	<htmltext>I still use a wooden stick.  Then again, the flexibility of the stick is a factor in how I play.  You can get a lot of power out of the spring return of a hockey stick with certain kinds of shots.  Of course, we didn't have composite sticks when I was a kid, so this is how I learned.
<br> <br>
Aluminum sticks were the new thing when I was growing up.  The advantage is that they rarely break (I think the blade is replaceable wood).  I broke a LOT of wooden sticks growing up.  Carbon fibre... never tried it.  They're probably great.  From what I understand, carbon gives the manufacturer a lot more control over the flexibility.</htmltext>

	<htmltext><p><div class="quote"><p>My only concern is how well the honeycomb material handles impacts (everything from birds to micrometeorites...).</p></div><p>
I don't know about birds, but in my space materials class we were told off the cuff that honeycomb materials (depending on the various base materials used) were actually very useful for micrometeorite impacts because the multi-layer nature of them tends to reduce the energy through the impact on the first and second layer (if there are more than 2) and trap the meteorite prior to entry into the spacecraft bus. Of course, certain blankets also perform a similar role, some better, some worse. It should be noted that most spacecraft actually have multiple layers of structure to them to protect their soft, squishy innards from everything from heat and radiation to micro-meteors and structural integrity collapse. In other words, NASA already knows to account for these things as you mentioned.
<br> <br>
However, in response to your honeycomb curiosity, from my understanding, it depends entirely upon what kind of honeycomb you use. After all, honeycomb structures can be made with everything from trampoline fabric to wood or aluminum....or both...or all three...yay composites!</p></div>

The skin of the B2 bomber (designed late 1980's) is fiber composite.
The main structural frame of the Hubble Space Telescope (designed/built in the early 1980's) is fibre composite.
Honeycomb composite control surfaces (ailerons, rudders, elevators) have been common in military aircraft since the 1970's, and in carbon fiber composites in civilian aircraft since the late 1980's.
  Heck, NASA built a major structural component of the Saturn V booster (the SLA [wikipedia.org]) out of honeycomb composite.When Carbon Fibre started to become omnipresent in road cycling it was only sparing used in mountain biking.
This was due to precieved, and real, issues dealing with durability.
Rocks and branches hitting Carbon Fibre frames and causing small failures that normal use would increase and cause catastropic failure.
But now carbon is everywhere because design and testing have overcome these problems, and the aerospace industry, with actual and good engineers will be able to do the same.Carbon fiber has been around in the aerospace industry for quite a while now.
I suspect the bucket loads of cash the aerospace industry has spent on R&amp;D on composite materials over the last fifty years has had a lot more impact than the comparative eye dropper loads of the bicycle industry.

	<htmltext>So what you are saying is that instead of investing in space technology so that we can see spin-offs in other areas, we could be investing in bike technology that spins-off to space technology.
<br> <br>
That's not how it's suppose to work. It's suppose to be only space that has spin-off technologies.<nobr> <wbr></nobr>/sarcasm
<br> <br>
We really need to realize that any tech that pushes the envelope will have spin-off technologies.</htmltext>
