composite structures

The filament winding method is one of the most efficient technologies for manufacturing composite structures with high strength-to-weight ratios. Traditionally, this process has been widely used for the production of axisymmetric structures such as pressure vessels, pipes, and cylindrical shells. However, modern aerospace and mechanical engineering increasingly require the production of composite structures with complex geometries, including prismatic and frame-type elements.

Structures carry various types of load during their exploitation. The effects of a longterm load component are significant mainly for the structures in which concrete fulfils its static function. Besides some instant effects; however, there are rheological properties of concrete that manifest themselves under applied forces. Creep, for instance, is time-dependent, and its effects can considerably influence deformation in composite steel and concrete structures.
