Crack propagation in composites and how to avoid it: A DLR case study
Ceramic matrix composites (CMCs) have become especially popular in space applications due to their ability to withstand extremely high temperatures. At the German Aerospace Center (DLR), researchers are investigating the use of CMC components for high-temperatures and demanding-environment applications.
How Rule of Mixtures is Killing Your Composite Design
Rule of Mixtures is probably the most known and widespread method of estimating composite properties. Its notoriety in composite design circles is also its main problem: Rule of Mixtures has been overused and applied to cases that do not even come close to respecting its original, simplifying assumptions.
Multiscale Analysis: A General Overview and Its Applications in Material Design
Modeling advanced materials accurately is extremely complex. Multiscale simulations achieve balance between simulation accuracy and computational efficiency by capturing their behavior and important features at multiple scales.
High Velocity Impact on Composites – Past, Present, and Future
In 1969, Grumman Aerospace was the first company to successfully introduce advanced composites into a commercial airplane. The boron-epoxy laminated horizontal stabilizer used in the F-14A was 15% lighter and 18% less costly than its metal counterpart.
