:: View topic - Temp of P-tex

How hot can P-tex get?

I've got pre-preg materials and an autoclave at my disposal. The pre-preg materials require a cook of ~250F for 1 hour in the autoclave. Will this damage the P-tex?

I'm not too sure how hot P-tex can get without becoming damaged. None of our presses are heated so we've never had to deal the issue.

I can only point you to these guys Durasurf. They should be able to help you out.

By the way, where did you get the pre-preg?

Thanks Kam, I'll drop them an email.

I work for a company that makes pre-preg carbon stuff. I had a good idea the other day for how I can tool up up a ski that will enable even an imbicile like me to laminate it. We'll see if it works. I'll keep you posted.

btw, so glad I found this site. It rocks, thanks so much.

For those who care, Durasurf has told me that 250F at 80psi for 1+hour will not harm their P-tex.

Interesting that this is a HUGE difference from the Nordic-racing-nerds who tell me that passing a 125F tuning iron too slowly over the base while waxing can "burn" your P-tex and affect performance. HA!

Let's 'clave some skis!

Carbo:

that's what i want to hear: real information. i hope this encourages others to post similar info so we can build a HUGE database for other builders. anyway, thanks for your efforts.

send us some photos of your skis when you get a chance. we'll be more than happy to post them on this site!

carbo id have to say that some of us XC guys can by a pain when waxing but the slow iron has to do more with hurting the basewax that u have built up

Got some more info from the nice people at Crown Plastics, if anyone cares, probably way more info than most home builders want but.....

Gotta give 'em credit for thorough customer support. Answered my needs well.

peace.

Carbo: thanks for posting the info! it's very useful to know.

i am new at ski building, and i was looking online for fiberglass. it seems as though they come in different ounces. for instance, there were 6, 10, and 38 ounces. which should i buy?

we've been using 22oz. triaxial fiberglass for all of our skis. so far it seems to work well.

Hi,

I'm in the process of writing a report on the development of new techniques for applying graphics to production windsurf boards, and I'm trying to find out how other industries apply the graphics to their board based products.

Could anyone tell me how the ski industry applied thier graphics to thier skis?

thanks
