説明
This study evaluates carbon fiber/epoxy resin interface shear strength by a single fiber pull-out test considering an effect of resin meniscus existing at a near the root of embedded fiber. Conventionally, large number of works has been done to evaluate the interfacial shear strength by the similar single fiber specimen. They assume the near root of embedded fiber is perpendicular in shape and calculate the interface shear stress at interfacial debonding occurs. In other words, they ignore the resin meniscus dominated by wettability between fiber and matrix. In fact, the near root of embedded fiber is not perpendicular in shape so that the stress concentration would be significantly mitigated by the meniscus. The assumption may mislead consequently the interface shear strength. The effect of the meniscus on the interfacial shear stress distribution is taken into account. The actual interfacial shear stress which is independent of meniscus size and fiber embedded length is obtained by comparisons of analytical results with experimental results. The characteristic of the single-fiber pull-out test and validity of the obtained shear strength are discussed.
