Material Request - Fiberglass

Material Request - Fiberglass

Material Request - Fiberglass

(OP)
Does anyone have a good material definition for fiberglass?  I have ctopher's materials database from 2008, but don't see a choice for fiberglass.

Thanks in advance,

Did you check Matweb.com?

RE: Material Request - Fiberglass

Be very careful with how much faith you put in whatever definition you do find.  As a generic category fiberglass has roughly as much variation in material properties (density, yield strength, modulus of elasticity) as wood.  Imagine not knowing if the numbers that you used in your design were for balsa or oak.

And remember that fiberglass as a material is not isotropic.  it can be highly directional when used in a tape form or it can be quasi-isotropic when used as fabric layed up at alternating orientations.  If you are just looking for a density to get mass properties check the cured properties for the type of material you are wokring with.  And don't try and do an FEA analysis with Cosmo on it, it just won't give meaningful results if it's not intended to analyize fiberglass.  If you just want some cool visual properties (which I would like too) I'm not very familiar with that sort of thing.

RE: Material Request - Fiberglass

I didn't add any type of composite materials because of the many variations, also didn't have time to.
I'm hoping to update the database...someday.
We have a composite guru here, someday I will pick his brain for help.

Good comments from all.

I am not doing any FEA so the directional issues are not a concern.  If it were I would be approaching this more from the perspective of composites.

Actually all I was looking for was a general density, appearance, and cross section.

Just did a project for the FAA where I looked up the pound density and found it to be about 110 pcf, which I used.
