Injection Molding of Pregenerated Microcomposites
… concerned with injection molding pregenerated microcomposites composed primarily of poly(ethylene terephthalate) (PET) as the matrix and HX1000 as the thermotropic liquid crystalline polymer (TLCP). Several factors were examined to maximize the mechanical properties of these composites, …

Synthesis of Functionalized Polysiloxanes and Investigation of Highly Filled Thermally Conductive Microcomposites
… were dispersed throughout the resins and the microcomposites were investigated as thermally conductive adhesives. Random polysiloxane copolymers containing controlled number average molecular weights (Mns) and compositions with systematically varied concentrations of hydridomethylsiloxy- or …

The processing of microcomposites based on polypropylene and two thermotropic liquid crystalline polymers in injection molding, sheet extrusion, and extrusion blow molding
… liquid crystal polymers (TLCPs), referred to as microcomposites. The processing methods used are injection molding, sheet extrusion, and extrusion blow molding. The TLCPs used are HX6000 and Vectra A950. The microcomposites are produced by drawing strands of PP and TLCPs generated by means of a …

Processing and properties of composites based on high density polyethylene and thermotropic liquid crystalline polymers
… melting point, but below the TLCP melting point, microcomposites were obtained. Microcomposites generated at the lowest temperatures had higher tensile properties than found for in situ composites and similar to glass reinforced HDPE. At 170°C the pregenerated fibers were no longer deformed during …

Micro and nano composites composed of a polymer matrix and a metal disperse phase.
… to form agglomerates. Generally the presence of microcomposites affects negatively the mechanical properties. For the nanoparticles, composites with a higher elastic modulus than that of the neat materials are achievable. For both micro- and nanocomposites it is feasible to lower the friction …

Characteristics and modeling of the fracture properties of polymer-silica microparticulate composites via macroscopic scratch tests
… on the material properties of polymer-silica microcomposites, both experimentally and theoretically. A wax mixture with spherical glass bead inclusions is developed as a model material. The hardness and fracture toughness of composites containing 0%, 5%, 10%, and 20% spherical glass bead …

Micro- and Nanostructured Polymeric Materials for art protection and Restoration
… melt-compounded Paraloid and Aquazol based microcomposites with various amounts (5÷30 wt%) of CMC and thin films of Aquazol 500 micro- and nanocomposites produced by the solution mixing method with a CMC and CNC content of 5-10-30 wt% were investigated. Several characterization techniques …

Understanding the effect of nanofillers on the properties of polypropylene and glass fiber/polypropylene multiscale composites
… have also been used for the preparation of microcomposites reinforced with short glass fibers (GF). Interfacial shear strength (ISS) was measured by means of the single fiber fragmentation test on various PP/GF microcomposites. Results show that the strength at the fiber/matrix interface can …

Degradation of polylactic acid in the presence of microsize and nanosize fillers
… polymers; by contrast, those of cationic microcomposites and anionic nanocomposites are lower or slightly lower than those of the unfilled polymers, possibly due to the reduction of the carboxylic group catalytic effect through neutralization with the hydrophilic alkaline filler. As a …

Viscoelastic and fracture behaviour of polyolefin based nanocomposites
… at an high filler loading, while glass filled microcomposites showed the traditional rheological behaviour of microparticles filled polymeric systems, with marginal enhancements of rheological properties. Elaboration of new rheological models allowed us to find important correlations between …
