber composite material, said tubular product comprising an inner layer and an outer layer encircling said inner layer, said inner layer being formed of a fiber tow by a filament winding method, said outer layer being formed of one or more fiber sheets by a sheet rolling method wherein an orientation of all fibers of at least one of said fiber sheets are parallel with a longitudinal axis of said inner layer.
