So after getting too many pin holes in the carbon parts i have done, i am looking to switch to infusion. But i had a few questions maybe some of you guys could answer.
Also any other suggestions on getting a pinhole free infused part would great
I took a different approach. After countless waste of cf and resins, I finally give in a tried the MTI hose. For a beginner, it is very forgiving of the noob mistakes. Couldn’t get pinholes all gone til I tried the hose. Pulled my first part and it was flawless. O yea and don’t forget to degas. I’ve had only failures without degassing. But others have had success. Like I said, I’m a beginner
As for uv clear, I decided to worry about it after infusion. That way it didn’t matter that much if the surface wasn’t shiny. I was gonna lightly sand and spray auto uv clear after.
Here’s some pics of the product before clear coat. Infusing a panel as we speak so I will post the result in a day.
Just pulled this one out of the mould. Gonna clear coat it after I cut the part out.
Try the In mould coating from German Advanced Composites. Works perfect with infusion and epoxy
Great looking part!!
ok i bought the mti hose but not the in mold coating. i want to see how well the initial part comes out first.
If the hose works i may go back and remake some of my other parts that have pin holes.
any other suggestions that would help get “perfect” parts? how much vacuum should i pull?
Read the MTI hose thread in products talk. But the most important things are:
1: 100% vacuum tight bag (it’s all about practice)
2: absolute vacuum <20mbar
3: degassed resin
if you then use the MTI hose you will get a perfect part.
Duratec has some good clear.
Here is the fender mold (yes it is coated, sanded and waxed already just not shown). Should i just run the hose along the outside edge and feed from the center out? Thoughts?
