Considerations in Low-Temperature Mechanical Behavior of Polymer Composite Materials

Abstract:

In this paper it has been sought to highlight the mechanical behavior of composite structures at low temperatures compared to mechanical behavior at room temperature. For researches an experimental program has been conceived and built using factorial method. In this method, as dependent variable was taken the tensile strength (σ_r), while as independent variables were taken: the fiber orientation angles (θ), the degree of reinforcement (M_f) of the composite structure and the temperature (t) at which the tests were carried out (+25°C,-25°C and-50°C respectively). It has been used a complex experimental installation, specific to tests at low temperatures.
