Abstract:In this study a composite (re)design of a sensor module on top of a marine vessel has been made. This design has been analysed with finite element software for multiple occurring load cases. Different materials have been analysed in a material study and it was concluded that an intermediate modulus carbon fibre in an epoxy matrix was preferred for the module when used as a prepreg. By combining this with an aluminium honeycomb a stiff sandwich structure is made. This sandwich also acts as a thermal insulation and electromagnetic shielding material. To meet the strict stiffness requirements different stiffener methods are analysed and a double deck concept has been chosen. By tuning the lay-up of these decks an adequately stiff structure is obtained. The joint loads are analysed and based on this analysis adhesive joints seem viable. For all external bonds electromagnetic shielding concepts are proposed. A manufacturing method for the structure is proposed as well as assembly methods.
