... electromagnetic fiber spreading methods, uniform coatings and fiber tensile strengths in excess of 2 GPa (290 ksi) have been achieved. This process has the potential to produce fiber tows much more inexpensively than current processes ( Ref 23 ). The SiC fiber obtained via CVD is thick and not very flexible...

In tensile testing, the polymers exhibit a well-defined yield point, followed by substantial cold draw, as shown in Fig. 1 . Unlike polyethylene, the stress increases during the cold draw, and consequently the...

..., and shear tests. It was found that the test specimens were sensitive to cut edges. As shown in Table 2 , the tensile strength of a graphite-epoxy (T300/5208) composite was reduced by approximately 60%. When longitudinal yarns (0°) were added, the strength reduction was less than 50%. Accordingly...
