Unidirectional composites (UD) Simulation-Based Design

FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization

Unidirectional composites (UD) offer a large playground to tune optimal material properties. Thermoset and thermoplastic matrices are reinforced with different types of fibers: glass, carbon, aramid, etc. UD fibers are straight and non-crimped. In the laminate, they are laid up in specific stacking sequences, varying the fiber volume fraction, the thickness and orientation of plies. This results in the highest possible in-plane laminate properties in the final composite component construction. It is the general design principle for UD composites to use material properties in an optimal way. FEA Based virtual design and optimization of UD composites plays an increasingly important role in time and cost efficient development strategies.
