Post-fire mechanical properties of marine sandwich composite materials
Naval industry Sandwich composite materials :
- Thin skin reinforced with fibers
- Core constituted with light components
Walls andreinforcing elements
Durability of this type of materials subjected to a marine environment ?
Hygro-Thermo-Mechanical durability of composite materials
Fire resistance
Mechanical deformation
Moisture diffusion
OBJECTIVESOBJECTIVES
- Evaluation of the fire resistance of sandwich pannels
- Determination of the residual strength as a function of combustion timeand moisture rate
