Hong et al. [5] found that there was a linear relationship between the delamination area and impact
energy of the projectile through impact tests using glass/epoxy laminates and small steel projectiles.
Morita et al. [6] showed that this delamination area was also linear to the impact energy in lowvelocity and high-velocity tests.
The results were as follows: EL = 114 GPa, ET = 8.3 GPa, GLT = 4.1 GPa and νLT = 0.32, where E, G, and ν are the longitudinal, transverse moduli, and Poisson's ratio, and the subscripts L and T denote the longitudinal and transverse-to-the-fiber directions, respectively.

Abstract.
After the growth of the SiC layer, an ohmic contact layer of Al (thickness of 0.5 µm) was deposited by thermal evaporation on the sample backside.
In order to facilitate the electrochemical etching of the substrate, a thin metallic film of aluminium (Al) was deposited onto a SiC layer prior to anodization.
The rear contact was realized by deposition of thin aluminium (Al) layer.
This phenomenon indicates clearly the role of the PSC layer thickness on the electrical parameter of the Schottky diode. 0.0 0.2 0.4 0.6 0.8 1.0 1.2 0 20 40 60 80 100 UDTS/CMA12-Pd/PSC10 50 % at 0.6 Volt Schottky Diode : Pd / PSC(0.16 SiC) / p-Si(100) / Al Sensivity ∆∆∆∆I/I [%] Forward Bias Voltage [V] 0,0 0,2 0,4 0,6 0,8 1,0 1,2 0 20 40 60 80 100 UDTS/CMA12-Pd/PSC9 66 % at 0.5 Volt Schottky Diode : Pd / PSC(1.6 SiC) / p-Si(100) / Al Sensitivity ∆∆∆∆I/I [%] Forward Bias Voltage [V] Fig. 5, Sensitivity vs. bias voltage of C2H6 gas at room temperature ambiance for 0.16 µm SiC (a) and 1.6 µm SiC (b) with porous SiC structure Table 2: Barrier height and series resistance variation of the sensor compared to air Pd/PSC(0,16µmSiC)/p-Si/Al ∆∆∆∆φφφφBp (meV) = φφφφBp(air) - φφφφBp(gas) ∆∆∆∆RS (Ω) = RS(air) - RS(gas) C2H6 gas - 7.6 - 2 Pd/PSC(1.6µmSiC)/p-Si/Al ∆∆∆∆φBp (meV) = φφφφBp(air

Experimental
The fabrication process of the functionally graded aluminium matrix composites was carried out in a
high frequency induction centrifugal casting furnace as described by Gomes el al. [1,2,4].
These reinforcing particles, possessing high hardness, can protect the Al matrix from extreme wear damage.
The concentration of released Al, dissolved in the electrolyte after the sliding test, is showed in Fig.3.
As it can be seen, the composite containing a lower amount of reinforcing particles is the one giving origin to a greater release of Al.
Conversely, an increase in the amount of particles results in a lower quantity of Al being dissolved in the solution.
