Optoelectronic devices based on evaporated pentacene films Voz, C. Preliminary study of a heat storage unit using a solid-solid transition Font, J. Shore D hardness, thermal expansion, dynamic mechanical analysis (DMA), Fourier transform infrared (FTIR) spectroscopy, compression and compression set (CS) measurements are made before and after the chemical exposure. The hardness, modulus at short times, degree of relaxation and CS increases while the coefficient of thermal expansion in HNBR tends to decrease with ageing time and temperature.

Temperature is shown to impose a greater effect on the properties than ageing time in the experiment. It sharply increases in the first stage of ageing and then decreases later with further exposure which suggests that chain scission dominates in the later stages of hydrocarbon ageing.

This effect is attributed to a dramatic change in the chemical structure of aged HNBR, i. These results are also qualitatively evaluated in the context of potential sealing applications of the material. The CFRP gears were milled from a composite plate and tested in mesh with a steel drive gear under five torque loads ranging between 0. A detailed gear damage analysis is conducted by employing scanning electron microscopy and high-resolution optical microscopy. Epoxy matrix microcracking is found to be the damage mechanism that leads to the final delamination failure.

CFRP gears exhibited a significantly improved performance and a longer fatigue lifespan in comparison with the polymer and polymer composite gears. The tensile and shear behaviors of the composites in swollen state were mainly studied via molecular dynamics simulations. The simulation results showed that the introduction of CNT and GN significantly improved the mechanical properties of the swollen NBR matrix. Higher elastic modulus, tensile strength and shear modulus of the composites were obtained by the incorporation of GN as reinforcement than that of CNT.

To explore the mechanisms on the above phenomenon, the atom displacements, interaction energy between the nano-reinforcements and rubber matrices, MSD of the cyclohexane and the free volume of the polymer composites were examined and interpreted accordingly.

A bench-scale test is presented as a practicable and efficient method to assess how different fire protective systems improve the structural integrity of CFRPs during fire.

The direct flame of a fully developed fire was applied to one side of the CFRP specimen, which was simultaneously loaded with compressive force. The uncoated specimen failed after just 17 s. Protection by these systems provides fire stability, as they multiply the time to failure by as much as up to 43 times.

Bench-scale fire stability testing is shown to be suitable tool to identify, compare and assess different approaches to fire protection. Herein, a hydrophobic thermoplastic lignin with favorable film formation properties was synthesized through simple crosslinking followed by esterification reactions. The chemical structure, glass transition temperature, and hydrophobicity were determined using Fourier transform infrared spectroscopy, 1H nuclear magnetic resonance spectroscopy, differential scanning calorimetry, and contact angle studies.
