System of integrated passageways in a carbon fiber boom and method thereof
A spray boom includes a body having a length defined a first end and a second end thereof. The body is formed by a plurality of layers of composite material adapted to be molded together to form an inner surface and an outer surface. A hollow cavity is defined in the body internally of the inner surface, and a channel is formed in the body between the inner surface and the outer surface. The channel extends along the length and is defined between the first end and the second end.

a first thickness defined between the inner surface and the outer surface at a location absent the first channel, the second channel, the third channel, and the fourth channel;
a second thickness defined between the inner surface and the outer surface at a location of the first channel;
a third thickness defined between the inner surface and the outer surface at a location of the second channel;
a fourth thickness defined between the inner surface and the outer surface at a location of the third channel; and
a fifth thickness defined between the inner surface and the outer surface at a location of the fourth channel,
wherein each of the second thickness, the third thickness, the fourth thickness, and the fifth thickness is at least 1.5 times greater than the first thickness.
8. The spray boom of claim 7 , wherein each of the second thickness, the third thickness, the fourth thickness, and the fifth thickness is at least 2.0 times greater than the first thickness.
9. A spray boom, comprising:
a body having a length defined by a first end and a second end thereof, the body formed by a plurality of layers of composite material that each extend circumferentially all the way around the body and are molded together circumferentially all the way around the body to form an inner surface and an outer surface, the plurality of layers of composite material including an innermost layer of composite material that at least partially defines the inner surface, an outermost layer of composite material that at least partially defines the outer surface, and a first intermediate layer of composite material arranged between the innermost layer and the outermost layer;
a hollow cavity defined in the body internally of the inner surface;
a first channel formed in the body between the outermost layer of composite material and the first intermediate layer of composite material, the first channel extending along the length and defined between the first end and the second end; and
a first line disposed in the first channel between the first end and the second end that is configured to electrically, hydraulically or pneumatically couple the first end to the second end.
10. The spray boom of claim 9 , wherein the plurality of layers of composite material includes a second intermediate layer of composite material arranged between the first intermediate layer of composite material and the innermost layer of composite material and a third intermediate layer of composite material arranged between the second intermediate layer of composite material and the innermost layer of composite material.
11. The spray boom of claim 10 , further comprising a second channel, a third channel, and a fourth channel, wherein each of the second, third, and fourth channels is formed in the body between the outermost layer of composite material and the first intermediate layer of composite material, and wherein each of the second, third, and fourth channels extends along the length and is defined between the first end and the second end.
