Both foams are 2# density, very similar in weight.

I think the rigidity of the foam is important. You could not put on one layer of glass on the wings, then remove the foam and expect the properties to be the same. This is a "Sandwich" construction, which, to me, means that the stuff in the middle is integral to the properties of the end product. Your result WILL vary. Dan.

I am familiar rigid foams. My question is how much rigidity of the foam is actually required, once the carbon fiber or glass is cured. The minicell foam is semi rigid, flexible, can't be broken and springs back when compressed. It has 2/3's of the compression strength of the same 2# polystyrene (pink stuff they by at Home Depot) -----Original Message----- From: krnet-boun...@mylist.net [mailto:krnet-boun...@mylist.net] On Behalf Of larry flesner Sent: Friday, August 12, 2005 8:52 PM To: KRnet Subject: Re: KR> Foam > >I am looking at 2# Minicell foam.

The foam used in constructing a KR is a "rigid" foam ,and when 1 or 2 inches thick, will flex very little without breaking. The foam used in the KR will not compress without damage. Could you give additional info on what exactly you are looking at?
