Process for production of fiber-reinforced plastic tubing |
摘要 |
The present invention relates to a process for a production of fiber-reinforced plastic tubing on a cored bar. Therefore, according to the invention, a fiber-reinforced plastic intermediate material obtained by laminating plural fiber-reinforced plastic intermediate material layers one after another is put and sealed in a bag-like membrane material, an inside of the membrane material is depressurized and then the fiber-reinforced intermediate material is taken out of the bag-like membrane material and wound around the cored bar to mold the FRP tubing.
