I'm excited to finally have our machine up and running and winding mandrels, but would really love to hear guys experiences in the resin ratio / viscosity used, and how to control the layer thickness.
For our first pipe I used a low viscosity resin ( around 5000 pc), and put the correct amount of resin per weight of fiber expected into the bath. Within about 4 minutes, the bath was almost empty, and the resin was congealing around the wind, and the strands were " parting" the resin as they were being layed. Is this normal? Is there a special technique, or a particular viscosity resin, or a special amount of tightness in the squeege device people are using to reduce wetout? Is it best to put all in, or put some in, then a little more later ?
Secondly, I generated the G-code for 1 x 60 degree wind, which resulted in 450 passes on a 30cm long, 4.5cm diameter mandrel. Needless to say, 30 minutes in, as the thickness is going past 2mm, I'm wondering what setting I have entered incorrectly?
Is there a trick to setting the layers? Is there any way of knowing how much carbon will be used?
Any experiences greatly appreciated, good or bad
