I've been looking around for some kind of comparison chart of different covering materials for a while... so far the only one I've come across was in a transcript of the MARCS National Sailplane Symposium from 1987 that Oliver Wilson let me borrow (thanks Ollie! I'll get it back to you, promise!). A fellow named Lee Murray ran some tests and presented the info at the symposium.....
Breaking Strength- Monokote, 24-33 Lb/in. at break Ultrakote, 27-41 Lb/in. at break Elongation- Monokote, 48-87% elong. at break Ultrakote, 80-133% elong. at break Modulus- Monokote, 7.7 Lb in. at 1% elongation Ultrakote, 6.2-7.5 Lb in. at 1% elongation Impact Strength- Monokote, 2.5-3.2 Joules Ultrakote, 3.7 Joules Tear Resistance- Monokote, 36 grams Ultrakote, 46 grams I honestly don't know for sure if this information is entirely accurate anymore as the covering manufacturers may have changed formulas or manufacturing procedures that could alter the characteristics of the films...If anyone has more up to date info it would be greatly appreciated. ----- Original Message ----- From: "Bill Rakozy" <[EMAIL PROTECTED]> To: "RCSE" <[EMAIL PROTECTED]> Sent: Friday, March 29, 2002 1:29 PM Subject: [RCSE] Monocote v.s.
