Even though poly(lactic acid) (PLA) is fragile under impact and has low toughness, the polymer stands out for its stiffness and high tensile strength. This polymer is an interesting material not only for short-term ...

Metallic glasses alloys are a relatively new class of materials characterized by the absence of structural long-range order. During heating, these alloys exhibit a glass transition at a temperature (Tg) before reaching the ...

The oil exploitation and production in the pre-salt layers in safe, efficient and economically viable way depend on the development of materials that bear the severe conditions found in their applications during their whole ...

Blown of films is one of the most important processes of polymers for packaging application. The final properties are strongly linked with the morphology developed during the processing. The relationship between process ...

Responsible for an annual demand higher than 70 millions of tons, the poly(para- aramide) fibers are being widely used in the safety, automobilist, aeronautic, and petroleum industries, due to their attractive mechanical, ...

Using a maleic grafted polypropylene copolymer as a compatibilizing agent on a composite with hollow glass microspheres HGM is one way to reduce the mechanical properties decrement associated to the round, hollow, hydrophilic ...

Porcelain stoneware tiles, porcelanatos, present excellent technical and aesthetic characteristics. In Europe, the bodies used in the manufacture of porcelain and porcelanatos are based on the classic triaxial ceramic, ...

This work aimed to evaluate the possibility of combining spray forming processing with mechanical processing techniques (for instance, extrusion, rotary forging, and equal-channel angular pressing (ECAP)) to be used as ...

The need for materials with higher mechanical and corrosion resistance in corrosive environments, such as in oil extraction in saline media, paper and pressure vessel industry, has led to the use of stainless steel Super ...

Fossil Fuels have been used for more than a century as energy sources and vectors. Albeit their high energy densities and easy transport and containment, their availability is limited and they are notorious local pollution ...
