3.3.-Prescaling: Processing methods and characterization tests
Plenty of formulations were designed and processed by means of 5 different processing methods: i) VA-RTM, ii) infusion, iii) prepregging, iv) cork agglomeration and v) vacuum curing process (see Figure ).
Samples were characterized in order to obtain mechanical, reaction to fire and fire resistance properties.
