Abstract: A carbon fiber boom structure for an agricultural sprayer boom, the boom structure including an elongated upper carbon fiber tube, at least one elongated lower carbon fiber and a carbon fiber/resin matrix uniting structure bonded to each of the carbon fiber tubes to hold the tubes in a spaced apart position. The uniting structure being formed in a winding operation by applying windings of a carbon fiber string with a liquid resin around portions of the tubes, the windings and resin matrix defining an inner primary layer and an outer primary layer, wherein the inner primary layer is bonded to a surface portion of each tube while the outer primary layer is bonded to a remaining surface portion of each tube to completely, or essentially completely, envelope each tube by the portions of the two primary layers.

Abstract: A connector body having a first end portion defining a first end face of the body and an opposite second end portion defining a second end face of the body, the first end portion including a first peripheral groove with a first sealing ring, and the second end portion including a second peripheral groove with a second sealing ring, an intermediate portion of the—body defining a peripheral surface extending between the first sealing ring and the second sealing ring, the peripheral surface to be covered by the retaining glue for bonding the body to the tube, a glue flow passage at the first end portion extending transversally to the first sealing ring, and a glue injection channel extending from the first end portion towards the second end portion and including a glue injection port in the first end portion and a glue ejection port at the peripheral surface.
