First off i am excited about your website and applaud you on your information that you supply. As I have read your sites and the information over and over again there are some things I would like to clarify and confirm, before actual execution in ordering supplies.


I would like to make a carbon fiber (CF) heat shield to replace the metal one that covers the exhaust can on the bike..

My question are:

1) Is it necessary to have a autoclave to cure the part...after making a mold and laying the proper amount of CF using the High heat kit  products? what other method can I use, vacumm bagging? if so it will take some time too save up to order the entire kit. I hope there is an alternative?

2) Can carbon strips be used with pre-preg epoxy/resin and CF overlay....or wet lay application? Do the strips have a friction capacity or wear factor?
Let me clarify, I am an avid motorcyclist and racer, Now that I have found you guy's I would like to build my own parts for my bike, because I don't like the design or quality of what's out there..although I won't be getting this part done right away, I would like to do my research and converse with you guy's to help in this development.

I am developing an idea and the strip layied between the cf layers, would allow the thickness and support of the part, to cut cost  and give me the confidence that the part would work. because this part may hit the ground in a crash I want it to not wear through, which is for the purpose of the part....should it work I believe it will revolutionize the market for me and fellow riders/racers......

Can the strip be shaped or is it rigid?
what would I use to get a clean cut if I were to cut the strip heavy duty and the other thickness's...a ban saw? what kind of blade.

I know it's allot to start off with, however that's what this site is for and yes I am going to start with a simpler mold/part to get an idea of how your system works. the reason for these questions and answer's are for the final decision in to buying the basic kit or buying the bulk products to build more than one product at a time. I am also aware of that there will be trial and error along the way.....this is why I am leaning more towards the bulk molding, resin etc.......trust me guy's this won't be the last conversation we will be having. I want to thank you in advance and please have patience..I have some fiber glass experience so I am not oblivious to the methods. Truly your products, methods and info. are far more superior than what's out there, or at the least, much more user friendly......


Now for the first project question?

It looks like I will need to buy the separate products (epoxy gel coat/resin) etc..  to build a "carbon Fiber" front fender for my bike due to it's size, correct? Are there any tips you can provide me with as well...

Understanding it's a rather large part vacum bagging would probably be ideal....however don't have 500.00 dollars right now but saving...I am also building my race bike so you know what that cost......

I hope I have posed my questions or began to paint a picture that is easy for you to visualize as to what I am attempting to achieve.

Thank you in advance,

Martin (Twissta...throttelman....!) say it fast and it will make sense LOL

Ok bro, gotta think this one through then, on the front fender....Might do the rear fender first, since it is smaller in size and probably would be easier for my first project. Read and re-read for (understanding) your response before I bombard you with more questions,


Thanks again,
