“…Among them, thermoplastic composites are gaining more and more interests by their plentiful advantages. [1][2][3][4][5] For instance, unlike thermosetting resins which form rigid three-dimensionally (3 D) cross-linked chemical structures after processing, thermoplastics are high molecular weight polymers that can be readily re-melted and re-formed. Furthermore, thermoplastic composites are usually tougher and less brittle, and show good impact resistance and damage tolerance as well.…”

High-temperature engineering thermoplastics are gaining growing interests as they not only provide a lightweight solution but also affect the manufacturing processes and efficiencies. Polyetheretherketone (PEEK) is a semi-crystalline one to meet such requirement, and has been widely used as the matrix for fiber-reinforced plastics and nanocomposites. Owing to their superior physical properties, carbon nanotubes (CNTs) can be introduced into PEEK matrix in order to further improve the performances. This article reviews the state of the art of CNT/PEEK nanocomposites, by focussing on the preparation method and their mechanical, thermal, and electrical properties. The enhanced stiffness, thermal stability, and conductive properties provide PEEK and its family members richer opportunities toward high-performance applications.

“…Discontinuous fiber-reinforced polymers play a significant role in industrial applications due to their lightweight performance and lower manufacturing costs [1][2][3]. Currently in the industry, injection molding and compression molding of long fiber-reinforced thermoplastics are widely used to produce parts with outstanding mechanical properties [4]. For example, during injection molding, fiber breakage already starts in the plasticizing section of the machine and continues as the material is forced through the gate and mold filling.…”

Validation of Fiber Breakage in Simple Shear Flow with Direct Fiber Simulation

et al. 2020

This study aims to use particle level simulation to simulate the breakage behavior of glass fibers subjected to simple shear flow. Each fiber is represented as a chain of rods that experience hydrodynamic, interaction, and elastic effects. In order to validate the approach of the model, the simulation results were compared to simple shear flow experiments conducted in a Couette Rheometer. The excluded volume force constants and critical fiber breakage curvature were tuned in the simulation to gain a better understanding of the system. Relaxation of the fiber clusters and a failure probability theory were introduced into the model to solve the fiber entanglement and thus, better fit the experimental behavior. The model showed agreement with the prediction on fiber length reduction in both number average length and weight average length. In addition, the simulation had a similar trend of breakage distribution compared to a loop test using glass fibers.

“…Long fiber-reinforced thermoplastics (LFTs) are increasingly being used in a number of industries and applications, mainly in the transportation industry, but also in electronics, durable consumer appliances, sporting goods, and even health care [1]. LFTs have become an attractive design option due to their improved mechanical properties over short fiber-reinforced thermoplastics (SFTs) while still being suitable for injection molding (IM) [2].…”

Long fiber-reinforced thermoplastics are an attractive design option for many industries due to their excellent mechanical properties and processability. Processing of these materials has a significant influence on their microstructure, which controls the properties of the final part. The microstructure is characterized by the fibers’ orientation, length, and concentration. Many characterization methods can capture the fiber orientation and concentration changes through the thickness in injection molded parts, but not the changes in fiber length. In this study, a technique for measuring fiber length in the core and shell regions of molded parts was proposed, experimentally verified, and used on injection molded 20 wt.% glass fiber-reinforced polypropylene plaques. The measured fiber length in the core was 50% higher than in the shell region. Comparison with simulation results shows disagreement in the shape of the through-thickness fiber length profile. Stiffness predictions show that the through-thickness changes in fiber length have little impact on the longitudinal and transverse Young’s modulus.
