    We are attempting to replace spring steel sheet with kevlar composite

    yes. there are quide pathes on edges .. yet the mid section can not deflect greatly we understand the balance of design now.. can we use some unidirectional fabric with kevlar in resin? make the fibers of kevlar run axial direction to gain rigidity and radial direction would flex around the...

    We are attempting to replace spring steel sheet with kevlar composite

    yes.. that sounds good.. but will a sheet coil up on a spooler like the old style film feed cameras? I am thinking that the inside portion of the skin will be in compression too highly possibly and the sheet must be 26" x 40" in size.. without flexing too much from wind loads of .2psi normal...

    We are attempting to replace spring steel sheet with kevlar composite

    The design is for a Fairing to block off a radiator of a Class 8 Tractor... For class 8 trucks hood retro fit kit that is. on the L and Right of the hood next to the radiator a sheet of spring steel uncoils into a aerodynamic shape.. it cuts off a portion of the radiator to the flow and...

    We are attempting to replace spring steel sheet with kevlar composite

    We need very high rigidity about the axis of coiling and flexability in the tangential direction. So, should be use a specialty design.. like tubing of carbon fiber.. composite tubes.. interlocked between two very thin sheet or possibly a fabric of kevlar? we need to wind up the panel on a...

    We are attempting to replace spring steel sheet with kevlar composite

    Kevlar replacement: We have looked into spring steel and are considering kevlar sheets to wind up a panel/sheet nearly 26" width on to a 4"-5" diameter tube. The panel coils up with a tensioning spring and feeds out a odd shape track to define a aerodynamic surface. Can some one help consult...
