Various peel-off experiments can be used to determine the adhesion strength of various fibres. Among them was the "T" type peel-off test, which measures the adhesions between fibres. The use of organic and inorganic fillers in flake or powder form will alter the adhesive properties of the binders as well as the adhesive strength between the fibres. In this study, the adhesion strength between three different varieties of glass fibres (C-Glass, E-Glass, and S-Glass fibres) with a PLA core has been investigated. As a binder, an epoxy resin was used, and the resin was modified with inorganic additives such as alumina, bentonite, and silicon carbide. Peel-off testing was used to examine the effect of additives on the bonding strength between a thermoplastic core and a synthetic fibre. The addition of inorganic compounds was found to reduce the adhesion strength between the fibres and the core. In order to evaluate the initial adhesion between the filaments and the core, nine specimens were fabricated without the addition of any additives and their strengths were determined. Maximum adhesion strength of 71.8 MPa was recorded for the neat resin. The adhesive strength after inclusion of additives was observed to decrease by 18.14%, and recorded maximum peel-off strength of 58.2 MPa. Also, the inclusion percentages of the additives were found to be the most influential factor in determining the composites' adhesive properties. Validation tests were also conducted with the optimized results which demonstrated that the predicted and experimental results were in excellent agreement. Macro and micro approaches were employed to analyze the deformation mechanisms in order to gain a comprehensive understanding of how the additives affected the adhesion strength.

Flexible nozzle extension technology has been extensively researched throughout the world, but traditional materials cannot meet the growing demands in harsh environments. Short‐cut carbon fiber‐reinforced nitrile rubber (CF/NBR) composites, which are similar to the phenolic impregnated carbon ablator, are currently a hot research topic in this field. The mechanical properties of CF/NBR composites were experimentally tested to study the change in the mechanical behavior of a rocket engine's flexible nozzle extension section under thermal coupling. As indicated by the results, existing models cannot accurately predict changes in materials' mechanical behavior. The theoretical foundation of the nonlinear viscoelastic intrinsic model of rubber is utilized. The uniaxial tensile intrinsic model of CF/NBR composites has been improved by introducing physical parameters, such as fiber reinforcement, strain rate‐dependent correction and temperature‐dependent correction coefficients, and fiber volume fraction. Results show that the intrinsic model developed in this article provides a guide to the uniaxial tensile mechanical behavior of randomly distributed short‐cut CF/NBR composites with known mass‐part formulations and fiber volume fractions at room temperature and under different pyrolysis conditions.

Ethylene Vinyl Alcohol (EVOH) exhibits superior barrier properties to carbon dioxide and methane with intrinsic brittleness, while Polyethylene (PE) possesses a remarkable moisture barrier with high ductility. It is hypothesized that multilayer composites of PE and EVOH could offer both exceptional barriers to all greenhouse gases as well as high toughness. In the present study, hybrid multilayers composed of Polyethylene of Raised Temperature (PE-RT), Polyethylene grafted Maleic Anhydride (PE-g-MA), and EVOH were fabricated in different configurations of two to five layers. The static flexural modulus of the 5-Layer (5L) film was measured to be 80% of the single-layer EVOH and 16.8% higher than the single-layer PE-RT. The loss factor of the 5L was obtained nearly equal or slightly higher than PE-RT over the measured temperature range of 30 to 90 °C, suggesting improved damping. The formation of hydrogen bonds at the interface of EVOH and PE-g-MA significantly limited the diffusion of water vapor molecules, resulting in the water vapor barrier performance of 5L film at 82 °C outperforming the predicted value using inverse additivity rule by 45.8%. Formation of hydrogen bonding at the interface of EVOH and PE-g-MA significantly limited the diffusion of water vapor molecules. A full microscopic and chemical composition analysis of interlayers was performed to reveal the underlying connection between the structure, property, and morphology. The classical lamination theory was successfully applied and validated for predicting the dynamic properties, which could be further used for design optimization of such multilayers. The performance of the proposed 5-layer symmetric structure confirms its potential for high-temperature–high-pressure applications.
