This study investigates the possibility to recycle basic thermoplastics and its effect on the mechanical properties of the recycled materials.
Kristiawan et al., 2121 [8] investigated the factors that affect 3D printing results using the FDM process by determining FDM parameters and their effects and interaction with other parameters.
However, it has been well documented in the literature that recycled pellets have low and inconsistent mechanical properties resulting in a cheaper recycled products [12].
Mechanical properties of the printed parts are determined. 9.
These properties include their fire resistance, acoustics properties, durability, water absorption, heat insulation, and thermal properties.

There are two goals of the technology: 1) to obtain the correct shape of the rings, 2) to achieve required properties.
The adopted model took into account the change of the relative density of the material, affecting the closing of internal defects in the form of voids.
Extremely important parameters affecting the penetration of the deformation into the forged element are, among others: the width of the tools and the relative feed (calculated as the ratio of the forgings shift after each given deformation and the distance between the tools at the moment of starting the deformation).
This type of mesh is used to solve the mechanical problem.
In the case of upsetting the Q factor reaches the value 1 (complete closure of the discontinuities) in the zone of the greatest deformation.

This is especially true for rotor craft, where weight is a critical design factor [10].
At the boundary of the nugget zone there was the thermomechanical affected zone (TMAZ), see figure 6 b.
To enhance the precision of the numerical model, a layered type of element needs to be used, even if the assignment of the material properties among different layers is not trivial.

The microscale effect is beneficial to accurate grasp of all kinds of microscale effect in the forming reasonable classification and evaluation.Change law of microscale affects the nature of knowledge for the right team which provides effective quantitative data, when determine the major hours of rights, it also can provide the guiding idea for material selection and process optimization.The reasonable classification and evaluation of microscale effect is the experience that conventional forming calculation provides a reality way.
All aspects is spreaded to the whole process system miniaturization,. material party and the influence of the main table.Now the flow stress in the process of forming, anisotropy, forming limit and crystal materials of body scale and products relate the size: tiny structures to further spread to the influence of concrete material process,such as the forming force, friction and precision of the springback, burr and products are different with conventional scale , the micro forming process of friction lubrication conditions change, macroscopic in tribology friction theory control method is no longer applicable, the ratio of surface area and volume increase due to a microscopic scale bigger, the influence of friction on the forming is bigger than under macro dimensions, accordingly, lubrication has become a very important factors in the process, lubrication mechanism and macro situation is no longer the same.
Pultrusion products in the fiber content can be as high as 80%, rubber can give full play to the role of the reinforced material under the tension,, the product has high strength; Longitudinal and transverse strength of products can be arbitrary adjusted, can satisfy the use requirement of different mechanical properties of products.No marginal waste appear in production process, product does not need after processing, it saves work , raw materials and energy than other processes, Product quality is stable, good repeatability..

The contributions of these elements to the buildings' energy efficiency due to the thermal mass properties are important.
· Cool Roof - A Cool Roof is a system that reflects the solar heat due to the reflective and emissive materials' properties.
Table 8 presents the properties of the materials.
Table 9 presents the properties of the materials.
Thermal comfort depends on different aspects, such as air temperature, humidity, movement of air, thermal radiation - environmental factors, and physical activity and clothing - personal factors).

Introduction The FRP re-bars are gaining broad acceptance in the construction industries due to their superior physical and mechanical properties.
Mechanical Properties of Materials FRP Re-bars.
In the table mechanical properties of steel re-bar are also included for comparison purposes.
The required properties of polymer mortar are high strength, good bond strength, workability, etc.
Therefore, it can be said that the beam designed by this approach may have at least more than 11% reserved moment strength without consideration of load and strength reduction factors.

Since meat putrefaction is a complex process that is influenced by many factors, it is necessary to have a comprehensive investigation of the various indicators to determine the freshness of meat.
Arguably, the methods above have only consider single factor (elasticity or odor etc.) for the detection the freshness of meat.
However, because meat rotten is a complex process that is influenced by many factors, therefore, we should integrate various indicators to determine the freshness of meat.
Based on research of different types of MOS gas sensor and properties of volatile gas in the process of storage chicken, the MOS gas sensor of TGS series were selected: TGS2600, TGS2602, TGS2610, TGS2611, TGS2620 and TGS2442 models.
Adequate selection of sensor and proper combination of array, will directly affect the performance of the electronic nose system.

Weld quality is greatly influenced by the weld parameters which directly or indirectly affect the response parameters.
For all the mechanical properties of the welded joint higher- the- better criterion have been selected.
From table(2 ), it has been seen that for some factor combinations the over desirability become zero.

The interaction is determined by the material characteristics and the main factor is the susceptibility to absorption of microwaves.
The properties of the base materials, determined by mechanical testing just before the microwave heating are presented in Table 1 and Figure 3.

Factors such as humidity and the presence of hard particles in the air can influence the tribological processes and indirectly affect the braking effectiveness.
These difficult to control factors, i.e. hard particles and water, are often present and represent the serious tribological problems during braking operation [4].
The transfer film mediates the interaction between the mating surfaces and changes the tribological properties at the sliding interface significantly [9].
