Thermal-Mechanical Properties of Polyurethane-Clay Shape Memory Polymer Nanocomposites [PDF]
, 2010 Shape memory nanocomposites of polyurethane (PU)-clay were fabricated by melt mixing of PU and nano-clay. Based on nano-indentation and microhardness tests, the strength of the nanocomposites increased dramatically as a function of clay content, which is

Indentation Size Effect on the Hardness of Silicon Carbide Ceramics [PDF]
Kemija u Industriji, 2010 The Vickers hardness of CVD SiC ceramics is determined as a function of the indentation load. Vickers hardness pyramid-shaped sharp diamond indenter with angle between opposite faces at an angle of 136° was used to apply five indentation loads of 4.91; 9.

Effect of Morphological Changes due to Increasing Carbon Nanoparticles Content on the Quasi-Static Mechanical Response of Epoxy Resin [PDF]
, 2018 Mechanical failure in epoxy polymer and composites leads them to commonly be referred to as inherently brittle due to the presence of polymerization-induced microcrack and microvoids, which are barriers to high-performance applications, e.g., in ...
