The structure consists of millions of small sealed bubbles that are closed off from each other, hence “closed-cell”. This structure provides a robust strength to the material and also gives it some of its features such as water resistance. More on features shortly.
Often, the solid foams have lower nodal connectivity to that of the other cellular structures such as truss lattices and honeycombs, and therefore, their failure mechanism can be dominated by the bending of members. Ultimately, the low nodal connectivity and the resulting failure mechanism lead to their … See more Let us look at the types of foam or foam spray in detail.
