Abstract

A parachute is formed from a non-woven composite material. The non-woven composite material is formed by fusing a plurality of mono-filament fibers between thin layers of plastic. The fibers are positioned in directions within the material according to the stresses on the panels of the parachute. The panels of the parachute may be joined using fusing, adhesives or other non-sewing methods. The material may also be formed to have a three dimensional shape for each panel.

Claims

1. A parachute comprising:

a canopy comprising a plurality of panels, wherein at least one of the panels is manufactured of a laminated material having a lower plastic film, an upper plastic film and a plurality of mono-filaments positioned there-between.

2. The parachute according to claim 1, wherein each panel of the canopy is manufactured of the laminated material.

3. The parachute according to claim 1, wherein the plurality of mono-filaments includes a first plurality of filaments positioned in a first direction, a second plurality of filaments positioned in a second direction different from the first direction

4. The parachute according to claim 1, wherein the plurality of mono-filaments includes a first plurality of filaments positioned in a first direction, a second plurality of filaments positioned in a second direction different from the first direction and a third plurality of filaments positioned in a third direction different from the first and second directions.

5. The parachute according to claim 1, wherein the plurality of mono-filaments are positioned in a plurality of directions corresponding to directions of stresses in a particular panel in the canopy parachute.

6. The parachute according to claim 1, wherein the plurality of panels includes at least one rib, and wherein at least one of the at least one rib comprises the laminated material.

7. The parachute according to claim 6, wherein the plurality of mono-filaments includes a first plurality of filaments positioned in a first direction, a second plurality of filaments positioned in a second direction different from the first direction and a third plurality of filaments positioned in a third direction different from the first and second directions.

8. The parachute according to claim 6, wherein the plurality of mono-filaments are positioned in a plurality of directions corresponding to directions of stresses in a particular panel in the canopy parachute.

9. The parachute according to claim 1, wherein at least one of the panels made of the laminate includes one or more electrical devices and/or wires for communicating electrical signals.

10. The parachute according to claim 9, wherein the electrical devices comprise a sensor.

11. A panel for parachute or parafoil comprising a laminated material having a lower plastic film, an upper plastic film and a plurality of mono-filaments positioned there-between.

12. The panel according to claim 11, wherein the plurality of mono-filaments are positioned in a plurality of directions corresponding to directions of stresses in a particular panel in the canopy parachute.

13. A parachute comprising:

a canopy comprising a plurality of panels, wherein the plurality of panels includes a plurality of ribs, wherein each rib is manufactured of a laminated material having a lower plastic film, an upper plastic film and a plurality of mono-filaments positioned there-between.

14. The parachute according to claim 13, wherein the plurality of mono-filaments are positioned in a plurality of directions corresponding to directions of stresses in the parachute.

15. A method of construction of a panel of a parachute, the method comprising the steps of:

laying down a first thin sheet;

laying a plurality of mono-filaments on the first thin sheet;

laying a second thin sheet over the plurality of mono-filaments;

fusing the first thin sheet, plurality of mono-filaments and second thin sheet to form a laminate; and

cutting the panel of the parachute from the laminate.

16. The method according to claim 15, wherein the step of laying the plurality of mono-filaments includes the step of laying the mono-filaments in a plurality of directions corresponding to directions of expected stresses on the panel.

17. The method according to claim 15, further comprising cutting a plurality of panels from the laminate and assembling the panels to create a parachute or parafoil.

18. A method of construction of a panel of a parachute, the method comprising the steps of:

cutting a plurality of panels having a predetermined shape for assembly into a parachute canopy from a sheet of fiber reinforced plastic film;

assembling the plurality of panels into the parachute canopy; and

fusing the plurality of panels together.

19. The method according to claim 18, wherein fusing comprises using at least one of an adhesive and ultrasonic fusing.
