A new carbon helical spring for use in high temperature and/or corrosive atmosphere has been developed by using carbon/carbon composite. The characteristics of the carbon spring were dependent on the property of the composite, diameter and pitch of the coil and its turning number and obeyed Hooke's Law within a certain limit of the load. Lateral elastic coefficients of compression springs were 1.7_??_2.8×106 gf/mm2 and those of tension springs were 1.0_??_1.710×106 gf/mm2. They were found to posess a sensitivity responding to the slightest stress.Permanent set in fatigue of the carbon spring was not observed.
