Thanks maca55 !
About the weight... my aim was only to make experience with fiberglass and molds, not to reduce the weight of the model, but here is the results : 1. Original canopy : 19.3gr (0.68 oz) 2. Carbon fibre canopy (2 layer of carbon and 1 of fiberglass) : 20gr (0.70 oz) 3. Fiberglass canopy (painted) : 15gr (0.53 oz) I forgot to say that when trying to hide some imperfections on the carbon fibre canopy, i've painted with 2 coats of clear lacquer. So i think the weight before the lacquer was 1 or 2 grams less. |

Can I ask a few questions--
The PVA, is that Poly Vinyl Acetate? Is that a glue or some other product? (What's the UHU stuff?) I assume the glass is laid up right over the stock canopy. I take it some sort of release agent was used. Was that the PVA? Or something else? What kind of resin did you use? Was it possible to clean the stock canopy for reuse when you were done? |

Hi !
PVA is : Polyvinyl Alcohol Release Agent It is used to form a barrier for the epoxy resin, so you can remove "easily" the piece from the mold. http://www.eagerplastics.com/pva.htm UHU Glue is almost the same thing as 3M 77 , it's a spray glue. Exact, the PVA is the release agent, so you can use the original canopy Resin used : West System resin 105 The stock canopy was cleaned just using warm water and some soap it's intact. Thanks for visiting my blog Dave |
