Hello, I saw a video of ifusion method, but with a different variation, that don0t use a tube to introduce resin, only use one tube to extract the air and excess of resin. 

^^

Errrrrrr, how is a curing oven running at 80 C with 30psi bag pressure the same as an autoclave running at 150 C and 2000psi vessel pressure?!?!?!
Its NOT! And that's the very reason the purchase/running costs of an autoclave are so high and in turn is the very reason that the parts will ALWAYS BE SUPERIOR.

If anything I would say that putting prepreg in a composites oven is a false economy because your simply not getting the full potential of the materials, although I can see it as a very clean and pro way to work and for this reason some people would prefer to use it even without access to a clave...

But if I took a punt I would also say that a bagged prepreg in an oven VS a good infusion in the same oven at the same temp/time would produce a similar result... Its the autoclave conditions that produce a specific end product that YOU CAN NOT FAKE or reproduce any other way...

Kev.

I dont know where youve guessed these figures from but there completey inacurate? The vacum ovens we have at work run upto 250c and will pull around a steady 250psi of vac. IDEAL for non structural parts (interior trim, small bracketry, robotics cover panels etc).

With regards to being faked, correct the overal performance strength wise cant be matched, but the visual effect is easily faked.
