A Bayliner thread
Gene Kearns wrote: On 29 May 2006 18:48:04 -0700, penned the following well considered thoughts to the readers of rec.boats: Vacuum "bagging" is an injection process. The bag around the dry layup allows a vacuum to develop so the resin can be sucked and pumped thorughout the fabrics and (possible) cores. No, Vacuum bagging is just that ..... using a vacuum inside of a bag. We use that method frequently in composite repair and there is no mold nor injection equipment involved. Certainly, in a manufacturing setting you could employ a vacuum to do as you suggest, but vacuum bagging, per se, is not an "injection" process. The layup process I am referring to would not be possible without the vacuum created by enclosure in a bag. I will concede that I should have considered the difference between "injection" and "infusion", as the latter term would have been a more accurate usage. |
