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

2. Study of the Influence of the Hydration Level on the Electromechanical Behavior of Nafion Based Ionomeric Polymer-metal Composites Actuators
The ionomeric electroactive polymers-metal composites (IPMC) are materials that realize bending movements in response to an electrical stimulus and can be applied to the artificial muscles development. This paper investigated the influence of the hydration level on the electromechanical behavior of Nafion based IPMC. An experimental apparatus composed by a s

5. 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

6. Biomaterials : hydroxyapatite deposition study via polymeric process on cp Ti surfaces modified by laser beam / Biomateriais : estudo da deposição de hidroxiapatita por via polimerica sobre superficies de Ti cp modificado por feixe de laser
The biomaterials area has been focused on the development of synthetic or artificial materials that have similar properties to the human bone tissue. Among the diverse alternatives, one of the most used is the metallic substrate coated with bioceramics. By this technique it is possible to combine biocompatibilty, mechanical properties and corrosion resistanc

7. 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
