Multihelical composite spring

A helical spring comprising:

• a multi-helical unit including a number of layers of composite material disposed in a multi-helical configuration,
• the multi-helical unit including layers of at least a first strand, a second strand, a third strand, and a fourth strand of composite material;
• the first strand disposed in first coiled configuration, the second strand disposed in a second coiled configuration, the third strand disposed over the first strand and the second strand, the third strand disposed in the firs coiled configuration;
• the fourth strand disposed over the first strand, second strand, and third strand, the fourth strand disposed in the second coiled configuration;
• and
• the first strand, the second strand, the third strand, and the fourth strand interwoven and bonded together in a single spring unit.

A helical spring comprising:

• at least a first set of layers of composite material distributed in a first coiled configuration, the first coiled configuration extending from a first end to a second end;
• at least a second set of layers of composite material distributed in a second coiled configuration, the second coiled configuration extending from one end to another end;
• the first set of layers and th second set of layers interwoven and bonded together in a crisscross configuration, each layer of the first set of layers overlies a layer of the second set of layers at multiple intersections to form a single spring unit;
• and
• the composite material for he first set of layers and the second set of layers comprising a polymer matrix reinforced with a plurality of fibers.
