1. Optimal Placement of Piezoelectric Macro Fiber Composite Patches on Composite Plates for Vibration Suppression
AbstractThis work presents a new methodology for the parametric optimization of piezoelectric actuators installed in laminated composite structures, with the objective of controlling structural vibrations. Problem formulation is the optimum location of a Macro Fiber Composite (MFC) actuator patch by means the maximization of the controllability index. The co

2. Desenvolvimento de uma metodologia computacional para determinar coeficientes efetivos de compósitos inteligentes / Development of a computational methodology for determining effective coefficients of the smart composites
O presente trabalho visa empregar uma metodologia numérica para determinar as propriedades macro mecânica de compósitos ativos (AFC - Active Fiber Composite ou MFC - Macro Fiber Composite), combinando o conceito de Volume Elementar Representativo (VER) com o Método dos Elementos Finitos (MEF). Inicialmente, apresenta-se a fundamentação teórica associa

3. Influência da nanoargila no envelhecimento higrotérmico de compósitos de polipropileno / PP maleado / fibra de vidro / Influence of nanoclay on the hygrothermal ageing of polypropylene / maleated pp / glass fiber composites abstract
In short glass fiber (GF) reinforced polypropylene (PP) composites, despite of the chemically inert and non-polar nature of the matrix, the fiber-matrix interfacial integrity may be compromised in a hygrothermal active environment by the addition of maleic anhydride (MAH) molecules of the interfacial compatibilizer (PP-g-MAH). The use of organophilic nanocla

4. Thermographic inspection of impact damage in solid fiber-reinforced polymer matrix composite laminates. / Inspeção termográfica de danos por impacto em laminados compósitos sólidos de matriz polimérica reforçada com fibras de carbono.
Continuous carbon fiber-reinforced thermosetting and thermoplastic composite laminates were exposed to single transversal impact with different energy levels. The damages marked to the structural materials were evaluated by active infrared thermography in transmission mode. In general, the thermoplastic laminate thermograms showed more clear and delineated d
