== Abstract ==

This abstract describes the weight optimization process followed by ALESTIS AEROSPACE in a secondary faring structure, designed and manufactured in composite material, focused in detail in the Belly Fairing structure of the A350 XWB A/C. The obective of this abstract is to enumerate and to decribe the weight optimization processes of this kind of structures, vieweing in detail following aspects:

Optimum floatability definition in the joint between panels and structure
Optimum design in sandwich panels
Method to obtain out of plane loads for the joint between sandwich panel and structure
Allowable determination for CFRP structure, based on finite element models correlated with mechanical tests

It is also described in ths abstract the process followed to obtain test allowables and the methods developed to perform the weigth optimization in panels.
Results obtained evidence that the Certification requirements are fulfilled for the complex design of a fairing such as Belly Fairing from A350XWB, manufactured with carbon fibre meterial with an optimum weigth.

 La rigidez de la unión está relacionada con la flotabilidad. Para el caso el que ambos materiales de las piezas de unión, geometría y espesores sean iguales, hay un efecto en la rigidez de la unión, como se ve en la parte lineal de las curvas de las <span id='cite-_Ref481672695'></span>[[#_Ref481672695|Figura 4]] y <span id='cite-_Ref481672696'></span>[[#_Ref481672696|Figura 5]].
