When you really think about it, tree limbs and bones don’t break as often as you might expect them to. Natural composite materials such as wood and bone are low in weight and density, yet are strong and sturdy. This is often due to complex and diverse arrangements of fibers within a system. While humans have fabricated increasingly complex composite materials throughout history, achieving the same kind of intricate microstructures and mechanical benefits as those found in nature is a challenge.

Researchers at Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS, Cambridge, MA, US) have come up with a new 3D printing method inspired by natural composites. The idea was to achieve the best arrangement of short fibers at each location of the part being printed.

I’ve reported on carbon fiber use in the marine industry for over a decade now. It’s one of those trends that is always “imminent”. However, when you look at new product announcements over the past few years, a trend does seem to be emerging.

All of these production boats use carbon fiber and resin infusion. The Scout and Hinckley models also use epoxy resin. Carbon fiber has made its way into production boats in the past, for example in Baja’s 30-ft Outlaw. But then the recession hit, and the marine market dropped by 80%.
