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.
Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. The rest of these new products are for a wide variety of applications including aviation, aerospace, electrical motors, electronics, industrial, and semiconductors.
A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
New sensor technology integrates sensors, traces, and electronics into a smart fabric for wearables that measures more dimensions -- force, location, size, twist, bend, stretch, and motion -- and displays data in 3D maps.
