Al-7075-T6) useful in the aerospace and automobile industries [1].
The study on the effects of FPL pre-treatment of Al substrates prior to the adsorption of bis-1,2-(triethoxysilyl) ethane (BTSE) showed that the formation of Al-O-Si covalent bond and the increased roughness leading to increased physisorbed silane in surface crevices are the two major contributing factors to the high bonding strength [4].

The analysis of experimental data concerning wetting of ZrB2 by different molten metals, such as Cu, Al, Ga, In, Ge, Sn, Ag, Fe, Ni and Co showed mainly non wetting behavior with contact angle variations from 103 to 135° [1,2,7].
As concerns the wetting of ZrB2 by Ag-Cu, Ag-Zr and Ag-Cu-Zr molten alloys, some results were recently reported by Muolo et al. [8].

The effect of the fibre compression on the composites made from kenaf and bamboo fibres and biodegradable resin were investigated by Shibata, et al [1].
Flexural properties of kenaf unsaturated polyester composites have been reported by Ishak et al [5] and the overall results shows that the optimum fiber content was 10 wt%.
A selection of four different polyester resins have been used for kenaf fibers composites as Aziz et al [6] reported for different volume fractions.
