The production of composite materials through the reuse of waste or by-products from the agri-food industry will be a challenge for environmental protection. This study focuses in that direction. In the first stage, composites were made with the hybr

This paper presents studies on the dynamic analysis of the ASPIRE robot, which was designed for the medical recovery of brachial monoparesis. It starts from the virtual model of the existing version of the ASPIRE robot, which is analysed kinematicall

In this paper, we have built some composite bars with the reinforcement made by fiber glass which is randomly disposed and the matrix made by ambresit. Then, in order to study the samples free vibrations, we have clamped the bars at one end and we

In this paper, I have built a composite sample made from glass fiber as reinforcement and Aropol as matrix. For this sample, I have used an experimental procedure to determine the damping properties and the frequency of the first eigenmode. The exp

The paper generalizes the Timoshenko model for thick bars, using a new model that is applied to the vibration study of multilayer composite bars. In the proposed mathematical model, three coefficients are introduced that take into account the non-uni

At the moment, the tendency in the composites field, is to use natural resins and fibers to obtain �environmental friendly� materials, that are compostable and biodegradable. In this paper there is an experimental study of the depletion capacity

In this paper we present some researches about the static mechanical properties for some composites made in this way: the reinforcement is made from two types of felt and the matrix is from epoxy resin Resoltech 1050 with its hardener Resoltech 1055.

This paper studies the influence of the volume proportion between components on the mechanical behaviour of a hybrid resin obtained by combining the natural resin Dammar and epoxy resin. We analyse three sets of hybrid resin samples, in which we used
