Based on effective composite material failure criteria and property limited degradation model, axial compressive ultimate strength of composite laminated stiffened panels are analyzed by nonlinear laminated degenerated 3D finite element analysis, which is based on incremental continuum-based updated Lagrangian formulation. Comparison between analytical solutions and test results in this article indicates that this article provides an effective and practical method to evaluate the axial compressive ultimate strength of composite laminated stiffened panels. Using this method, ultimate strength of hull girders made of continuous basalt fiber composite materials are analyzed . Comparing the results，it can be seen that the ship hull in basalt fiber composite materials has equivalent longitudinal ultimate strength to S-2 glass fiber composite materials, basalt fiber composite material could replace the S-2 glass fiber composite materials used in shipbuilding engineering. The gist for building ship with basalt fiber composite materials was provided by this paper.

Sufficient Strength

Wood-glass-fiber composite materials (WGFCM) are used in transport construction (sleepers, switch bars, etc.). Polymer solutions based on furfuralacetone monomer (FAM) served as a matrix for the manufacture of WGFCM. The article suggests using Holex HAS- 2061 polyester resin as a matrix, which, in turn, has chemical resistance, dielectric properties, increased impact strength, having sufficient strength characteristics, and significant extensibility. For the application of the above material in the structural elements of sleepers of logging railways, it is necessary to know its operation under repeated loading. Endurance experiments were conducted at different coefficients of the load application cycle asymmetry pb=0,1; 0,3; 0,6. As a result of the experiments, the values of the endurance limit of the material under study were obtained, which allow us to conclude that it can be used in the construction of timber railway sleepers.
