The secondary raw materials restarted in the production process can consist of at least three qualitatively different categories of materials: - with the same characteristics as the original materials - with characteristics of new materials, replacing the traditional ones in the same applications from which they originated - with characteristics of new materials, replacing traditional ones in applications other than those from which they originated The first category includes those materials which, after having been separated in the treatment phase, can be added to the virgin material at any stage of its transformation process and are no longer distinguishable from it.

Hypotheses about the Tools Origin of Textile Materials Yuan Taoa, Weidong Yu*b Key Laboratory of Textile Science & Technology, Ministry Education, Donghua University, Shanghai, China a2010taoyuan@163.com, bwdyu@dhu.edu.cn Keywords: Origin; Tools; Textile materials; Primitive man.
Performance Forms of Primitive Textile Materials Single Fiber Shaped Textile Materials.
The first hypothesis can be proposed that textile materials are firstly used as tools, that means the origin of textile materials is tools, and the origin time of textile materials is not later than stone tools.

Fig.1 Heat storage materials with expanded graphite Fig.2 Scanning electron microscope photograph of the expanded graphite After differential scanning calorimetry, the transition temperature of phase change materials with expanded graphite is 58.544 ℃, phase change enthalpy is 307.762 kJ/kg.
The transition temperature of phase change materials without expanded graphite is 63.71 ℃, and the phase change enthalpy is 311.997 kJ/kg.
The reason is that the expanded graphite has a high thermal conductivity and heat storage and release rate of the composite phase change materials is improved, in transfer process.
Phase change materials were made into a square plate, size 260 mm× 260 mm× 20 mm(Fig. 7).

On the other hand, a new process for manufacturing hybrid metallic materials is described.
These semi-finished materials consist of two different metallic materials and are both to be heated into the semi-solid state.

Introduction Composite materials make up a separate section of materials science and form their own segments of production, in some cases they form the whole industry.
The obtained materials are used for the manufacture of functional materials.
