This study aimed to trace the best prepared composites material to the unmanned aerial vehicles (UAVs)
real sample. Carbon composite materials have extraordinary material properties in UAVs manufacturing.
In this work, vacuum bag technique is used to prepare rectangular strips of four different carbon fiber
composites densities. Spectroscopic characterization and investigating their dynamic mechanical properties
have been deployed on them.
Fourier transform infrared (FT-IR), energy dispersive X-ray (EDX), and laser induced breakdown
spectroscopy (LIBS) techniques were used. The FTIR spectrum of carbon fiber exhibited multiple bands in
the region between 1500 and 1000 cm
1 related to stretching vibration of CeO bond from carbonyl
functional groups and CeC bond in aromatic rings due to the presence of aromatic molecules in the
epoxy resin in the structure of carbon fiber. EDX and LIBS techniques revealed the quantitative and
qualitative characteristics of the main constituted elements of prepared fiber. The dynamic mechanical
properties were measured under cyclic uniaxial tensile loading at different frequencies where activation
energy was calculated. Finally, the results were then compared to the measurements obtained from real
UAVs material.
