Hello ,
This is a great forum and I have gained immense knowledge here . Thank you guys !
After getting all supplies from easycomposites
I infused many carbon sheets on glass and a perfect glossy finish.
This is my first part I’m infusing in a mould.
Attempt 1 - pinholes towards the inlet side and relatively very less towards the vacuum side
( pinholes exactly between the fabric weave pattern )
It’s a 26”x 20” mould vacuum spiral was all around the flange of the mould and inlet in the center.
Mesh was right till the edge of the carbon fabric and spiral over the mesh.
This infused very fast approx 8-10 mins
Attempt 2 - pinholes all over the part. This time I infused from the side. Resin inlet spiral along the 26” side. I cut the mesh short and the spiral was over the peelply and carbon fabric. On the opp side I used two layers of the mesh on the flange and silicon connector in the middle.
This took about 20-25 mins to infuse.
Both times it was a perfectly sealed bag leak tested for 30 mins.
Where am I going wrong ? How do I get a pinhole free finish ?
Also which is the ideal way to place the inlet and vacuum on such a mould .
Really appreciate some help, thanks in advance
