Hi there,

i have been trying to achieve consistent smooth surface in FRP pipes lately . i was able to figure out how to negate dents, craters, crack holes ( occur due to SM Matt Folds) as well as micro holes. but i am having tough time Figuring out how to avoid this in my final product. it usually occurs at the edges of the pipe.

i was aware that in filament winding due to higher stresses at the edges of the pipes ,resin tends to squeeze out more than that of middle part . But some times it occurring even at the middle. It occurs randomly in the middle part of pipes.

Can someone please advice on what can i do to avoid this
