Thanks composite pro. From what you're saying, it seems maybe I should go the route I was thinking of going earlier and hook up my resin trap between the pump and bag, and use infusion matrix rather than bleeder felt and porous Teflon rather than perforated peel-ply, so that the resin gets...
I've been brushing epoxy into the mold before laying these parts (laid 3 now). The issue with that is that the epoxy does not adhere to the silicone mold at all, and actually puddles up, rather than spreading out. I really like using the silicone though, as demolding the part is ridiculously...
Thanks for the reply.
I can't let the lay up cure in open air, as without the vacuum, it will not completely conform to the mold. I haven't tried it, but have noticed that very thing happening during the lay up process.
As for holes in the tool, that is not possible. I'm using a two sides bag...
Guys, I have been fiddling around with composites for a while and I keep running into the same problems, despite changes in technique.
Let me explain what I'm doing right now. I'm laying 3 layers 6oz/yd^2 twill weave carbon fiber into a silicone mold that's about 6"x20" and 1/4" deep. It is a...
Thanks, composite geek. The plaster idea has crossed my mind (in fact, i remember reading about mixing plaster with baking soda so it could be dissolved with boiling water, rather than broken out). I can't really break out the plaster, because the pipe will be about 3" diameter and 3' long...
Hey guys, thanks for the replies. I do recall having read about water soluble cores before, but it slipped my mind for some reason. I think when I read about it, the person had used a combination of baking soda and some sort of water soluble putty sold as a powder that is widely available in...
That's an interesting method! Similar to the wax method I was toying with. I've used the wax method for parts before, but it really didn't seem practical for anything other than 1-off parts. I'll have to look into the salt. Is there a special variety I should be looking for?
thanks again.
Hey guys, I'm pretty new to this forum, but I did some searching for an answer to this to no avail.
Here's what I'm looking to do...I'd like to make some intake piping for automotive applications from biaxial carbon fiber sleeves. They'll probably be about 3" ID. Dimensions asside, how would I...
