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.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
Healthcare might seem to be an unlikely target application for the Internet of Things technology, but recent developments show small ways that big-data is going to make an impact on patient care moving into the future.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
