The Influence of Sample Preparation on the Strength Results ofa Pan-based Carbon Fiber


Fabio Pereira, Fabiana Vieira, Luiz de Castro and Ricardo Michel

In this work the influence of different configurations in the sample preparation process on commercial polyacrylonitrile-based carbon fibers mechanical tests were studied. Mechanical properties, such as tensile strength, Young’s modulus, elongation and Weibull modulus, were evaluated. The results showed that all sample preparation steps may have strong influence on the results.
