Abstract Scope |
The additive manufacturing of continuous carbon-fiber reinforced composite is a simple way to obtain complex parts with good mechanical properties. However, it remains difficult to perform numerical simulations on such materials, as it is difficult to find the elastic coefficient of the whole material. Using a new model of periodic homogenization, which considers both the fiber rate and the porosity, would be a quick solution to predict the mechanical properties of the printed composite. Based on material studies and validated with mechanical tests, this simulation model allows the use of a homogeneous material to replace the composite material for the finite element analysis. This will strongly reduce the number of elements required in the model, leading to a decrease of the computation time. Hence, the numerical model will be more suitable to perform optimization processes. |
