This invention belongs to the field of cable technology, specifically a thin-walled oxygen-barrier high-temperature resistant cable, comprising a conductor core and a thin-walled outer sheath. The conductor core has a high-temperature resistant insulation layer made of polyetheretherketone (PEEK) composite material on its outer side. Between the high-temperature resistant insulation layer and the thin-walled outer sheath, from the inside out, are sequentially arranged a ceramicized oxygen barrier layer and a flame-retardant reinforcement layer. The ceramicized oxygen barrier layer is a nano-modified ceramicized silicone rubber layer with a thickness of 0.05–0.15 mm, including an outer layer doped with silicon carbide whiskers and an inner layer doped with zinc borate. This invention prepares an ultra-thin ceramicized layer through gradient doping, resolving the contradiction between thin-walled design and oxygen barrier properties, and effectively improving the interfacial peel strength. This reduces the cable's outer diameter and bending radius, making the cable lightweight and suitable for high-dynamic applications.

This invention belongs to the field of high-performance thermoplastic composite granule preparation and process optimization technology. Specifically, it relates to a method and system for determining the optimal process for twin-screw extrusion preparation of carbon fiber / polyetheretherketone (PEEK) granules based on numerical simulation and multi-objective optimization.

With process temperature and extrusion speed as decision variables, a non-dominated sorting genetic algorithm is used for multi-objective global search to obtain the Pareto optimal solution set, which is then ranked and optimized to output recommended process parameter combinations. This invention's method can reduce the risk of thermal degradation and fiber damage while considering the mixing effect, and reduces the cost and cycle time of trial and error.

This invention discloses a composite structure isolation sleeve, comprising an inner sheath, an intermediate sheath, and an outer sheath. Both the inner and outer sheaths are polyetheretherketone (PEEK) sleeves. The intermediate sheath includes several non-magnetic laminations stacked sequentially along the axial direction. Adjacent non-magnetic laminations are insulated from each other, and the inner walls of all non-magnetic laminations are fitted to the outer wall of the inner sheath. This invention achieves a balance of key performance indicators, including low eddy current loss, high mechanical strength, and high sealing reliability. The non-magnetic laminations, due to their low permeability, avoid becoming part of the magnetic circuit. The insulation between the non-magnetic laminations divides the continuous conductor path into multiple insulated micro-conductive loops, significantly cutting off large-scale eddy current paths that may form in an alternating magnetic field, thereby reducing the total eddy current loss of all non-magnetic laminations in the alternating magnetic field.

A wear-resistant coating (nano-alumina modified epoxy resin) on the outer surface of the third insulation layer forms a dual wear-resistant protection system with the third insulation layer (polytetrafluoroethylene), significantly improving the surface wear resistance compared to conventional insulated wires. During installation, the coating resists frictional damage caused by dragging. Furthermore, the tape-type adhesive surface and release paper design reduce vibration friction by quickly fixing the wire, further reducing the probability of wear and significantly extending the service life of the insulated wire.

After adding a lubricant, the friction coefficient during system sliding is reduced to the order of 0.001, resulting in super-lubricating phenomena, and the wear resistance of the material is also improved.

This invention provides a highly thermally and electrically conductive polyetheretherketone (PEEK)-based composite material based on reversible conversion and its preparation method. The invention provides a reversible chemical conversion method based on polyetheretherketone (PEEK) and soluble polyetheretherketone-1,3-dithiolane (PEEK-dithiolane). This method converts the semi-crystalline polymer PEEK, which is insoluble in most solvents, into a soluble dithiolane derivative.
