Re: [highefficiencyvehicles] Re: Body Replacement/ carbon? why????

High strength (470,000 PSI) carbon fibers are used as reinforcement in high
performance structural composites for aircraft applications, recreational and
industrial products. Carbon fiber filaments are finer than a human hair. These
filaments are bundled together to make a fiber of 3,000, 6,000 or 12,000
filaments which is called a "tow". The tow is sized with an epoxy compatible
material to improve the handling characteristics. It is then wound on a
cardboard core holding from 4 to 6 pounds of fiber. 1 Lb. spool.This size will
be available in the small units shown. The 3 K and 12 K sizes are offered in
full spools only. The 3 K tow is used primarily by weavers. The 12 K is
difficult to wet out but can be done by diligent brushing.
It appears that the 6K tow will prove most practical for homebuilding
applications.

at those prices I'd hate to see the final cost... you'd need what? 150-300 lbs
of it? 
I've used the woven cloth version of this... but my point is cost... if you
really want to build it as costly as possible... but I want something I
can afford... 
The vehicle I'm building now is aimed at just under $10K... hard to do with
exotic materials...

Yup, uniaxial tow is often called graphite tow eg

I'd like to know who says carbon fiber is really that much "better" then just fiberglass??? ok it is a little bit higher on the strength to weight... but is...

 graphite Greg? LOLMy point is it need not be anything more exotic then glass cloth and epoxy resin over extruded poly styrene... that's what I like to...

that should read: and as you implied,  with carbon , you have to do a lot of engineering  just to get close to taking advantage of ANY savings in weight...
