angle-aluminum vs angle-fiberglass

[rnbraud]

Hello all,

 

Have a simple materials question. I need an 1 foot long section of right-angle aluminum.

 

Unfortunately, I need a piece that is about 3 1/2 inches on one side and 1 1/2 inches on the other.

 

Now I know I can find some 1/8" thick 3x3 inch aluminum angle.

 

However, I was wondering if I couldn't must make mo own out of fiberglass.

 

If so, in rough figures, about how thick should I make it so that is is equivalent in strength to the 1/8" aluminum angle?

 

I am confident the flat pieces of the angle-fiberglass will be strong enough.

 

My concern in in the 90 degree angle part and how strong fiberglass is in that configuration.

 

Thanks for any and all comments.

 

Later.
