Investigation of toughening mechanisms in elastomeric polycarbonate blends thro...
Rodrigues, Pedro António Veiga; Ramoa, Bruno; Castro, Maria Cidália Rodrigues; Machado, A. V.Despite polycarbonate (PC) being a widely used engineering plastic, its notch and crack sensitivity pose challenges in critical applications. To address this, PC was blended with elastomeric polymers to explore the improvement in toughness. This study systematically investigates the toughening mechanisms of PC blended with acrylonitrile–butadiene–styrene (ABS), copolyether ester elastomer (COPE), and ABS and st...
Assessing the compressive and impact behavior of plastic safety toe caps throug...
Rodrigues, Pedro Veiga; Ramoa, Bruno; Machado, A. V.; Cardiff, Philip; Nóbrega, J. M.Toe caps are one of the most important components in safety footwear, but have a significant contribution to the weight of the shoe. Efforts have been made to replace steel toe caps by polymeric ones, since they are lighter, insulated and insensitive to magnetic fields. Nevertheless, polymeric solutions require larger volumes, which has a negative impact on the shoe’s aesthetics. Therefore, safety footwear manu...
