Evaluation of oat-reinforced polypropylene composite properties [Avalia??o das propriedades de compósitos de polipropileno refor?ados com casca de aveia]

摘要

The preparation of oat-reinforced polypropylene nanocomposites with different fiber contents by means of melt-processing was investigated. Composite properties were evaluated by Scanning Electron Microscopy (SEM), Flexural Modulus, Dynamic Mechanical Analysis (DMA), Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA). Findings confirmed that the oat composite properties were affected by fiber type and content. Improvements in mechanical properties were obtained using fiber contents ≤ 20% w.t.
