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)
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.
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.
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)
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?
Thanks. Yes that was the link. I'm used to "An article in Science recently....." being the link.
Was there anything about the mechanism to provide reactions for this rapid movement? When something is moving this fast and with this much power there has to be some way to provide support for the arms.
A tiny humanoid robot has safely piloted a small plane all the way from cold start to takeoff, landing and coming to a full stop on the plane's designated runway. Yes, it happened in a pilot training simulation -- but the research team isn't far away from doing it in the real world.
Some in the US have welcomed 3D printing for boosting local economies and bringing some offshored manufacturing back onshore. Meanwhile, China is wielding its power of numbers, and its very different relationships between government, education, and industry, to kickstart a homegrown industry.
