1. Ballistic Efficiency of Multilayered Armor Systems with Sisal Fiber Polyester Composites
The urban violence and the different types of global armed conflicts demand efficient protective systems against high energy ammunition. Multilayered Armor Systems (MAS) provide efficient protection by making use of lighter and more efficient materials. A typical MAS may be composed of three layers: a front ceramic followed by a composite, backed by a ductil

3. Acúmulo de cargas elétricas em propelente sólido compósito com matriz de polibutadieno líquido hidroxilado
Composite solid propellants prepared with HTPB prepolymer - Hydroxyl Terminated Polybutadiene, AP - Ammonium Perchlorate as oxidizer and aluminum particles as an additive metal, have characteristics of high electrical resistivity. The loading process of the polymer matrix did not obtain homogeneity, resulting in clusters, mainly of metal particles. The effec

5. Adesão metal-polímero: dispositivos de medição e correlações físico-químicas
Uma maneira de quantificar a resistência da interface de materiais compósitos é medindo a tensão necessária para separar o filme do substrato. Esta tensão é frequentemente usada como um parâmetro de projeto para desenvolver estes materiais. Entretanto, muitos métodos de medição da adesão não são capazes de eliminar as falhas de coesão das falh

7. Mechanical characterization using optical fiber sensors of polyester polymer concrete made with recycled aggregates
The sustainable management of solid wastes encourages metallurgic and metal-mechanic industries to look for safety applications for their wastes, thereby attenuating the environmental impact or lowering the costs. The study herein proposes strain monitoring the recycling of foundry sand with organic pollutants, as inert, in the manufacturing process of polym

8. Fenómenos de relajación interfacial en compuestos epoxi/aluminio
Interfacial dielectric relaxation has been studying in composite materials made with epoxy resin and aluminum. Electric modulus, which has been proposed for the description of systems with relaxation process, presents advantages in comparison to the classic approach of the real and imaginary part of dielectric permittivity. In composite polymer materials, re

10. A review on the development and properties of continuous fiber/epoxy/aluminum hybrid composites for aircraft structures
Weight reduction and improved damage tolerance characteristics were the prime drivers to develop new family of materials for the aerospace/aeronautical industry. Aiming this objective, a new lightweight Fiber/Metal Laminate (FML) has been developed. The combination of metal and polymer composite laminates can create a synergistic effect on many properties. T

11. Electrochemical studies on inert filler incorporated poly (vinylidene fluoride - hexafluoropropylene) (PVDF - HFP) composite electrolytes
The ionic conductivity, thermal stability and lithium transference number have been investigated in composite polymer electrolytes (CPE) of poly(vinylidene fluoride - hexafluoropropylene) (PVDF-HFP) incorporating nano fillers of AlO[OH]n or gammaAl2O3, with LiClO4 as salt. The compatibility of the composite polymer electrolyte with lithium metal anode has al
