Book excerpt: Accurate and efficient fiber characterization is critical to developing a successful process for producing low cost, high quality carbon fibers from pitch. This study analyzes current methods for characterizing diameter, tensile strength, and tensile modulus for carbon fibers using a Dia-stron® automated system consisting of a FDAS 765 laser scan micrometer and a LEX 810 linear extensometer. Fiber diameters measured by the Dia-stron® system are compared with diameters measured by Scanning electron microscope (SEM) and by optical microscope at 20X and 40X magnifications. Tensile measurements were also analyzed. This study found that fiber alignment during tensile testing is critical to determining a fiber's strength accurately. Most of the uncertainty in determining tensile strength, which is reported in terms of stress, comes from error in diameter measurements. The Dia-stron® had an estimated uncertainty of about 3.7 % for single measurements of a 9.8-micron diameter fiber. The optical method had an estimated uncertainty of about 9.6% for an 8.58-micron diameter. The SEM micrometer had a resolution of " 1 micron which for a 9.8-micron fiber is an uncertainty of about 10.2%. The range of uncertainty for the SEM method for fibers with diameters between 7 -- 12 microns is about 14.3-8.3%. The SEM and Dia-stron® agreed within 7% for a sample group. Individual fiber comparisons between the Dia-stron® system and the optical microscope had agreement between 2% and 15%. The SEM and optical methods both produced images of the fiber, but could only provide one view of the fiber due to its fixed mounting whereas the Dia-stron® system measured 180 degrees around the fiber circumference. The Dia-stron® was found to be the most efficient of these methods for taking a large number of measurements in a relatively short amount of time.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study is to investigate the relationship among process, structure, and property of the UTSI pitch-based carbon fibers and optimize carbon fiber's mechanical properties through the stabilization process. Various analysis techniques were employed throughout these investigations which include the Scanning Electron Microscope (SEM), optical microscope, Dia-stron system, MTS, and ImageJ. Several fiber process techniques including fiber spinning, stabilization, and carbonization were explored to determine the effect of the thermal process on the fiber yield, fiber diameter, the sheath-core structure of stabilized fibers, the pac-man and hollow core structures of carbonized fibers, and the resulting mechanical properties of the carbon fibers. It was found that stabilization time and the temperature stepping had a great deal on influence on the resulting carbon fibers. Larger diameter fiber is easy to form sheath-core structure in the stabilization process. Pac-man structure was developed at 600°C during the carbonization. Both stabilization duration and the carbonization temperature control the resulting carbon fiber diameter and fiber structure defects such as the pac-man and hollow core defects. Multi-step stabilization can reduce the total stabilization duration and improve the mechanical properties of the resulting carbon fibers. Fiber structure non-uniformities including fiber diameter distributions for a bundle fiber or along a single fiber, and pac-man angles were determined. Statistical analysis revealed the distribution of the carbon fiber cross-sectional areas and the result is compared against commercial available carbon fibers. Carbon fiber sandwiched composites (CFSCs) were fabricated with UTSI carbon fiber and commercial PAN-based carbon fibers. Several configurations of sandwich structured composites were explored to test the flexural properties with varying sandwich thickness.
