The mantis shrimp's club-like arms have a unique structure that makes them extremely strong, tough, and lightweight, which could be adapted to make better body armor for soldiers. (Source: Silke Baron)
Wiliiam, thanks for the feedback. The oriented chitin fibers on the outside of the club also caught my attention, as did the organized and rotated layers of chitin fibers. That sounds like basic fiber-composites structure. In fact, it made me wonder if, historically, our modern fiber composites were inspired by nature in the first place. Anybody know the answer?
There's a link in the first sentence of my article to the Science article describing this structure in as much detail as the authors are willing to divulge. As is typical of some university R&D efforts aimed at commercial development, though, it may not give all the info that some readers would like. (Dave, thanks for the additional link)
This has been done for decades on tanks, etc, various layers of different materials to break up the impact, thermal energy. I use the same idea in my composite EV designs for crash protection.
Again lack of actual details of the structures hurts this engineering article that one might use. Pic's could help to of a cross section, etc.
If not the right shape it wouldn't get the speed needed as water drag would be too high.
Shimpers fear this creature as it splits a finger in a heartbeat if they pick one up or get close to it sorting market shrimp from the bycatch.
Sadly this style of shrimping, fishing dragging nets across the bottom is killing our fisheries and should be banned because it destroys the habitat, young fish, coral, plants, etc that sealife needs to live and we need to eat.
Wow, this is neat. I'm also impressed by the teardrop shape of the shrimp club --- I'm assuming that the high velocity achieved though water is the result of some nifty fluid dynamics and complex vortex shedding... Oriented fiber- and hybrid composites continue to behave magically, based on the systematic perspective that the whole is greater than the sum of its parts. Now I'm just waiting for grant money to investigate the turkey club -- it's almost lunch time.
Dow Chemical and several other companies have launched a program in Omaha, Neb. to divert about 36 tons of plastics from landfills in its first phase, and convert it into energy used for cement production.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
Some next-generation bio-based materials are superior in performance to their petro-based counterparts, but also face some commercial challenges. This is especially true of certain biopolymers, adhesives, coatings, and advanced materials.
Cars and other vehicles, as well as electronics and medical devices, continue to lead the use cases for the new plastics products we've been seeing, as engineers design products for tougher environments.
