impact toughness

The production of shredding shafts for industrial shredders presents significant challenges due to the high mechanical loads and exposure to abrasive materials these components must endure. Traditional designs involve the complex and labour-intensive process of welding sprockets to the main shaft, which increases manufacturing, labour, and maintenance costs. This study explores a novel approach to manufacturing shredding shafts by implementing cast sprockets, significantly reducing the complexity and expense associated with traditional designs.

A quantitative structural model of particulate-filled polymer composites impact toughness, based on the fractal analysis ideas, was offered. The model demonstrated good correspondence with the experimental data. It has been shown that the action of nanofiller as nucleator, resulting in crystallinity degree and amorphous phase structure change, exert the main influence on impact toughness value.
