The invention relates to a composite material thin-walled tube and a manufacturing process, the composite material thin-walled tube is made of a high-performance fiber reinforced resin composite material, the high-performance fiber reinforced resin composite material comprises a fiber reinforced body and a resin matrix, the fiber reinforced body is etched high-performance fiber, and the resin matrix is a resin matrix. The whole composite material thin-walled tube has a certain length-diameter ratio, and a chamfer is arranged at the head end; a thin-wall layer is arranged in a gap in the composite material thin-wall pipe, a section formed by the thin-wall layer and an outer wall layer of the composite material thin-wall pipe is a special-shaped section, the special-shaped section is structurally divided into a force bearing area and a binding area, and the force bearing area and the binding area respectively form a force bearing layer and a binding layer of the thin-wall pipe in the length direction of the thi
