There are many factors that affect the geopolymerization process and mechanical properties such as starting material including chemicals and mineral additives, alkali activators, plasticizers, processing conditions that usually time and temperature used.
The curing temperature is also considered as the factor when researching compressive properties of geopolymer matrix.
Finding out the curing temperature at which we can achieve the best mechanical properties of fly ash-based geopolymer matrix and unidirectional glass fiber are the main targets of this project.
In order to determine the mechanical properties, the samples were prepared and tested for compressive properties.
This is may be caused by sintering factor that the reaction during the process was changing of sample properties from polymer to ceramic.

Finally, the optical properties such as focal length of developed micro-lens will be measured and tested.
To discuss above described parameters that will affect the micro-lens forming mechanism.
The reason to select PMMA as micro-lens material is that the material is very suitable for optical devices because of physical properties, optical properties and ability for IR coating.
AZ4620 will show colloid property when the temperature above Tg.
The reflow process affects the photoresist column shape, thus we discuss the reflowed diameter under various heating temperature and reflow period .In this study, the micro-lens array with high fill-factor have been fabricated, it can improve the brightness and diffuseness.

An answer is to create adhesive joints with properties gradient by using the nanostructuration.
To reach this objective, we propose an evolution of the Multi Adhesive Joints (MAJ): an adhesive joint presenting a gradient of mechanical properties.
In a first part, the morphological, mechanical and thermomechanical properties of the nanostructured thermosets versus time are performed.
Therefore, by combination of LTA peeling properties with HTA’ mechanical and adhesive properties, it would be able to formulate a joint with a mechanical properties gradient.

The physical properties of the waste were compared with the real municipal solid waste (MSW).
For example, Jessberger et al. assessed the mechanical properties of waste materials in centrifuge using real MSW [2].
Physical Properties of Model Waste An ideal model waste should match the physical, chemical, and dynamic properties exhibited by the real MSW.
The main physical properties of MSW considered here are unit weight, void ratio, compression factor, shear strength and permeability coefficient.
The shear strength of municipal solid waste depends on many factors, such as its constituents, the mode of placement, and the age.

Trials show the high properties of self-centering and of wide hysteretic behavior of the RCW.
Numerical analyses confirm the mechanical properties and provide parameters to the evaluation of cyclic dissipation properties.
Once cracked, the layer of mortar shows interesting dissipative properties and still allows the self-centering when the stresses stop, because of the persistence in the elastic range of the vertical bars.
The tests show that the reduction of bearing capacity of the mortar layer of the base does not affect the functioning of the RCW: high mechanical properties of mortar should be avoided, to ensure the first cracking at the base of the building, in order to protect the overlying masonry structures.

Alumina particles attached to the resin prevent the crack growth, enhance thermal and mechanical properties, raise the glass transition temperature, and tend to increase the flexural strength and storage module.
After the tests, parameters optimizing the decomposition temperature properties are identified.
Through the study of quality characteristics response tables and graphs, and the analysis of variances, this research seeks the optimal combination of factor levels that affect the material properties.
The last column Significant identifies factors with over 95% confidence level as the significant factors.
The thermal decomposition temperature characteristics are investigated to find the significant factors of the epoxy resin under thermal property For the epoxy resin samples, the optimal combination of factors of the thermal decomposition temperature is 2wt.% Al2O3, 2wt.% SiO2 and 1.93wt.% diluent.

This requires a multidisciplinary approach and broad knowledge of disciplines spanning from biology and plant anatomy to mechanical properties and statistics.
The method can be used to detect interior defects or deterioration of wood and is used to make inferences on mechanical properties.
Since the dielectric constant of wood depends, among other factors, on wood density and moisture contents (given constant temperature and frequency), these two quantities must be measured or estimated and their variation will affect the GPR measurements.

The comprehensive mechanical properties of PM Ti2AlNb alloys are comparable to those of cast and wrought Ti2AlNb alloys [4-5].
In the EIGA process powder size may be influenced by several factors including the type of atomizing gas and gas pressure.
To ensure good mechanical properties of the compact, however, porosity inherent in the gas atomized powders must be minimized.

The understanding of the processing parameters of these composites is essential for the development of polymeric composites with superior properties [11].
Thus, the effects of processing parameters of extruded composite materials interfere with the physical-mechanical properties of these materials and, consequently, on the final performance of obtained product [10].
In this screw configuration, a wood flour may start its thermal degradation process, which could result in a decrease of the composite properties.
Such factors are proportional to the speed and depend significantly on the screw geometry and free volume [17].
This property depends on two factors, viscosity, and gradient velocity [21].

However, strong acids can also degrade polymer mechanical properties, necessitating careful selection of modification strategies [20].
More homogeneous dispersion may lead to uniform dissolution during acid exposure, ultimately affecting the material's stability and performance.
This observation indicates that while OA altered the surface properties of CC, it did not significantly affect the crystalline structures of the composite materials [39].
