Brian, Most fibers used for laminating, including E and S glass and carbon fiber, have a coating applied to the individual strands to enhance the adhesion of whatever resin system would be used to glue everything together. That coating has a 5-year shelf life. My thought is if the shelf life is getting ready to expire, then the dealer would reduce the price to move that batch before it expired. The resin will not wet out old fiber very well - been there, done that. Your results may vary. Sid Wood, KR-2 N6242 Mechanicsville, MD sidney.w...@titan.com
-----Original Message----- I was looking online yesterday for good prices on carbon fiber and found this site. http://www.advancedcompositetraders.com/inven.html They have style 282 cloth for $12.50 a yard. I checked in my last years Aircraft Spruce catalog and they had 282 cloth for $25.75 a yard. This years catalog has it for $16.50 a yard. This seemed strange so I looked in Wicks and they have 282 cloth listed at $28.20 a yard and they also have a C282 commercial grade cloth for $17.19 a yard. I am assuming that the online source and ACS, at least this year, carry the commercial grade. Would anyone happen to know what the difference is? Seems that the commercial grade is 5.8 oz and the other is 5.7. I know that the commercial grade is stronger and lighter than glass so I am assuming that for a KR that there is realy no reason to go with the other type that is over twice the cost.
