Informes: "Steel fibers. eng" – Grafiati

Entretanto, observa-se que, quanto menor o vão maior a influência das fibras, sendo esse acréscimo de 35 porcento para o vão de 300 mm, 30 porcento para o vão de 500 mm e 24 porcento para o vão de 800 mm. O maior consumo de fibras conferiu à matriz maior resistência à flexão e ao cisalhamento, mostrando sempre maior influência para ...

Structural Evolution of Polyacrylonitrile Fibers in ...

The effect of structural evolution polyacrylonitrile (PAN) on mechanical properties was investigated in stabilization and carbonization. PAN spun fibers were stabilized in a convection oven with a constant tension for various times at 250℃. Fourier Transform Infrared spectroscopy (FTIR) and gel fraction results suggested that intra and intermolecular stabilization reactions occurred ...
