Technological development depends mainly on the progress of materials so that materials must be able to withstand service conditions. Accordingly, we always move towards composite materials, by combining two or more materials and often have different properties, so that the two materials work together to give unique composite properties. The aim of...

This research aims to study the effect of glass fibres and aluminium nanoparticles on the mechanical properties of composite materials containing epoxy resins and phenol formaldehyde in different proportions. The results showed that adding phenol formaldehyde to epoxy in a ratio of (10/90) improved the properties, and that reinforcement with glass...

That technological development depends on progress in materials, so one has to realize that the best design for vehicles or aircraft is for materials to be able to carry the loads and conditions of the service, whatever the field, the final restriction on progress depends on materials. Composite material is composed by combining two or more substan...

Phenol-formaldehyde resin was mixed with epoxy resin in different proportions to form a hybrid mixture of composite materials. It was reinforced with carbon fibers, glass fibers, Kevlar fibers, magnesium oxide and zirconia nanoparticle particles. This research investigates the effect of fibers and nanoparticles on the behavior of hybrid composites,...

One has to realize that the best design for cars, aircraft or parts of machines is to be able to carry the loads and conditions of service, from here to the composite materials to combine two or more materials that often have completely different properties Which work together (those materials) to give unique vehicle properties, to be used in elect...
Article
Phenolic formaldehyde (resole) resin was used at a different weight (10%, 20%, 30%, 40%), with epoxy resins at varying percentages (90%, 80%, 70%, 60%) at 20 C °. In order to study the mechanical properties (which including: Tensile strength, hardness and shock resistance), for the purpose of analysis and comparison with the mechanical properties o...

... There are four basic kinds of electric polarization: Electronic polarization, ionic or atomic polarization, dipolar polarization and space charge or interface polarization. The total polarization of an arbitrary dielectric material is contributing of all kinds of polarization; as shown in figure (1) [4,5]. The polymer matrix composites classified as insulators. ...
... To analyze the engineering behavior of the prepared eggshell powder/PLA composites tensile test was performed [28]. Figure 7 and Figure 8 show the stress-strain behavior of PLA and their composites with uncalcined and calcined eggshell respectively. ...
