Carbon fiber composites are used in several industries such as, aerospace, automotive, civil engineering, sports goods and technical applications due to its low-weight, strength and stiffness. However, the technology of ...

The main objective of this investigation was to study the properties of composites of polypropylene (PP) containing different proportions (20, 40 and 60% wt%) of coir short fiber (natural vegetable fiber) without treatment ...

Recently, piezoelectric cellular polypropylene (PP) was proposed as a new type of quasi-ferroelectric. The observed hysteresis of the charge density as a function of the electric field could be explained as field-dependent ...

Yellow Beryl was obtained from Teófilolo Othoni, state of Minas Gerais, and added into a matrix of Polipropileno (PP) made by Braskem. Here we have investigated the property of optical absorption (OA) of this composite ...

The large use of plastics in the world generates a large amount of waste which persists around 200 years in the environment. To minimize this effect is important to search some new polymer materials: the blends of biodegradable ...

Polypropylene (PP) samples were treated by Dielectric Barrier Discharge (DBD) in order to modify their surface characteristics. The XPS analysis reveals that the DBD treatment added oxygen atoms to the PP surface. These ...

This work concerns the study of the mechanical and thermal behavior of the polypropylene nanocomposite (NCPP) with bentonite clay Brazilian Paraiba (PB), which is known as ‘‘chocolate’’. A Brazilian polycationic bentonite ...
