The effect of alkalization on the mechanical and physical properties of the composites were determined.
From the results, increase in fiber content and alkali treatment of the fibers improved the mechanical properties of BPC.
The other factors that contribute to the use of alternative materials to wood was that Malaysia is facing ecological issues as there were abundance of agricultural waste.
This leads to poor mechanical properties of the composite when used as structural material.

Microstructure and Mechanical Properties of Dissimilar Ferritic and Austenitic Steel Joints with an Intermediate Inconel-182 Buttering Layer A.M.
Mechanical tests show that the average hardness, tensile ductility and impact energy of the weld metal were enhanced with increasing width of the buttering, while tensile strength properties were unaffected.
Residual stresses, brittle phase formation, dilution and carbon migration from the HAZ region on the ferritic steel joint are among the factors which weaken the HAZ region [1,3,4].
Tensile properties.
The results show that the Inconel-182 buttering layer employed in the dissimilar weld joints enhances the final elongation of the weld metal without affecting its yield and tensile strength.

%Ce; (c) extruded without Ce; (d) extruded with 0.25wt.% Ce Mechanical properties.
Two opposite factors affected the mechanical properties of brass together.
When the content of Ce was lower than 0.10wt.%, promoting hard phase precipitation played a dominant factor and led the mechanical properties of brass decreased with the increasing content of Ce.
When the content of Ce exceeded 0.10wt.%, refining grain played a dominant factor, and thus the mechanical properties increased with the increasing content of Ce.
In conclusion, the addition of Ce failed to improve the mechanical properties.

The research shows that the water absorption effect of brick powder and the friction force are the two main factors affecting concrete.

The influence of the mechanical property of the inclusion and the distance to the crack tip was examined.
From the above, all test specimens are not affected by mode �.
From these results, the stress intensity factors of cracks on the inner side of inclusions are generally greater.

The improvement of mechanical properties of AlN/BN composite ceramics is due to the fine and homogenous microstructure developed in the SPS process.
Hardness, thermal conductivity and mechanical property.
It could be assumed that sintering method as well as characteristics of h-BN was the significant factor affecting the microstructure and properties of AlN/BN composite.
Compared with the samples sintered by conventional sintering processes, AlN/BN samples sintered by SPS exhibit better mechanical properties.

However, actual applications of pure polypropylene are limited due to the poor mechanical properties during service life.
Effects of experimental factors on the weldline tensile strength were plotted on Fig. 4(d).
The most significant factor affecting weldline tensile strength was gate locations, followed by injection pressure, melt temperature and injection speed.
The most significant factor affecting weldline strength was gate locations rather than process parameters.
Experiments carried out in this study revealed the significance of gating system design on the weldline mechanical properties.
