Summary: Glass fiber-reinforced phenolic resins are suitable substitutes for aluminum die-cast materials due to their ability to meet high thermomechanical and chemical demands. By increasing the length of glass fibers and developing a novel mixing element, the mechanical properties of the resins can be improved. Despite the reduction in fiber length, the mechanical characterization shows an increase in tensile strength for long fiber-reinforced materials.

Summary: Microcellular injection molding (MIM) is a flexible, efficient, and environmentally friendly foaming technology used to prepare plastic foams with complex shapes. Mold-opening microcellular injection molding (MOMIM) was used to prepare high-performance polypropylene/glass fiber (PP/GF) composite foams, which exhibit significantly improved mechanical properties compared to pure PP foams. MOMIM can enhance the flexural modulus of molded samples, and the addition of glass fiber in PP/GF composites can greatly increase tensile strength and modulus.

Summary: This study investigates the effects of injection temperature, injection pressure, and fiber content on the mechanical properties of weld lines in carbon fiber-reinforced nylon (PA-CF) composites. The results indicate that the presence of weld lines negatively affects the mechanical properties of the composites, primarily due to poor fiber orientation in the weld line regions. Additionally, increasing injection temperature and pressure can improve the mechanical properties of composites with low fiber content, but weaken those with high fiber content.

Summary: The study investigated the anisotropic mechanical behavior of hybrid injection molded short and continuous fiber-reinforced thermoplastics and used numerical simulations to predict the resulting mechanical properties. The results showed that the flow rate during injection molding had a significant effect on fiber orientation but not on fiber length, leading to improved prediction of mechanical behavior under flexural loading. Using implemented injection molding data in the numerical simulation significantly reduced the deviation between predicted and experimentally measured flexural strength.

Summary: This study evaluated the changes in mechanical and thermal properties of polyhydroxybutyrate-based composites with various additives, showing that the addition of carbon fibers and microspheres had minimal impact on thermal stability, while polyethylene glycol showed slight improvements at higher molecular weights. All composite samples exhibited a decrease in hardness and compressibility, indicating potential advancements in integrating biodegradable plastics into everyday products.

Summary: A study was conducted on the relationship between injection molding parameters and the resulting fiber length, orientation, and mechanical properties of highly reinforced long fiber thermoplastic (LFT) polypropylene (PP). It was found that the longest fibers were obtained under the conditions of lowest backpressure and highest screw speed. The importance of backpressure increased as the amount of glass fiber reinforcement increased, contrary to less reinforced thermoplastics. Injection speed did not affect fiber breakage, but had a significant impact on fiber orientation and tensile strength, especially when the average fiber length was below 1000 μm. When the average length exceeded 1000 μm, the fibers formed a mesh that thickened the core region and hindered orientation, resulting in reduced tensile strength but improved impact resistance.
