If you use anyhing else besides fiberglass materials (mat, clother, etc), it is no longer fiberglass. Ther 'glass materials are made of real glass (same as house windows, etc) that are metled in thin strands and woven together. The glass is where the strength is.
If you subsitute glass with something else not made for strength, you will have a weak or unsafe part. The only other subsitute materials I'd use would be carbonfiber or Kevlar and other materials made SPECIFICALLY for composite manufacturing. If not all of the strength may only rely on the resin alone, which is brittle.

I am fully aware of reinforcements(fiberglass,cloth, mat,Kevlar,Carbon fiber)I am refering to something completely different.Check this sight for details: http://www.selectproducts.com/shopsite_ ... page1.html
Mold glass is stretched over a "Shape"(dash,or something simmilar) and resin is poured over it to produce the part.I was just wondering if there is anything "special" about this mold fabric or if its simply a polyester fleece material that is available at any fabric store.Kind of like instead of paying big money for vacuum bagging film,you can buy heavy visqueen plastic and it works just fine.Releases from epoxy and polyester resins with no problems.I like http://www.fiberlay.com/ and http://www.a-c-m.com/
Fiberlay is a little cheaper than fibreglast.[/url]

If you are just making a mold then you can use cheap old Dacron felt. It is like $1.35 a linear yard. I use it at work all the time. It wets out pretty well. I would think after you put down an initail layer of resin it would be fine for building bulk into a mold. You could use some fiberglass to make it stiffer if you wanted. If you can't find it anywhere send me an email and I will see if I could get you some. It is use in making prosthetics.

I agree on the upper post about Fibre Glast and use their "Fibre Talk" link to their message board: http://www.fibreglast.com/phpBB2/index.php which does have an automotive section.
Don't also forget to check out Fiberglass auctions at E-bay too.
If you are in So. Calif. area, I teach (also own Werksberg Products too) a free Fiberglass and Plastics ROP (state run) job training in Garden Grove too. For more information, (714) 663-6546.

I used heavy speaker cover cloth over a kids ball to make round sub boxes for my home stereo worked pretty well i might addAnonymous wrote:I've seen some ricer mags use speaker grille cloth to mold subwoofer boxes and interior parts. don't know if this will help, but it should be cheap enough i think.

Re: Mold fabric
I worked in the car audio industry for a while. When making the smooth parts with nice curves there is no better way than grill cloth, of course if you need reinforcement, you can always add fiberglass to the backside, the hardest part is dealing with heat and shrinkage. Be prepared to add bondo if needed.
yeah I know this post is like 6 years to late... lol
