- At this point the starting process occurs at low engine loading conditions. At these operating points the engine emissions will primarily take the form of HC and CO emissions. Direct measurement of starting emissions is made difficult by unburnt and partially burnt fuel contaminating gas sampling hardware. After ignition at particularly low engine loading, as would be the case during engine starting, emissions of HC dominate.
- As long, thin members, the fibers are designed to carry tensile loads. However, in the common case of composites with ply-wise variations in fiber orientation, tension loads do not run parallel to the fibers, and failure can occur in the matrix. Common matrix failures associated with such loading conditions are tension failures between fibers, particularly at the fiber-matrix interface, and shear failures in the matrix-rich region between plies, typically associated with rough features on the fracture surface called hackles. Such inter-ply shear failures can also be produced under compression.
