The previous page showed the four layers of carbon fiber dry goods. The photo at left shows the laminate as the vacuum bagging materials are being pulled off this side of the part. This side of the part is ready for secondary bonding, since the surface is left with a finely rough texture. This texture could be a final surface however, like the inside of an OTA tube where a non-glossy, textured surface is desired.         Here is the four layer, 40"x50" carbon fiber panel, dull (finely textured) side up. Weight of the carbon fiber dry goods was 1113 grams. Estimated finished panel weight was 1688 grams, as noted on the previous page. Actual panel weight was slightly better, 1650 grams, 32.6% resin by weight of the part.             Note how consistent the surface quality of the part is. Both the lay of the twill and the surface quality.         Goto the next page to see additional images of this panel and additional parts.   To learn why an oven is an important part of advanced composite fabrication, please click here.
