    摘要: A triaxial textile fabric for use as a reinforcing textile fabric for a composite material wherein the modulus of elasticity is made isotropic and which can be readily deformed into a three-dimensional configuration without causing special changes in orientation angles and a process by which such a textile fabric can be easily produced. The fabric comprises a large number of oblique yarns extending in a radial direction from the center of the textile fabric, and a circumferential yarn woven spirally in a circumferential direction between the oblique yarns. Each adjacent ones of the oblique yarns are interlaced with each other and the circumferential yarn is woven between the thus interlaced oblique yarns such that such interlacing may appear between each adjacent coils of the spirally woven circumferential yarn. Such an interlacing step takes place after insertion of the circumferential yarn and before an upward and downward movement of the alternate oblique yarns.

    摘要: A method and an apparatus for continuous shaping of carbon-fiber-reinforced plastic tubes, wherein a carbon fiber prepreg in tape form impregnated with a thermosetting resin is laminated on and around a mandrel, then the laminated carbon fiber prepreg tape on the mandrel is preheated, and the thus preheated laminate is pulled in and through a hot die together with the mandrel so as to subject the carbon fiber prepreg to gelling, curing and shaping into a predetermined carbon-fiber-reinforced plastic tube, the pulling operations being continuously carried out by alternate motion of first and second grasping mechanism in such a manner that the pulling force is generated in the second grasping mechanism, while the first grasping mechanism still retains its pulling force, and finally the gellation of the laminate is completed at the first half part of the hot die.
