Abstract

The article discusses the practical aspects of using the bootstrap method in micromechanics problems to assess the adhesive strength of the fiber–polymer matrix system. The article provides a detailed algorithm for constructing confidence intervals when calculating the bootstrap method. А comparative analysis of the interval estimation of experimental adhesive strength data using the nonparametric (bootstrap) method and a number of parametric methods was carried out. Based on the generated bootstrap samples, a histogram of the frequency distributions of the average values of the adhesive strength of the fiber–polymer matrix system is constructed.
