Structural components used in civil engineering applications are often subjected to compressive loads. Unlike the tensile strength of fiber-reinforced polymer (FRP) materials, their compressive strength is resin-dominated, exhibiting lower values and more ...
Diffusion of CO2 in polylactide was modelled by assuming the diffusion coefficient to depend on CO2 concentration, c, according to D[c]=D[0]exp[Ac], where D[0] and A are empirical constants, with the aim of optimizing impregnation of nominally amorphous an ...
Composite sandwich panels comprising fibre reinforced polymer (FRP) skins and lightweight material cores are being increasingly used in civil engineering. In several applications, such as fa ades, roof structures and bridge decks, these panels may experien ...
Fiber Reinforced Composites (FRCs), due to their intrinsic heterogeneity, are generally affected by complex multi-scale failure mechanisms leading to the formation of matrix cracks that are difficult to detect and repair. FRCs with the ability to heal and ...
Lactic acid (LA) is considered for the diversification and value addition to sugar industry in South Africa, through a bioconversion of sugarcane bagasse and leaves. A bioconversion process was modeled in Aspen Plus (R) V8.6 and its environmental impacts w ...
A synthetic strategy to polydimethylsiloxanes and polymethylsiloxanes containing thiol functions as end- or side-groups, respectively, is presented. Such polymers are important starting materials for elastomeric networks and postpolymerization modification ...
Blends of commercial epoxy monomer with a 4,4'-diaminodiphenylsulfone hardener and poly(epsilon-caprolactone) (PCL) were evaluated for their potential as a self-healing matrix for fiber-reinforced composites, based on their room temperature toughness and s ...
Polymer-based composite materials are used to manufacture ultra-light panels, massively introduced in the last decades in the aeronautical industry, as a potential solution to reduce the energy consumption and combustion emissions. Safety being the main co ...
Structures made of FRP composites have been shown to provide efficient and economical applications in bridges and piers. They are being increasingly used due to their several advantages when compared to traditional materials, namely, the lightness, strengt ...
Field observations indicate that during the 2010 Deepwater Horizon accident, approximately one quarter of the released petroleum mass became entrapped below the sea surface, but the sequestration mechanisms remain unexplained. A multiphase buoyant plume mo ...
