Using a Sliding Plate Rheometer to Obtain Material Parameters for Simulating Long Fiber Orientation in Injection Molded Composites
… determining empirical parameters in stress and fiber orientation models required to accurately simulate the fiber orientation in injection molded composites. An independent approach aims to obtain the material parameters using a sliding plate rheometer to measure the rheology of fiber …

Processing and properties of composites based on high density polyethylene and thermotropic liquid crystalline polymers
… injection molding. It was observed that when the fiber aspect ratio dropped, the composite mechanical properties decreased. When pregenerated fibrils were maintained during injection molding at temperatures above the matrix melting point, but below the TLCP melting point, microcomposites were …

Finite Element Analysis of Thermal-Mechanical Instabilities in Nonmetallic Friction Composite Material
… instability.</p> <p>Coupling analysis such as vibration coupled with thermal buckling and thermal buckling coupled with thermoelastic instability was performed. The idea behind the coupling studies was to find out if the temperature gradient alone can induce instability in brakes or clutches, or …

Modeling Fiber Orientation using Empirical Parameters Obtained from Non-Lubricated Squeeze Flow for Injection Molded Long Carbon Fiber Reinforced Nylon 6,6
Long fiber reinforced thermoplastic composites are used for creating lightweight, but mechanically sound, automotive components. Injection molding is a manufacturing technique commonly used for traditional thermoplastics due to its efficiency and ability to create complex geometries. Injection …

Design, Processing, and Characterization of Nanocomposites
… at an industrial scale. The successful incorporation of cellulose nanocrystals (CNCs) in polyamides, specifically polyamide 11 (PA 11) and polyamide 6 (PA 6), can result in a more sustainable material. However, unless polyamide nanocellulose composites can be produced at an industry scale, the …
