some of you have probably seen me floating about the forum, asking silly noob questions so heres another one for you.
i recently found a page that compared strength of carbon and kevlar
as far as i can remember it was on two planes, rigidity and flex. or something to that effect anyhow. i cant find the page but it stated that kevlar was about 20percent less rigid but much much better when it came to breaking points and flex.
so, after reading this and thinking about it for a while, taking costs into account i thought of removing carbon from the equation and going for a combination of kevlar and fibreglass. looking into it a bit more i came across this page which goes into much more detail than the first i came across
http://www.performance-composites.com/carbonfibre/mechanicalproperties_2.asp
so my question here is how much of these details are really relevant? i was going to look each one up but thought id ask here first.
i know that with the use of kevlar, woven fibreglass and a good core material like soric sf2 i can make a product better than many aftermarket cf panels. is my thinking wrong here? Bear in mind there are some atrociously poor quality carbon panels out there
oh, the application is car panels by the way, bonnets, bumpers etc...
thanks guys
