This paper examines the possibility of introducing a composite material based on fiberglass and carbon fiber. A truss beam was taken as the model under study, in which all bracing elements were replaced with a composite. In total, the work considers three types of braces: braced, cross, and combined (a beam with a cantilever, where braced and cross ...
