Short beam shear tests of graphite fiber composites

摘要: Abstract Short beam shear curves of unidirectional epoxy matrix composites with various commercially available graphite fibers are compared (Fig. 5(a), Table 1 ). Fiber-matrix adhesion and temperature varied. It is shown that the initial linear deformation due largely to spurious mechanisms other than whereas non-linear (or yield) entirely shear. Universally, yield sharp or broad for high low strength materials, respectively. Strength materials theory reasonably well predicts tensile failure mode transition L/d > 4. also accounts dependence apparent on failures. This be strong failures 9(a)) and, in this case, considered anomalous. Test apparatus some unique engineering features described.
