<p><P>PROBLEM TO BE SOLVED: To easily manufacture a tubular body having lightweight properties and high rigidity with good moldability. <P>SOLUTION: The tubular body is manufactured by a process for laminating fiber-reinforced resin layers each of which comprises reinforcing fibers and a thermosetting resin to form a tubular preform, a rotation control process for rotating the preform while heating the same to a temperature below the curring temperature of the thermosetting resin to allow the resin in the preform to flow to the outside in the diametric direction of the preform by centrifugal force not only to fill the gap, which is not filled with the resin in the preform, with the resin but also to control the resin content on the outer surface side so as to increase the same, a curing process for heating the preform controlled in resin content to the curing temperature of the thermosetting resin during or after rotation to cure the same to obtain the tubular body and a grinding process for grinding the outer surface increased in resin content of the tubular body. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
