摘要：
In the present work the influence of various carbon fiber types including heat treated fibers on properties of pitch-based carbon-carbon composites reinforced with these fibers was studied. Carbon fibers from different manufacturers were heat treated at 2400 degrees C and 2800 degrees C. Their physical and chemical properties were studied and compared with original fibers. Physical and chemical properties of carbon-carbon composites reinforced with obtained fibers were analyzed. It was found out that fiber hardness leads to improvement of their mechanical properties. The cross-sectional shape of the fibers and the thickness of the fiber tow lead to different orientation of the fibers in the composite which significantly affects composite properties.
