Caracterização Mecânica de Compósitos de Poliamida/Fibra de Carbono Via Ensaios de Cisalhamento Interlaminar e de Mecânica da Fratura

Abstract: Resumo:Compósitos termoplásticos a partir de poliamidas 6 e 6,6 e tecido de fibras de carbono com 40, 50 e 60 % em volume de reforço foram processados via moldagem por compressão a quente e caracterizados por ensaios mecânicos destrutivos (cisalhamento interlaminar em três pontos (short-beam), cisalhamento interlaminar por compressão (CST) e ensaios de mecânica da fratura) e por inspeção não-destrutiva (ultrasom e microscopias óptica e eletrônica de varredura). Os resultados obtidos mostraram que os compósitos… Show more

“…This test consists of the generation of a direct shear load along the interlaminar interface and forces the separator to break in pure shear. The distribution of the shear stress is almost uniform across the thickness with two peaks close to the edges of the loading surface [26][27][28]. To perform this test, 5 specimens with dimensions of (10 × 10 × 3) mm were used, the test speed was 0.25 mm min −1 and 10 KN load cell.…”

“…Translaminar fractures are those that occur transversely to the plane of the laminate, causing significant rupture of the fibres. Normally there are components that display the three types of fracture simultaneously [26,27].…”
