Abstract: A pressure vessel for storing a fluid, comprises an outer jacket applied to a plastic core container, the outer jacket comprising a first fibre-reinforced reinforcing device with one or several wound layers comprising first fibres that are embedded in a first matrix material, a second fibre-reinforced reinforcing device formed on the outside of the first device and with one or several wound layers comprising second fibres that are embedded in a second matrix material, and an impact-absorbing thickening of the outer jacket in a polar cap region of the plastic core container. The thickening is formed in that one or several wound layers that are thickened in the polar region are formed in at least one of the reinforcing devices with a face opening that is larger than a face opening of other non-thickened wound layers in at least one of the reinforcing devices.

Abstract: A guide roller for wires, comprising a coating support (1) in the form of a hollow cylinder which is slidable parallel to the longitudinal direction, on which a coating (4) is fixed permanently by adhesion, and having guide grooves for the wires, and which is supported on a hub part by a stabilising support (2) made from CFP or metal, wherein the coating support (1) is made of CFP and is secured on the stabilising support (2) only by a cylindrical or conical press-fitting, avoiding the use of a screw connection

Abstract: Transport pipe for high viscosity materials, in particular for concrete. The transport pipe includes an inner pipe (10) made of an abrasion-resistant plastic, at least one metallic joint element (12), as well as a reinforcing jacket (14) which envelops at least the internal pipe. In order to ensure a reliable and enduring joint between inner pipe and joint element, it is proposed in accordance with the invention, that the radially projecting collar of the joint element is defined by a ring-shaped end face (20) and by a thereto joined ring step (22) extending radially towards the inside of the pipe and recessed axially from the ring-shaped end face, and wherein the plastic material of the inner pipe (10) engages in the ring step (22) from the inside of the pipe.

Abstract: Pressure vessel for a pressurized medium which is capable of flow, providing a first reinforcement composed of fibers which are applied as a winding and which are embedded in synthetic resin, wherein in addition to the first reinforcement, a second reinforcement is provided, wherein said second reinforcement has an elongation at fracture which is lower than that of the first reinforcement, wherein the first reinforcement, considered alone, is sufficient to entirely absorb the forces resulting from the pressure of the medium in the pressure vessel, and wherein means are provided which are suitable for indicating a fracture of the second reinforcement.
