“…An understanding of compressive properties is crucial to the development of improved composite materials and is a design limiting parameter [22]. Types of composites which are including CF reinforced PEEK and GF reinforced PP were subjected to compression loading in accordance with ASTM D 3410 standard.…”

Aerospace industry requires engineering materials with significant mechanical strength, low cost, easy to recycle, easy to process, and high chemical resistance. Thermoplastic composites are considered as new generation aerospace structural materials due to their superior characteristics. In this study, one of the most common methods used in manufacturing of thermoplastic composite parts from unidirectional (UD) pre-consolidated prepreg (blank), press forming process is investigated and crack behavior of the samples is examined. The forming process is utilized, and consolidated blanks of UD CF/PEEK and GF/PP composite materials are shaped by pressing, and mechanical tests are performed. Micro defects on the samples are monitored by microscopic examination and scanning electron microscopy (SEM) analysis. Results show that when the temperatures of CF/PEEK and GF/PP blank are increased by preheating, the formability of both composites are enhanced. Final outcomes reveal that both CF/PEEK and GF/PP composite materials can easily be used for possible aircraft structures. Additionally, CF/PEEK is found to be appropriate not only secondary structures but also for primary structures.

“… in case of static calculation, the concrete elasticity modulus is accepted with a coefficient of 1.0,  in case of seismic calculation, the concrete elasticity modulus is accepted with a coefficient of 0.75,  in the case of seismic calculation for buildings with reinforced concrete frame systems, when the allowable damage coefficient is k1 = 1, the maximum deviation value should not exceed (1/300)•H (where H is the floor height), in this case the elasticity modulus in the calculation is accepted with a coefficient of 0.75. The regulating coefficient of 0.8 for displacements by HHSHN II-6.02-2006 has not been applied,  when making calculations, it was taken into account that the magnitude of the ground subgrade coefficient -c1, varies during static and seismic calculations [11][12][13].…”

The article touches upon the comparative analysis of bearing system calculations of a multi-storey residential building with site cast reinforced concrete frame and shear wall constructed by two different methods. In the calculation models, the shear walls are constructed from site cast reinforced concrete in the first case, and from three-layer sound and thermal insulating bearing panels in the second. The calculations have been made considering the impact of the seismic force. According to the calculation results, the dynamic parameters of the bearing systems of the buildings and the economic efficiency indicators have been compared. Considering the fact that in the recent years three-layer sound and thermal insulating panels have been widely used in the world, the study attempted to reveal the efficiency of using such panels in the Republic of Armenia.

“…There has been some works in field of TPC, but it is still in the initial stage [20][21][22][23][24]. Chen et al [25][26][27] fabricated thermoplastic corrugated sandwich structures and conducted a series of studies on their quasi-static compression performance. At present, majority of studies mainly focus on the quasi-static mechanical properties of TPC sandwich structures, while the research on their dynamic properties is relatively lacking.…”

Composite corrugated sandwich structures have a wide range of applications in aerospace field, and the loss of structural load carrying capacity due to low-velocity impact damage has become one of the main threats in practical applications. In this study, the impact resistance of corrugated sandwich panels prepared from thermoplastic composites (TPC) under low-velocity impact loading was investigated. Through a series of drop-weight experiments and finite element simulations, the impact response process and damage morphology of the thermoplastic composite sandwich panels were obtained, and the effects of different impact energy and different core arrangements on the energy absorption performance of the structure were explored. Finally, a parametric analysis of the perpendicularly-arranged double-layered corrugated sandwich panel was carried out. The results show that thermoplastic composite sandwich panels exhibit an overall collapse response rather than localised damage, and the structure maintains good integrity and stability. The perpendicularly-arranged sandwich panels rely on the orthogonal configuration characteristics to provide optimum impact load carrying capacity, their impact resistance can be further improved by increasing the thickness of top face-sheet and reducing the thickness of the middle face-sheet at the same time. This provides a basis for promoting the application of TPC in engineering and the design of sandwich structures.
