Carbon and glass profiles in unmanned flight

In flight, fibre-reinforced polymers have been used for quite some time now. The majority of the structural components of modern aeroplanes are made of composite materials. Particularly the good mechanical properties combined with the low weight enable a considerable reduction in weight.

Weight has always been a determining factor. In view of increasingly expensive fuel and environmental pollution, the importance of low-weight materials has become a critical issue and the benefits of using them has become hugely advantageous.

    Carbon profiles as trailing edges, leading edges, spars and other frame elements

    The structural properties of DPP pultrusions have a very wide range of applications in aerospace.

    A number of typical applications of carbon or glass fibre reinforced profiles are:

    • Trailing edges
    • Leading edges
    • Spars
    • Purlins
    • Wing rods
    • Cap strips
    • Frame elements
    • Tow and push bars

    DPP pultrusion profiles are used, among other things, for the development and production of ultralights and drones or unmanned aircrafts (UAV).


    Laminated-in carbon strips or rods in glider and ultralight wings

    The modern plastic wings of gliders or ultralights are assembled to scale.
    A modern development is the use of pultruded carbon rods or strips as small sparcap material. The carbon profiles can be directly laminated in between the other fibre layers of the skins or web plates. The most important advantage here is the very high and reliable quality of the DPP pultrusion profiles. Moreover, it saves a great deal of manufacturing time, as laminating the unidirectional fibres by hand is very labour intensive.
