Consult the manufacturer's data sheets.

Here's a start:

Like Pud says, or if it is an unusual situation and not covered by manufacturers data, lay up a small section and measure it.

Are we talking thermoplastic glass reinforced injection molded parts here? Or are we talking Thermal set fiberglass? There is a lot of difference in how these two types of material respond.

"related to FRP".....so its thermoset

"Fibre Reinforced Plastic/Polymer" - could be any or all of the above I guess - looks like op has found what he wants anyway...

Manufacturer's data sheets still contain the data requested.
