In short fiber composites, energy absorption mechanisms, such as interfacial debonding and matrix cracking, most often occur at the fiber ends (Curtis et al., 1978). The damage model proposed by Bader et al. (1979) assumes that short fiber composites fail over a critical cross-section which has been weakened by the accumulation of cracks, since the short fibers bridging this critical zone are unable to carry the load. In fatigue loading, sudden fracture takes place as a direct result from the far-field effect of the composite, rather than due to the near field of the crack tip...

Fig. 10.10 Curves showing the time needed for crack extension by matrix creep as a function of crack length for various values of the interface viscosity, /. Also shown in the figure is the case wherein fiber bridging is absent. See text for discussion.

Shearography shearography is used for impact damage, wrinkles, delamination, and fiber bridging. 

Fiber bridging Reinforcing fiber that bridges an inside radius that is caused by shrinkage stresses around such a radius during curing. 

The observed improvement may be ascribed to the attraction of neutral or positively charged polymer complexes sphere to the negative charges known to exist on the fibers, i.e., cellulose fibers bridged through CMC-Cu(II] complex. Also, the presence of...
