“…Taking into account these examples and many others available in composite manufacturing and design industry [11], it is fair to say that for helicopter tail rotor blades, the main choice regarding the construction of their inner core is comprised of polymer foams.…”

Determining the dynamic properties in the frequency domain of aircraft structural elements is a very important aspect taken into account nowadays by aircraft manufacturers. One of the helicopters most exposed element to structural vibrations is the rotor blade, thus making its construction and the material choice a very important decision. Finite element methods can be used to assess the vibrational properties of such elements, in order to prove their airworthiness. The main objective of the article is to study how the use of different materials affects the structural behavior of the helicopter tail rotor blade, with regard to the frequencies at which these structures are prone to vibrate. The blade profile is the NACA0012 symmetric airfoil used on the IAR330 helicopter tail rotor blade and the main objective is to identify the best inner core material, while highlighting the importance of polymeric materials.

“…Thus, the samples were subjected to a grindling and polishing process. These were analyzed from the point of view of the physico-mechanical and tribological characteristics, taking samples of each produced composite material in accordance with the standards in force [1,[13][14][15][16][17][18][19][20][21][22][23].…”

The brake pads are one of the basic components for the development an ecological transport. The main objective of the paper is to produce green brake pads used shells as filler material capable to reducing the emission of fine and ultrafine particles resulting from vehicle braking systems. The stages in the development of this goal were: establishing the chemical composition of shells, formulating the recipes of composite materials, selecting parameters of technology, obtaining in laboratory and characterization of new materials in terms of physico-mechanical and tribological characteristics, evaluating their performance compared to similar materials presented in the scientific literature.

This paper presents the dynamic behaviour of a race car body impacting a rigid barrier. The amount of deformation in the front bumper area and its effect on the driver's seat are investigated. The car crash is studied at different impact angles of 0 • , 10 • , 30 • , 45 • , 60 • and 80 • . The generated elastic and plastic stress and strain fields, specifically at the front bumper and the frontal area of the driver's seat, are compared accurately. Comparing the amount of deformation in different situations shows that an increase in the angle of impact results in more plastic deformation in the bumper but less on the driver's seat instead. As the bumper neutralises the effect of the largest part of kinetic energy and inertia forces, the frontal part of car body behind the bumper is safer.
