Fiberglassing MDF

How strong is a bond between fiberglass and MDF?

It seems as if it would be relatively easy to break the fiberglass off of the MDF, because you would only need to remove the top few layers of MDF to get the fiberglass off.

Right?

Strong. You act like mdf is balsa wood.

Well in my experience MDF is kinda brittle when it comes to a small area...

MDF and resin bond great. the bond is unbreakable becuase the resin soaks into the wood. Resin pretty much sticks to everyting except vynal and rubber.

Oh I must have typed in invisible when I said "strong"

Whenever I glass right to MDF it always stays and never moves.

Fglass doesnt like to stick to: Glass, plastic, vynl, some rubbers, some metals... tile I think...

My mdf ring split completely in half before the ring detached from the fiberglass....The bond is stronger than mdf itself.

well okay let me draw something up in paint.

you're saying that this could never happen? it seems feasible to me.

IF your picture is showing the wood breaking first it's possible. But resin by itself is very brittle. Resin would break before the mdf. However if mat and or cloth was involved the mdf would probably go first. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Exactly my point. I'm askeered that i'll have problems with this paper-like wood we call MDF.

all depends on what that part is being used for. if its the pressure inside the box that youre worried about, the glass will go before the mdf, and if the glass is that brittle, then you have bigger fish to fry than the seperation of MDF.

if its just a cosmetic foot or an amp rack brace or something, you wont need to be able to jump on it.

resin is used in SPL boxes made out of MDF.

nuff said, you shouldnt run into any issues.

brian, if you are that scurred - drill a few small holes in the MDF - and glass a good 10" in on each piece of MDF.

the resin will seep into the little holes, and you will have a nice 20in^2 or more of surface contact.

make sure you glass EACH SIDE of the thing.

wont be going anywhere... ever. //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif
