Someboby has asked me to make a carbon muffler. Has anybody had experience of this and could recommend a resin, preferably an epoxy, not phenolic?
Try search on here as it has been discussed and you will need a high temp epoxy resin. Try BJB Ent. in my section for suppliers.
The highest temps Ive seen are near 400 degrees…not all the time but it does get that hot on occasion…So Id say high temp epoxy.
I think the harder part (what Ive tried to figure out for cost effectiveness) is the core and ends.
Alot of them are rolled perforated cores…tack welded.
Then you have the endcaps and the tips…so that part of the fab can suck…I was going to pay to have a set of matching dies made for myself but its kind of spendy and I could only PRESS them one at a time…then to go and finish it with chrome is another cost…
Man the costs add up…its cheaper to just buy some carbon tubing already made to spec or a muffler made already.
If you look carefully you should be able to find a supplier of ready made carbon tube, of the sort required to make exhausts.
You can fabricate stainless steel end caps pretty easily, and use perf MS core with glass pack wadding to cut the noise.
Thank you for the link!
