1. Foam structure vs. lightweight structure
1.1 MD / HD lightened structure
If we combine 200 cm 3 of air and 800 cm 3 of polystyrene PS in a box (figure 1 -a), we obtain a mixture of 1,000 cm 3 with a weight of 840.56 g (air: 2.8 g/1,000 cm 3 and PS: 1,050 g/1,000 cm 3 ). In other words, a new material with a density of 0.84 g/cm 3 has been created, whose structure corresponds to that of a 1,000 cm 3 box enclosing a 200...
