How to Calculate Shrinkage

How to Calculate Shrinkage

(OP)
Where or how can i calculate shrinkage for various resins, methods and resin to glass ratios related to FRP. Thank you for your help in advance.

RE: How to Calculate Shrinkage

Consult the manufacturer's data sheets.

Here's a start: http://www.ides.com/


RE: How to Calculate Shrinkage

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

RE: How to Calculate Shrinkage

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.  

RE: How to Calculate Shrinkage

(OP)
"related to FRP".....so its thermoset

RE: How to Calculate Shrinkage


"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.


Cheers
