The combination of ductile Bombyx Mori silk fibre with thermoplastic matrices, combined the use a woven architecture, leads to composites quasi-isotropic strength. Bending and tensile properties were determined for (0,90)s twill weave composites, different polymers as reference epoxy resin. Thermoplastic are isotropic in strength (about 135 MPa at 50% volume fraction) due high elongation failur...

We perform extensive Monte Carlo simulations of a two-dimensional bent hard-needle model in both its chiral zig-zag and its achiral bow-shape configurations and present their phase diagrams. We find evidence for a variety of stable phases: isotropic, quasi-nematic, smectic-C, anti-ferromorphic smectic-A, and modulated-nematic. This last phase consists of layers formed by supramolecular arches. ...

A quasi-linear diffusion model including both pitch angle and energy diffusion, adiabatic ompression and convective motion with the solar wind flow has been used to investigate the cometary ion pickup process along the Sun-comet line at comet Halley. The total pickup ion densities and magnetic turbulence spectrum levels observed by Giotto were used to constrain the quasi-linear model. Compariso...

The paper proposes a novel approach for the geometrical model calibration of quasi-isotropic parallel kinematic mechanisms of the Orthoglide family. It is based on the observations of the manipulator leg parallelism during motions between the specific test postures and employs a low-cost measuring system composed of standard comparator indicators attached to the universal magnetic stands. They ...
