2. Physical analysis of composite structure
Characterization of the physical structure of the composite material being manufactured, based on a determination of the reinforcement, filler and porosity ratios, makes it possible to monitor the consistency of a manufacturing process and, in addition, to measure the parameters required for calculating multi-layer materials.
2.1 Fiber and filler content, and reinforcement structure
In the case of glass fiber composites, a calcination test (loss-on-ignition test) at 625 ×C with sample weighing before and after oven passage (NF T 57-102 and ISO 1172) allows :
measure the mass ratio of non-volatile fillers at the test temperature, i.e. the mass ratio of glass
