Importance of closed mold and short fibers
• Directional properties• High process time• High skill requirement• Intricate shapes not feasible• High part cost• Low volume
Open mold continuous fiber
• Near isotropic properties• Quicker cycle time in minutes• Minimal skill dependency• Near net shape part and ability to mold complex shapes• Low part cost• High volume
