Epoxy filler material properties?

[Toblatics]

Does anyone have any mechanical properties for epoxy filler?

It is being used as a core material in a carbon laminate, so I would like to find an approximate Elastic Modulus, Shear Modulus and Poisson's ratio for it if possible.

Hi Toblatics,

What product are you talking about?

"Epoxy filler" can be anything from tooling foam to colloidal silica. Do you have a specific material in mind, or at least a specific type of product / application?

If you're looking to stiffen a panel then epoxy filler is not the right wording for it. There are various core materials you can use to give thickness and structural strength, too lazy to look for it now, but your suppliers should have what you need - as well as the required type and thickness for the specific app.

Fillers are mostly used to fill gaps up, almost zero flex and usually very hard. Not good for structural use, and as Matt said there are various ones, some are lighter or work easier when cured.
