Autoclave

 Finishline composite procedures and techniques are performed with the understanding that quality comes first. There are products out there that are giving the composite world a bad name. Here is why, first they are using polyester resins. They might look glossy and shiny when you first see them. Shortly after they set in different temperatures, (summer, winter) the part will start to get very dull.It will take on a yellowish look to it, start to crack, and change shape.

 Another thing is, they use died, black fiberglass fabric on the top layer. Or just a really low grade carbon. They use all fiberglass cloth on the additional layers (the layers that the eye can not see). Because they don't have the right equipment (to costly) they lay it up bucket, and brush style. What happens there is the part is full of voids, and air pockets. They just saturate the part with an automotive clear. That’s why everything starts fallen apart; the clear is a different chemical structure. In time, and temperature it delaminates. You’re really not even getting a real carbon part.

 A short story of our method (aerospace way). We use nothing but the best high-temp, high-strength epoxies and aerospace grade carbon (lighter, stronger), or prepregs. Depending what the job calls for then we lay it up (another story). It goes through a vacuum debulking stage, where different types of materials get the carbon fiber to take its new molded shape.

 The autoclave awaits the final process. The part will be put under vacuum, pressure, and heat. What that does is, it forces all the excess resin (that the carbon fiber does not want), all the trapped air, and gasses out of the part and through the vacuum lines. Since the part is under extreme heat conditions it is post cured. Within hours and it comes totally finished. With no added chemicals, end result - structurally (bulletproof), cosmetic (high gloss, deep shine). The best thing of all is it will always look, and fit the same way as when you first seen it.
