<p>A process for the production of fiber-reinforced plastic (FRP) tubing, characterized by putting in a membrane bag a fiber-reinforced plastic intermediate material obtained by laminating two or more fiber-reinforced plastic prepregs, sealing the bag off, vacuumizing the inside of the bag, taking the resulting intermediate material out of the bag, and winding the material on a metal core to form the material: and FRP tubing which has a length of 750 to 1500 mm and a torsional strength of 1800Nm or above and bears plural fiber-reinforced plastic prepreg layers.</p> |
