Ultra-Light Asymmetric Photovoltaic Sandwich Structures

This work evaluated the possibility of using silicon solar cells as load-carrying elements in composite sandwich structures. Such an ultra-light multifunctional structure is a new concept enabling weight, and thus energy, to be saved in high-tech applicati ...

Influence of process pressure on local facesheet instability for ultralight sandwich structures

Yves Leterrier, Julien Rion, Samuel Stutz

The skin wrinkling phenomenon was investigated in the case of ultra-light sandwich structures with a honeycomb core manufactured by one-shot vacuum bag processing. The interplay between process pressure and compressive strength of the skin was established. ...

Ultra-light photovoltaic composite sandwich structures

Julien Rion

The ultra-light photovoltaic sandwich structure is a new multifunctional structure concept enabling weight and thus energy to be saved in high-tech solutions such as solar cars, solar planes or satellites. The novelty of this approach is to use solar cells ...

Prediction of the adhesive fillet size for skin to honeycomb core bonding in ultra-light sandwich structures

Yves Leterrier, Julien Rion

The formation of resin fillet between honeycomb core cell walls and skin in light sandwich structures was studied to gain a better understanding of the bonding process. A method was developed for tailoring the amount of adhesive between 8 and 80 g/m2. The ...
