The energy stored in a flywheel depends on the strength of the rotor material. Carbon fiber tensile strength remains well below theoretical limits. Expected increases in strength along with reduction in cost as the use of this material expands will translate into more energy dense, less expensive rotors.

Based on the same average fiber tensile strength model as that employed in Section 4.2.3, the fiber fragmentation criterion is derived in terms of the external stress, ffa(= (h = o er, for the partially debonded interface ...

The mean fiber fragment length, 2L, is plotted as a function of the applied strain, e, in Fig. 4.18. Similar to the results for the fully bonded interface model shown in Fig. 4.12, the full frictional interface model predicts that (2L) decreases sharply with increasing applied strain within a short range of c. A high fiber tensile strength...

The polymer was extruded at 240 C to produce 28-strand multifilament yarn. The yam was hot-stretched and fiber tensile strengths in the range 3-6 g/den (1-2 dpf) could be obtained. The yam was placed on braider bobbins on a 12-carrier machine with 7-ply core. The braid was made with 51 picks per inch and hot-stretched 25% at215 F.

A study about the effect of twelve factors of material preparation with regard to fiber tensile strength was done in the textile industry. Four researchers were asked about the prior ranking of the factors. The rank matrix obtained on the basis of a research poll is shown in Table 2.14. Check the concordance of researchers opinions and choose the significant factors for the next step of experimental research. 

The individual fiber properties which contribute to the tensile properties of paper include the following (8) fiber tensile strength mean fiber length fiber cross-sectional area perimeter of the average fiber cross section density of the fibrous material fraction of the fiber area bonded in the sheet and the shear strength per unit area of fiber-to-fiber bonds. 

Some fibers exhibit fracture mirrors when they fail within a composite (e.g., Nicalon). A semi-empirical calibration has been developed that relates the mirror radius, am, to the in situ fiber tensile strength, S, given by (Fig. 1.20),...
