Abstract
The dynamic mechanical analysis (DMA) method was utilized to investigate the dynamic mechanical properties of the carbon-phenolic composite, and of carbon-carbon (C/C) composites carbonized at 1000°C, and graphitized at 2200°C. The measurements were performed in the temperature range 50–450°C. Results show that the carbon-phenolic composite has the highest storage modulus, while the carbonized C/C composites possess higher storage modulus than the graphitized C/C composite. The storage moduli of carbonized and graphitized C/C composite do not change significantly in the test temperature range. The tan δ, loss factor, of carbonized C/C composites increases 59.5% during the tests from 50 to 450°C, and that of the graphitized C/C decreases 9.74% in the same temperature range; graphitized C/C shows the highest tan δ at 50 °C. The carbon-phenolic composite shows a damping peak at 250 °C, which is probably due to the transition from glassy state to rubbery state of the phenolic matrix. The higher tan δ of the graphitized C/C composite may be due to matrix graphitization, fibre-matrix debonding and crack formation, which were observed on the micrographs.
