Carbon and glass fibre profiles in electrical engineering

The unique electrical engineering properties of fibre reinforced polymers make DPP profiles interesting for use in electrical engineering components. The composite profiles can be made electrically conductive by reinforcing them with carbon. But by reinforcing them with glass fibre or aramid fibre, they become electrically insulating.

Micro-pultrusion enables these components to be produced with very thin shell thicknesses and at very low tolerances. These possibilities, combined with the low weight and the good mechanical and chemical properties, make it beneficial to use DPP micro-profiles as structural parts in electrical engineering components.

    Structural material for measuring feelers, gauges, sensors and probes

    There are various reasons why glass fibre profiles are used as reinforcement and/or stiffening in measuring and inspection equipment. Various measuring feelers, gauges, sensors and probes are manufactured with DPP micro-pultrusion profiles.

    For example, carbon micro-tubes are used as frame elements in measuring feelers and gauges. Besides the favourable mechanical properties, the low coefficient of expansion of carbon is crucial. This makes the gauges less sensitive to temperature changes.

    For sensors and probes that function in a chemical environment, the use of composite profiles as packaging or frame elements can also be beneficial. DPP carbon tubes and rods, for example, are used in the probes of liquid-level sensors that measure the coolant level or the electrolyte level in batteries. The possibilities are truly infinite.
