One of the greatest strengths of composites is their ability to be combined and used in an infinite number of ways. From race car monocoques, to space shuttle heat sheilds, to bottle openers.
The ability to tailor the composition of a material to obtain desired overall properties is a very appealing prospect. Engineers are able to create you own materials to fit your specific need! However, with the advent of these novel materials, engineers are also inventing new ways for those materials to behave and fail. As a result, these engineers will need new ways to predict that behavior, beyond the traditional means used to analyze century-old isotropic materials.
One can at times feel like Leonardo DaVinci, creating a form-fits-function masterpiece - and at other times like Dr. Frankenstein, creating an unpredictable monster. It is a double-edged sword, and a topic that has been discussed and researched for several decades.
