    Laminate curing cycle

    Hello all, I'm an FE engineer who's done mostly linear structural analysis on Nastran/Patran. I've been currently working one something outside my element with Marc/Mentat on modelling the internal stresses of a laminate as it progresses from a soft prepreg material to a hard cured laminate...

    Thickness control at sharp curvature.

    Hey compositepro, Thanks again for your input. I was thinking along the lines of a thin rubber sheet which could conform the the contour more easily than a stiffer rubber sheet under vacuum. If the solution calls for essentially a rubber male mold, then I imagine it would take more than just...

    Thickness control at sharp curvature.

    Thanks for your input Compositepro. I can see how a rubber material (ie. rubber sheet) could help even out the "vacuum pressure" in a tight corner, effectively pushing down against the "bridging fibers".

    Thickness control at sharp curvature.

    Hi i was wondering if anyone here as had experience resolving issues of over thickening at radius (example: corner of a U-shaped plate). I suspect the radius of curvature is too small at the bend, and is restricting resin flow, hence leading to areas where thickness becomes too high. A possible...
