Static and dynamic compressive and tensile response of highly stretchable polyurea

Xin Wang et al.

Summary: This study investigates the mechanical response of highly stretchable polyurea elastomer at various strain rates through experiments, theoretical analysis, and numerical modeling. A compressible visco-hyperelastic constitutive model for the material is established based on the summation of Cauchy stress components, which shows good agreement with experimental data and better description of tensile response at high stretch rates.

Influence of Stress Level and Fibre Volume Fraction on Fatigue Performance of Glass Fibre-Reinforced Polyester Composites

Mahmoud Yousry Zaghloul et al.

Summary: Fibre-reinforced polymeric composite materials are increasingly being used in the repair and replacement of metallic materials due to their high stiffness. This study investigates the effects of fibre volume fraction and stress level on the fatigue performance of glass fibre-reinforced polyester (GFRP) composites, and validates prediction models for fatigue life.

Effects of Fiber Volume Fraction and Length on the Mechanical Properties of Milled Glass Fiber/Polyurea Composites

Jing Qiao et al.

Summary: Polyurea composites reinforced with milled glass fiber were studied to investigate the effects of fiber volume fraction and length on the morphological and mechanical properties. SEM and FTIR analysis revealed a uniform distribution and improved interfacial bonding of the composites with longer fiber. The addition of milled glass fiber led to more phase mixing and decreased hydrogen bonding in the polyurea matrix, but had a negligible effect on the H-bond strength. The compressive behavior of the composites was nonlinear and strain-rate-dependent, with higher volume fraction and longer fiber length leading to increased elastic modulus, stress, and energy absorption capability. The storage and loss moduli of the composites also increased with fiber volume fraction and length. The study highlights the improvement in stiffness and energy dissipative capability of polyurea composites with the addition of milled glass fiber.

Free volume based nonlinear viscoelastic model for polyurea over a wide range of strain rates and temperatures

Chencheng Gong et al.

Summary: This paper develops a nonlinear viscoelastic constitutive model for polyurea, considering its complex nonlinear stress-strain response. The model takes into account nonlinear viscoelasticity, entropic and energetic elasticity, as well as the interaction of chain segments, stretch of molecular chains, and covalent bonds from the perspective of molecular structure.

Evaluation of effectiveness of polymer coatings in reducing blast-induced deformation of steel plates

Damith Mohotti et al.

Summary: The study investigated the impact of Polyurea coating on the blast-induced response in steel plates, finding that back face coating reduces residual deformation and eliminates melting of the Polyurea layer, while front-face coating can be used to provide additional standoff distance.
