Stiffness and Strength Predictions of Discontinuous Fiber Composites
… will ultimately lead to the certification of discontinuous fiber composites based on analysis and modest experimental verification. A discontinuous fiber composite (DFC) material system called HexMC is considered in this study. A stochastic (Monte Carlo-type) finite-element modeling approach …

Structure-property relationships in flow formed discontinuous fiber reinforced composites
… stiffness tensor for materials containing discontinuous curverd fibers. It is demonstrated that the definition of fiber configuration and configuration averaging allow us to obtain better match with experimental results when compared to theory relying on the assumption of straight fibers. …

Mechanical Properties of Random Discontinuous Fiber Composites Manufactured from Wetlay Process
The random discontinuous fiber composite has uniform properties in all directions. The wetlay process is an efficient method to manufacture random discontinuous thermoplastic preform sheets that can be molded into random composite plaques in the hot-press. Investigations were done on the molding …

Fiber Orientation Prediction and Strength Evaluation of Composite Spur Gears Reinforced by Discontinuous Fiber
… combination of the reinforcing phase (carbon fiber, alumina, etc.) and matrix phase (polymer, ceramic, metals, etc.). Carbon fiber reinforced composites are mostly used on intricate stress sensitive structures like wings of aero plane or gear. Amount of fiber, fiber type, and size of the fiber …

The interfacial shear stress failure of flawed fiber composites
… function which expresses the expected length of discontinuous fiber segments in a uniaxially aligned fiber reinforced composite. The strength of elemental volumes of fiber, used in this derivation are inferred from 1ength versus strength tests.on individual fibers. The fibers are assumed to have …

Modeling of Microstructures and Stiffness of Injection Molded Long Glass Fiber Reinforced Thermoplastics
… in the growth of the use of injection molded discontinuous fiber-reinforced thermoplastics. During the intensive injection molding process, severe fiber breakage arises in the plasticating stage leading to a broad fiber length distribution. Fiber orientation distribution (FOD) is another …

Transverse fracture and fiber/matrix interface characteristics of hybrid ceramic matrix composites
… properties through the use of continuous fiber reinforcement; fine, randomly dispersed discontinuous fiber (or whisker) reinforcement; and a hybrid combination of both continuous and discontinuous fibers. This dissertation addresses two important aspects of determining and improving the …

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 …

Mechanics of Hybrid Metal Matrix Composites
… is as backplate materials in layered armor. Fiber reinforced composites have been used as backplate materials due to their potential to absorb more energy than monolithic materials at similar to lower weights through microfragmentation of the fiber, matrix, and fiber-matrix interface. …
