Fatigue Performance and Multiscale Mechanisms of Concrete Jan 02, 2014 · For improving bending toughness and fatigue performance of brittle cement-based composites, two types of water-soluble polymers (such as dispersible latex powder and polyvinyl alcohol powder) and waste tire-rubber powders are added to concrete as admixtures. Multiscale toughening mechanisms of these additions in concretes were comprehensively investigated.

    From force-responsive molecules to - Science Advances

    Directly quantifying a spatially varying stress in soft materials is currently a great challenge. We propose a method to do that by detecting a change in visible light absorption. We incorporate a spiropyran (SP) forceactivated mechanophore cross-linker in multiple-network elastomers. The random nature of the network structure of the polymer causes a progressive activation of the SP force Polymer Toughness and Impact Resistance. - Free Online Dec 01, 1999 · At some temperature, depending on the structure and morphology of the polymer, the geometry of the specimen, and the nature and speed of the test or other energy input, a polymeric material undergoes what is known as a ductile-brittle transition. Polymers Free Full-Text Advances in Wood Composites In addition, it reviews some important aspects in the field of wood composites, with particular focus on their materials, applications, and engineering and scientific advances, including solutions inspired biomimetrically by the structure of wood and wood composites.

The influence of matrix modification on fracture The fracture behavior of composite rubber particle-toughened polymethylmethacrylate has been investigated over a wide range of test speeds, encompassing impact conditions. When the entanglement density of the matrix was increased and its glass transition temperature reduced by copolymerization, there were significant increases in the crack initiation and propagation resistance of the particle Progress in Polymer Science Vol 98, November 2019 Stimuli-chromism of photoswitches in smart polymers:Recent advances and applications as chemosensors Amin Abdollahi, Hossein Roghani-Mamaqani, Bahareh Razavi Article 101149
