... either by the fracture of fibers or by the fibers pulling out of the matrix. Both possibilities are shown in Fig. 10.4 . Pullout will occur if the plane of the crack is near the end of the fiber. If it is not near the end, the fiber will fracture. Figure 10.5 is a picture showing the pullout...

... to delaminations, cracking, fiber pull-out, fiber fuzzing (aramid fibers), matrix chipping, and heat damage. It is therefore important to minimize forces and heat generation during machining. During metallic machining, the chips help to remove much of the heat generated during the cutting operation. Because...

..., fiber bridging, and fiber pull-out. A notional stress-strain curve for a monolithic ceramic and a ceramic-matrix composite is shown in Fig. 11.2 . Because the area under the stress-strain curve is often considered as an indication of toughness, the large increase in toughness for the ceramic-matrix...

High load results in more fiber cracking and pulverization, leading to deterioration in load-carrying capacity, while high speed accelerates the debonding of fibers/fillers. This results in easy peeling off or pulling out of the reinforcing phase...

.... If the unstaged prepreg mount is held in one position for even a short period of time, some of the fibers may be pulled out and the surface smeared. It is also essential that a large quantity of water is used on the wheel for cooling. Water is the best coolant, because the majority of the resin matrices...
