Abstract

The characteristics of the off-axis strength reliability of notched UD composites is discussed. Tensile tests are carried out on polished specimens with various shaped notches introduced by a drill and a saw. The notches are observed with plastic replica and photographs to consider the effect of the machined damage. Moreover, each elastic field of specimens is analyzed with the Body Force Method to discuss the fracture process. The two parameter criterion proposed by Hashin is adopted as the fracture criterion, and the evaluation method for the strength reliability is proposed. It is found from the present data and the present evaluation method that the notch effect and the thickness effect can be expressed with the statistic factor.
