Summary: The main purpose of this research is to develop a model for investigating creep phenomenon in polymeric composites reinforced with randomly oriented short fibers. The creep phenomenon is first analyzed at the micro-scale in a representative volume element of a long-fiber composite using an implicit approach. Then, a macro-scale creep analysis is performed at the laminate level. The creep behavior of randomly oriented short fiber composites is obtained by integrating laminate analogy with creep modeling technique, and the results are compared with published experimental data.

Summary: A statistical assessment of 25 constitutive models for PUEs showed that models with both the first- and the second-invariant, in logarithmic or exponential expression for strain, perform better in interpreting stress-strain curves, with an average coefficient of determination of 0.990 and a percentage of well-fitted curves of 92%.

Summary: This article proposes the use of maleic anhydride grafted polypropylene (MAPP) as the matrix resin for continuous glass fiber reinforced thermoplastic prepreg. The compression molding parameters and plying sequences are optimized. The mechanical results show that the tensile and bending strength are maintained while the modulus is significantly enhanced in the fiber-metal laminates. The findings are important for designing lightweight structural parts in automobile applications.

Summary: The study focuses on the fabrication and thermomechanical characterization of fully recycled composite materials based on HDPE reinforced with bio-natural carbonized Luffa cylindrica inclusions. The use of the twin roll mill process enabled the production of polymer composites with variable c-LC content, with morphological and thermomechanical analysis confirming the reinforcing effect of biochar inclusions on HDPE thermoplastic. This opens the way for the potential use of such fully-recycled biochar thermoplastic composite materials in structural and semi-structural applications.

Summary: Reactive blending of PC with PDMSOH improves impact strength at sub-zero temperature, with the viscosity and concentration of the siloxane impacting modification differently. By selecting a suitable viscosity of PDMSOH, it is possible to enhance low-temperature ductility without sacrificing melt flow property. Different grades of siloxane modified PC can be developed for low-temperature applications.

Summary: In this study, the interfacial compatibility between PBAT and PPC composites was improved by adding reactive compatibilizer TGIC, which enhanced the thermal stability and mechanical properties of the composites. PBAT/PPC/TGIC films prepared at 1 phr TGIC content showed higher tensile strength and elongation at break, and the water vapor transmission rate decreased by 33%.

Summary: The combination of ionizing radiation and accelerated weathering in oxo-degradable plastic bags can lead to the fragmentation of polyethylene chains, accelerating the activation of pro-oxidant additives and enhancing the degradation process. Additionally, polyethylene molecules can be degraded with ionizing radiation pre-treatment even in the absence of pro-oxidant additives.

Summary: This study investigated the influence of masterbatches with different carrier resins on the impact resistance and morphology of an ABS/SAN blend. It found that masterbatches based on PS led to immiscibility, while those based on ABS and SAN showed no significant impact. Theoretical calculations were in good accordance with experimental results, suggesting the potential for predicting suitable masterbatch carriers based on solubility calculations between blend partners.

Summary: The bearing capacity of CF/PEEK riveted joint can be enhanced by interference fit, but excessive interference fit size may cause fiber damage. The appropriate interference fit size range is 2.0% to 2.6%, which is larger than that of thermoset composites.

Summary: The sizing process is crucial for protecting carbon fiber surface and improving interfacial adhesion. In this study, polyetherimide (PEI) was chosen as the sizing agent for CF reinforced polyetheretherketone (CF/PEEK) composites, leading to enhanced mechanical properties and interfacial shear strength. The use of emulsion type sizing agent showed promising potential to replace solvent-based sizing agent in processing high temperature continuous CF reinforced thermoplastic composites.

Summary: Using ionizing radiation for sterilization of medical and health care products is a common method, but there is a lack of systematic study on the effects of different dose ranges and types of ionizing radiation on polymers. The study found that most polymers are not affected in terms of mechanical properties, but yellowing is a pronounced effect in all cases.

Summary: A series of multiblock copolymers PET-X%-E-P-E were synthesized via melt polymerization, showing good thermal stability and enhanced toughness and water absorption ability with the incorporation of E-P-E segments. The crystallization ability and mechanical properties were found to be influenced by the E-P-E content, suggesting potential applications in toughness polyester fiber production.

Summary: The study focused on the evolution of equilibrium stress in two semi-crystalline polymer materials through relaxation tests at different temperatures and stress levels. Experimental results matched with numerical results of viscoplasticity theory based on overstress, showing its aptitude for predicting anomalous relaxation behavior. The modeling capability of the Kohlrausch-Williams-Watts model was also demonstrated in predicting short-term relaxation of the materials.
