Abstract.
The basic mechanical properties and penetration performance of a new type of fiber concrete reinforced by UHMWPE fiber were experimental investigated.
The influences of fiber addition, forms at fiber ends, fiber dimensions and other factors on anti-penetration performance and mechanism of the SFRC are investigated [5-7].
Ultra high molecular weight polyethylene (UHMWPE) is a new kind of ballistic fiber [9] which has excellent properties of impact-resistance.
Mechanical Properties Primary materials and Mix design of concrete.

It was hypothesised that the mechanical
properties would be linked to the shape of the pore structure due to the orientation of the open
porous scaffolds (OPS) produced.
Factors such as porosity, biocompatibility and structural integrity are of critical importance in the development of bioactive calcium phosphates [5, 6].
Figure 3 gives a summary of the mechanical properties for the OPS produced.
The mechanical properties of the samples produced were found to be low.
Elongating the pore structure in transverse and longitudinal directions did not affect the total porosity of the bioceramics or their mechanical properties.

Asphalt aging is a pivotal factor affecting the service performance of asphalt pavement.
Introduction Asphalt aging is a crucial factor affecting the service performance of asphalt pavement.
In the aging process, a series of physical and mechanical properties of asphalt will change, which has been studied by standard test methods for many years.
This experiment studied the influence of ultraviolet rays on asphalt composition, structure and properties.
(4) Ultraviolet aging obviously affects the rheological properties of asphalt at low temperature, which shows that the composite modulus increases and the phase angle decreases.

The continuous development of steel products requires the detailed investigation of
relationships between the production technology, microstructure, and mechanical properties.
That is why it is not surprising that several scientists aim to evaluate the relationship between the microstructure and mechanical properties of the thermomechanically rolled steels [4,5].
In order to investigate further the relationship between the microstructure and the mechanical properties and to separate the effects of the different microstructural parameters, a correlation analysis was carried out.
This means that the morphological anisotropy of the steel strips produced by controlled temperature rolling has a significant effect on their mechanical properties.
The method of the controlled temperature rolling has a significant effect on the nature of the relationship between the microstructure and the mechanical properties of the steel strips.

Even though, there are some molding factors which could affect products quality.
These factors represent potential sources of variability in the analysis system.
The observed mechanical properties are explained in terms of fiber orientation.
Especially, the buckling of neat PBT is not clear affected by those process factors at all.

Processing Defects and Nanoindentation Mechanical Properties
in Tape Cast Alumina/Zirconia/Mullite Layered Composites
S.Y.
Therefore, any residual stress remaining in the adjacent layers will be an important factor governing the mechanical properties of layered composite.
In such a case, the magnitude of residual stress would decrease gradually away from interlayer, with a similar tendency for the mechanical properties.
Even though the higher residual stress in the A/YZ(2) compared to the A/YZ(1) region, the mechanical properties in the A/YZ(2) region were low.
Summary The mechanical properties determined by nanoindentation are strongly affected by the presence of processing cracks in the sintered alumina/zirconia/mullite symmetrically layered composites.
