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.

A method of forming a decorative panel includes pressing a decorative layer in relation to a substrate. The decorative layer includes one or more decorative elements, such as one or more of coloration, text, graphics, or the like.

A composite material structure body production method includes a layering step of layering a plurality of fiber sheets to form a layered body having a deforming portion extending in one direction, and a forming step of performing bend-forming along a deforming line contained in the deforming portion and extending in the one direction, thereby causing the deforming portion to deform. The layering step produces the layered body in such a manner that the shape of the deforming portion is a shape wherein: the cross-section shape in the one direction and the cross-section shape in an intersecting direction that intersects with the one direction are bent or curved; and the length in the intersecting direction changes along the one direction.

The present disclosure is directed to a process, device, and system for recycling a composite material comprising a base material composited with a polymer material, which may can include a process comprising applying a non-ionizing radiation to the composite material and contacting the composite material with H.sub.2O until the polymer material is substantially removed from the base material to produce a recycled base material.
