'Talk about consumables…
industrialized . . . . cerritos one of them they did that but on a smaller scale . . . that would be funny a joint that does car stuff also makes compsands . . .
thanks that’s pretty cool .
Oh my God! You could hand lay that up in about 10 minutes. What a waste of time and materials!
Haha, yeah.
Hey Greg, did you notice they also used poly instead of epoxy on carbon? When they mentioned “now we add the catalyst” I was like…wha?!
I think the video just serves to give the basic outline of what goes on when performing infusion for those interested or doing research.

I know there are applications for this and I’ve seen some good stuff but to a production part like this, using this method … no … no … just no. And yea, polyester resin … no.
could that have been vinyl ester?

I have to disagree with you some on this one Greg. Yes Airtech is in the business of selling all the materials used. You could have cut back on some of what they used and got just as good a part.
But VIP can produce near Autoclave quality in the part if done properly with 29"Hg of vacuum. It is being used extensively in areospace production. There is no way you could produce the same laminate with hand layup of Carbon. So not a waste of time for some.
The resin is probably Vinylester for that is what Airtech sells. And many Vinylesters including theirs have properties that are much better than even Resin Research epoxy.
That video was produced in thier factory in Huntington Beach CA. I’ve been there and seen them do infusion a few times.
i think greg is saying do a handlayup with bleeder and vac
a lot quicker and easier
alot of aircraft parts are done without infusion
I would say the video is interesting and informative.
Informative enough to confirm what Ive suspected about VI:
wrt to surfboards, its a waste of time and money.
Unfortunately, its not enough to say that VI can yield near autoclave quality laminates.
It would be more prudent to say, the part, due to performance or customer demands, requires the use of autoclave or hi-pressure VI. Large Carbon Fiber sailing masts being a perfect example.

The main thrust behind the development and ‘popularity’ of VI has been the regulatory requirements for reduced styrene emissions, particularly for large open molding such as in boat mfg. VI is a closed molding process, therefore cleaner and better for the environment. But so is hand layup of 100% solids epoxy resin. And yes there are other advantages, but that has more to do with molding in general rather than VI.
It is clear to anyone watching it, that it is a product promotion video, and thats fine. Its just that, as an informed ‘consumer’, I aint buying 
Greg after having dealings with EPA recently i can see the merits of this method… they arent to fussed on what we put in the bin… they want reduced emmision into the atmosphere, this is one way to acheive that.

Silly,
I still dont agree that doing a hand layup on a part like that car hood then putting Perf, Bleeder, Bag, Tape etc. is easier than VARTM/VIP. It’s really about the same amount of steps bagging wise and you’ve still got to wet everything out by hand all while smelling the vinyester or polyester.
Carbon Fiber is very stiff and is hard to do hand layup good. So to get a good part you have to have some type of vacuum bag especially if there are any tight radius.
I helped do a resin infusion demo at one of the Cerritos College surfboard events (microphone and all) using Greg’s epoxy. I made sure that Greg’s epoxy was used and that pictures of that event with his epoxy in them got posted here on Sways, they did. For those watching, that demo did not go so effortless because one of Terry’s students wanted to dasiy chain the parts (we infused about four seperate parts at the same time). I told him it would not work but he insisted and we were scrambling to redo feed lines in the middle of the infusion. But at least everyone got to see what not to do if you want quality which was probably good, but might have confused some.
Yeah I agree most parts in areospace are not done using high vacuum infusion. But it is acknowledged (which is a huge thing in that industry) as being good for some things. Hand layup is not. Most parts are done using prepreg and vacuum bagged in an autoclave.
I don’t really see infusion being used for conventional surfboards. But for boards like Aviso yes, unless they have access to an autoclave. High vacuum Infused Balsa skins might be pretty nice too 
hey glenn
i dig infusion
at some stage i want to make some molds of an fcs type with plugs and manufacture my own fins with infusion
