Fire-resist

The following table summarized the problems appeared during the scale-up and the solutions propose for the demonstrators manufacturing.

MANUFACTURING PROCESS	PROBLEM AT THE SCALE-UP STEP	SOLUTION PROPOSED FOR THE DEMONSTRATORS
APC: glass fibre reinforced furan composite	The use of biaxial glass fibre leads to delamination problems at industrial level.	Use of chopped strand mat and roving. Not expected important changes in the reaction to fire properties due to the change of the fibre type (non combustible material).
AMORIN: cork agglomeration	Cork panels agglomerated with furan resins break because of internal pressure when pressing.	Use of standard not flame retarded cork panels in the final demonstrators.

5.-WP3 Summary. Inputs to WP6: proposed demonstrator lay out

As a final result of the WP3, a sandwich panel lay out was proposed for the final demonstrators (WP6) regarding railway and naval sectors. The lay-out is collected in Figure .

Depending on the final application the number and the thicknesses of internal cork cores and intermediate layers can vary (Figure ).

These demonstrators and their properties will be described in the corresponding work package report (WP6).
