Now for some real bigboy composite action..

[#Rotor]

oh yeah!!! no more whimpy half-assed stockings and polyester-resin excuses for trying to be the real thing...... this is the real thing.... :D

real Carbon Fiber and some damn expensive epoxy resin to go with it....
I need to point that this is in-fact, my very first hand at using epoxy resins, they are somewhat different than the polyesters and I am not to disappointed at this first try.... though there is much room for improvement, mainly in the mold-making part of the effort, as I had so much trouble in getting the damn thing to separate, the mold got damaged..... NOT GOOD.. :(

aaa well,, the 2nd try is already curing.... hopefully this time it will go better...

hope you've not got woven roving on woven roving ?
interlaminar shear strength drops way down

[#Rotor]

Is why I will stay away from making suspension components and wheel-rims for a little bit, till I get a little more glued up in this...... I will stick to decorative items, mud-flaps and fearings for now.... :)

Some more pic's

ps: I don't quite understand what you mean by what you said.... care to enlighten me...
:cool:

cf is nice, I was in the pipe business so only used glass
same composite design issue though

MMMM, CF looks purdy. Are those new high heel soles for your lady friend? :D

Nice pedals, though.

ha! the only LADY in my life, is getting herself a CF dash, in the not too distant future.... those pics in the other thread is of the prototype..... once it is 100% perfect, I'm going to pull a mold of it too, and then to copy it in CF..... is the reason why I now am getting myself familiar with the intricacies of working with this shit... and doing so on small stuff(this is very very expensive shit).... like my brothers YZF-R6's bootgards. will snap some pictures of this first one, on the bike tomorrow. As I said, very expensive stuff, screwing up on a big thing.... well that just ain't an option....

missed this, sorry

the more fibers are 'worked' the more they degrade, woven roving (bi-directional) is used to get high fiber loadings which yields better tensile strength in those 2 directions
as the structure bends each layer tries to move relative to those adjacent resulting in a shear stress
woven roving to woven roving has very poor shear stress capability
this can be remedied somewhat by placing a layer of mat (randomly oriented fibers) between the layers of woven roving

a simplified description

oh, they are for a motorcycle. I thought it was a go-fast pedal for your car.

the 2nd mold is made and number two is allready in....

Update time...... :drool:

my 2nd try yielded approximately a 437.03% improvement. :D
I am happy now :)

[killernoodle]

Looks very nice.

[nicozeg]

Once you are used, epoxy is a lot better than polyester. i'm so used to it, that it don't seems expensive to me given all the advantages :D

[#Rotor]

I can agree with that.... much nicer stuff to work with indeed.....

here is some shots of it on the bike itself.......

Now just for some perspective.... a set like this, here in South Africa, R1200.00 give or take..... that's about $200US :mad: :D :D :D

[#Rotor]

here it is with some clear coat, makes it look real 3D, allmost :D

Yeah, we do the same thing fiber glasing sail boats. A layer of bi-directional weave fibers, then a layer of omidirectional fibers, then another layer bi-directional weave fibers.

CF looks nice though.

[nicozeg]

Nice looking parts. May I ask what is their use? I cant see what usefull thing they do in that bike. :p

[#Rotor]

it's called "heal-guards" or "boot-guards" they probably don't do much other than look nice, but theoretically they are there to keep your boot from going too close to the rear swing-arm...
