Much of the body’s native extracellular matrix is composed of natural materials like collagen, elastin, fibronectin and laminin.
Natural materials, mostly natural polymers, are cost effective, eco-friendly, have good biodegradability but they have some disadvantages (Table 4).
Composite materials generally don’t have any disadvantage as they are the combination of two or more polymers to impart various desired properties.

Many workers have investigated various die materials and forms that could be used for this purpose [10- 21].
Amorphous materials are also considerably harder and more corrosion resistant than their crystalline counterparts [29-31].

It is determined by the heat and mass transfer peculiarities in the heated layer and on the surface of these fuel materials during the local thermal effect.
The phase transfer heat means that the evaporation of any liquid fuel is essentially higher (more than in 10 times) than the heat, spent for gasification of the forest fuel materials (the thermal decomposition).
