“…The simultaneous increase in tensile strength and strain% at 60 wt% of fibres compared to other ratios was the sign of higher impact toughness. The tensile results are in accord with the work of Rahmani et al (2014) and Cai et al (2016).…”

Lightweight and high strength composite materials are vital for unmanned aerial vehicles (UAVs) and aerospace technologies with desired characteristics. Carbon composite materials exhibit extraordinary properties for UAVs and aerospace applications. This study aimed to discover the best-prepared composition of composites material having epoxy LY-5052 and carbon fibres laminate for UAVs. Besides, to develop a low cost with high specific strength composite material for aerospace application to replace metallic alloys. In this work, the vacuum bag technique is used to prepare rectangular strips of three different ratios of carbon fibre/epoxy laminates [(40:60), (50:50) and (60:40)] to obtain the best composite in terms of properties. The thermo-mechanical and viscoelastic behaviour of composite materials were evaluated using differential scanning calorimetry (DSC), universal testing machine (UTM) and dynamic mechanical analysis (DMA). The tensile strength of epoxy LY5052 composites with 60 wt% has enhanced to 986%, and glass transition temperature (Tg) was improved from 71oC to 110oC. Overall, 60 wt% carbon fibre exhibits better thermo-mechanical properties with lightweight, which may be a future composite material for aerospace, especially UAVs technologies.

“…Uniaxial tension tests were performed using an MTS testing system, equipped with hydraulic grips; a computer with a control system was connected to it for data acquisition. Biaxial tension tests were carried out on a SDS100 electro-hydraulic servo biaxial testing machine, with a capacity of ±100 kN for each of its two orthogonal directions with four independent servo-hydraulic cylinders [31].…”

An experimental study was focused on investigation of the failure properties of plain woven glass/epoxy composites under offaxis and biaxial tension loading conditions. Four fibre orientations (0 ,15 ,30 and 45 with respect to the load direction) were considered for off-axis tests and two biaxial load ratios for biaxial tests to study failure characteristics and mechanism. Four classical polynomial failure criteria-Tsai-Hill, Hoffman, Tsai-Wu and Yeh-Stratton-were analysed comparatively to predict offaxis and biaxial failure strength of the composites. For failure prediction of the plain woven composites under multiaxial tension loads, the Tsai-Wu criterion was modified by introducing an interaction coefficient F 12 obtained from 45 off-axis or biaxial tension tests and the Yeh-Stratton criterion was modified with the interaction coefficient B 12 ¼ 0 or obtained from the biaxial tension test. The former criterion was found to have higher accuracy. Finally, according to macroscopic and microscopic studies, the failed specimens showed mostly distinct failure with a specific fracture orientation, mainly exhibiting fibre or fabric tensile fracture mode and a combination of matrix cracking and delamination, both in off-axis and cruciform samples.

“…The force of the sintered contact Fii increases with the particle diameter, suggesting larger sintering necks for larger particles. Assuming as a reference for the material tensile strength σtm a value of 100 MPa for glass (Cai et al, 2016) and of 600 MPa for the ceramic material (Chirone et al, 2016) it is possible to use the values of Fii to estimate the contact neck size, dci:…”
