Corian young modulus ?

inertial · 23rd April 2009, 12:55 PM

Hi,

Please, I am a zombie with search-specify

, what is approximately the value of Young module for Corian ?
10? 20? I have no idea.....

Very thanks

Paolo

thanks, Pete

Property Typical Result Test
Tensile Strength 6,000 psi ASTM D 638

Tensile Modulus 1.5 x 10-6 psi ASTM D 638

Tensile Elongation 0.4% min. ASTM D 638

Flexural Strength 10,000 psi ASTM D 790

Flexural Modulus 1.2 x 10-6 psi ASTM D 790

Hardness >85 Rockwell “M”
Scale
ASTM D 785
56 Barcol Impressor
-----------------------------------------------------------------------------------

Thus,

E= 1.5 x 10 -6 psi ?

too "little".. where is my error?
I have issue also with conversion psi to GPa , oh my God!

Cheers,
Paolo

You are correct. I didn't even consider the number, but that is way too low. It might be a typo and they mean 10E6 not 10E-6. 1.5 x 10E6 is typical value for wood and converts to ~10 GPa.

I found another reference indicating a flexural modulus of ~9000 MPa (9 GPa). I'm guessing they are more concerned with bending properties, as opposed to tensile properties.

Thanks Pete

,

Ouch! Only 9 GPa....

I was hoping better....

A friend of mine has this strange idea to make a cabinet of corian.
But I have to design it, of course !

The only consolation maybe can be the intrinsic damping, but I am not sure of it...

Is it so good as "rumors"says ?

Cheers,
Paolo

Can't help you with mechanical properties but one builder of my NaO AEP system used Corian for the baffle and he claimed it was acoustically very dead.

Oh thanks Dr. Krekowsky

,

For sure they are very beautiful, first!

Thus, based on the claim of your builder, is possible imagine that the damping be higher than MDF .... a good thing !

I can not say for sure, but I would assume so. As I recall he used 2 1/2" sheets bonded together for the main baffle and some edge pieces to further thicken the baffle around the edges so that the black metal baffle support would not be visible from the side.

Thanks for comments Dr. Krekowsky,

This Corian start to become interesting to my eyes (my boxes will be little so the prices I hope will be not-outrageous !

)

O.T: Seems to remember me you had said in the past , you wanted experimentate also Dr. Geddes Nathans speakers kit ( I hope to remember correct ).......any news ? IMO it would be very very interesting

Cheers,
Paolo
