The influence of process parameters (particularly the final heat treatment temperature) as well as test temperature up to 1800{degrees}C on the mechanical properties of two types of unidirectional phenolic resin based carbon/carbon (UD C/C) were investigated. The room temperature tensile strength of HT and HM-fibre reinforced carbon dropped to a minimum value after a carbonization temperature of 920{degrees}C and a following heat treatment at 1000{degrees}C. Higher heat treatment temperatures up to 2100{degrees}C led to improved tensile strengths. In contradiction to the heat treatment temperature the test temperature (RT to 1800{degrees}C) was found to have little influence on the strength.
