This question is for all the infusing experts. Do you guys bother infusing really small parts like say a 4"x4" piece? I can see it being beneficial for really large parts but seems almost unnecessary for small parts. Any thoughts?
i infuse everything even my small fuel pump covers. I can’t make anything presentable any other way lol
Mr. Dustin
that’s my dilemma as my bagged stuff are just about perfect and don’t know if it’ll be worthwhile to switch to infusing. All my molds are pretty much all setup to infuse with large flanges so it wouldn’t be a humongous task by any means. The only reason I want to switch to infusing is I’m getting tired of all the crap envolved with a wet layup. Ah hell even if I don’t infuse, I think I’ll play with it a bit to get a feel for it.
tz, i think once you try it you won`t go back. I infuse everything no matter what it is, the results are so much more consistent.

theres no way you would go back to bagging! you will kick yourself that you didnt try it years ago…
Since were on the topic of infusion vs. bagging.
Have any of you tried infusion with metal supports/flanges placed in specific area between layers of glass/carbon? I know you can do this with bagging, just not sure about infusion. Would in inhibit the resin flow at all?
An example of the layers would be: Glass-aluminum-glass-aluminum etc… until your desired thickness in that area is reached.
The metal thickness Im talkng about would be no more than .012".
Some of the more structural parts Im building for my Nissan I would feel more comfortable about if it had inlaid metal. Obviously not aluminum/carbon because of corrosion. Stainless/carbon, or, aluminum with S-glass is what I have in mind.
Usually, you add those in after the part is molded.
i don’t know if it would disrupt the flow. I know if I have some core that is too big sometimes in little sections I will have spots that did not fully saturate
I think I will have a go at it and see what happens. Thanks guys.

Why do you feel you need to have metal in the structure? Is it going to be threaded? If not, there’s sure to be a composite solution.
We use kevlar patches inside our laminates, in areas that may suffer impacts.
okay I need to order some supplies to try my hand at this. Where are you you all getting your supplies from? I usually get all my vacuum bagging supplies from airtech. Their infusion starter pack is a bit pricey. I know there are multiple threads covering all this but I’m a lazy sumbitch and if you help me out… I’ll buy you a Ferrari if I win the lotto.
Most large scale manufacturers will not sell to small accounts but let their dealers do it for them. Then those dealers can make a living too!
I use www.richmondaircraft.com but they donate to my program too!
Dude just pm me, I have a shit load of it…Ill do ya right on it.
Hybrid… pm on the way.
by the way… will this pressure pot work?

that is what I use
Here’s my Harbor “fright” one modified for VIP and working on a clear PC lid for it too for vacuum degausing.
I’d add kevlar, or core of some sort. Use metal only for hardpoints (bolts/bolt holes/thru-holes, etc)…else, bond the CF to the metal piece later (with anodizing, or a glass layer first of course.)
Thats what I was looking for. I want to increase the tear/ripping strength in areas that bolts are attached. I know that the exacty method I mentioned is used on F18’s on its hardpoints.
Im just curious to see if anyone has done this with infusion.
I just want to re-inforce areas that might be subjected to ripping or get torn by road debris. Im not necesarily trying to increase the stiffness of the part.
I have 12oz CF for adding structural support, I guess I should have mentioned exactly what I was wanting to do.
Here is an example of what Im talking about. This is my upper bumper support for my nissan. The 4 holes you see is where I would like to interlay SS or aluminum .
