As such composite materials are usually more expensive and less recyclable/degradable than the original biosourced polymer, their commercial use must be avoided.

It belongs to the thermal theory of natural science.
According to some data, the value of materials commonly used in building is about 0.7W/(m*K).
The first is the use of long and short-foam construction materials.
Secondly, we can use hollow bricks and aerated concrete materials to reduce thermal conductivity.

Introduction All kinds of different brittle materials such as ceramics, functional material are used widely in aeronautics, waterdipper and auto-mobile etc fields.
The failures of materials can be classified into two types: brittle fracture and plastic deformation according to the classical strength theory of which the former is affected mainly by traction stress and the latter is deviator strain energy density.
