Abstract
Laminate structures and methods of making laminate structures having overwrapped laminate edges which resist delamination and fraying or including one or more stabilizer laminates which afford greater radial and torsional rigidity in longitudinally slit tube structures.
Claims8
A laminate, comprising:
- a laminate having a first edge and a second edge, said laminate having a structure which acts to bias configuration of said laminate from a substantially flat condition toward a longitudinally slit tube having said first edge disposed in opposed relation to said second edge defining a longitudinal slit;
- and
- a stabilizer having an unsecured portion disposed between a pair of securement portions, said securement portions secured to a first face of said laminate to dispose said stabilizer in overlaying fixed relation to said laminate, said laminate in said substantially flat condition disposes said unsecured portion in a corresponding substantially flat condition, said laminate configured as said longitudinally slit tube disposes said unsecured portion of said stabilizer in an arcuate condition inside of said longitudinally slit tube, said arcuate condition having a radially opposed curvature to said longitudinal slit tube.
A laminate, comprising:
- a laminate having a first edge and a second edge, said laminate having a structure which acts to bias configuration of said laminate from a substantially flat condition toward a longitudinally slit tube having said first edge disposed in opposed relation to said second edge defining a longitudinal slit;
- a pair of bypass apertures which communicate between said first face and a second face of said laminate;
- and
- a stabilizer having an unsecured portion disposed between a pair of securement portions, said pair of securement portions of said stabilizer correspondingly passing through said pair of bypass apertures to secure to said second face of said laminate to dispose said stabilizer in overlaying fixed relation to said first face of said laminate, said laminate configured as said longitudinally slit tube disposes said unsecured portion of said stabilizer in an arcuate condition inside of said longitudinally slit tube, said arcuate condition having a radial curvature opposing said longitudinal slit tube.
