1. Nondestructive characterization of epoxy matrix composites reinforced with Luffa lignocellulosic fibers
ABSTRACT Luffa Cylindrica is a tropical plant from the Cucurbitaceae family, whose fruit becomes very fibrous when fully ripened. The lignocellulosic sponges of Luffa can be suitable for use as reinforcement of epoxy matrix composites, because they have a morphology with spatial 3-D arrangement as well as are eco-friendly materials (biodegradable, and high a

2. Influence of different catilever extensions and glass or polyamaramid reinforcement fibers on fracture strength of implant-supported temporary
In long-term oral rehabilitation treatments, resistance of provisional crowns is a very important factor, especially in cases of an extensive edentulous distal space. The aim of this laboratorial study was to evaluate an acrylic resin cantilever-type prosthesis regarding the flexural strength of its in-balance portion as a function of its extension variation

3. Analytical and experimental analysis of bond behavior between concrete and GFRP bars / Análise teórica e experimental do comportamento da aderência entre o concreto e barras de fibra de vidro impregnada por polímero
The use of new materials in civil construction combined with high technology processes leads to improvements in many aspects, like cost reductions and better structural behavior. Recently, due to corrosion of the steel bars, among other factors, many researchers have been suggesting the use of non-metallic bars as a substitution of the steel reinforcement in

4. Contribuição à inspeção, diagnóstico e procedimento de reabilitação de poste de concreto armado centrifugado utilizado em telefonia celular. / Contribution to the inspection, diagnosis and rehabilitation procedure of centrifugally cast concrete post used in telecomunication market.
Precast reinforced concrete posts were installed in Brazil by mobile telephone companies when implanting and enlarging service areas of the system starting in 1996. The great majority of these posts were manufactured by a single company, using a centrifugal process. Approximately two thousand units of posts were produced of heights ranging between 20m [60 ft

5. Análise teórica e experimental de vigas de concreto armadas com barras não metálicas de GFRP / Theoretical and experimental analysis of beams reinforced with non metallic GFRP bars
Steel reinforcement replacement aims an increase at the durability of structures with corrosion and electrical magnetic problems. But, inserting a new material at the civil construction industry demands specifications of its composition, behavior and procedures for its utilization. This work is a flexural behavior analysis of reinforced concrete beams reinfo

7. Estudo de um composito de matriz de aluminio reforçado copm fibras de AL/AL IND.2 O IND.3 obtido pela reação entre o aluminio e fibras silicosas
This investigation describes the research for obtaining metallic composites with fibrous ceramic reinforcement into an aluminum matrix, through the variation of the technique known as Reactive Infiltratíon. The fibers were incorporated into the aluminum matrix by using cold uniaxiai pressing or hot extruding processes of a mixture of aluminum particles and
