“…The stress distribution on the CF/PEEK composites was simulated by COMSOL software (Figure 12(c),(d),(e)). 33,34 Figures (e),(d) reveal that the material could deform when a load is applied to the centre of the material. When the load is applied to the front surface of the material, the front of the material is subject to extrusion stress, whilst the back of the material bears the maximum shear and tensile stresses.…”

The interfacial interactions of carbon fiber (CF)‐reinforced polymer composites is a key factor affecting the overall performance of the material. In this work, we prepared a sulfonated poly(ether sulfone)–graphene oxide mixed sizing agent to modify the interface of CF/PEEK composites and improve the interfacial properties between the PEEK matrix and CF. Results showed that the mechanical and interfacial properties of CF/PEEK composites are improved by the sizing agent. Specifically, the flexural strength, flexural modulus and interlaminar shear strength of the materials reached 847.29 MPa, 63.77 GPa, and 73.17 MPa, respectively. Scanning electron microscopy confirmed markedly improved adhesion between the resin matrix and fibers. This work provides a simple and effective method for the preparation of high‐performance CF/PEEK composites, which can improve the performance of composites without degrading the mechanical property of pristine CF.

“…Also, a unique technique has been presented for fabricating high-performance carbon fiber/PA12/epoxy composites by laser sintering and post-infiltration [ 72 ]. Moreover, several articles reported decreased mechanical performance at high fiber loadings due to increased porosity, indicating the critical need to address this defect in order to optimize the benefits of fiber inclusion [ 135 , 136 ]. Other research indicated that the addition of continuous fiber reinforcement into the resin composition improved mechanical properties such as tensile strength [ 119 ].…”

In this research article, a mini-review study is performed on the additive manufacturing (AM) of the polymeric matrix composites (PMCs) and nanocomposites. In this regard, some methods for manufacturing and important and applied results are briefly introduced and presented. AM of polymeric matrix composites and nanocomposites has attracted great attention and is emerging as it can make extensively customized parts with appreciably modified and improved mechanical properties compared to the unreinforced polymer materials. However, some matters must be addressed containing reduced bonding of reinforcement and matrix, the slip between reinforcement and matrix, lower creep strength, void configurations, high-speed crack propagation, obstruction because of filler inclusion, enhanced curing time, simulation and modeling, and the cost of manufacturing. In this review, some selected and significant results regarding AM or three-dimensional (3D) printing of polymeric matrix composites and nanocomposites are summarized and discuss. In addition, this article discusses the difficulties in preparing composite feedstock filaments and printing issues with nanocomposites and short and continuous fiber composites. It is discussed how to print various thermoplastic composites ranging from amorphous to crystalline polymers. In addition, the analytical and numerical models used for simulating AM, including the Fused deposition modeling (FDM) printing process and estimating the mechanical properties of printed parts, are explained in detail. Particle, fiber, and nanomaterial-reinforced polymer composites are highlighted for their performance. Finally, key limitations are identified in order to stimulate further 3D printing research in the future.

“…In decades, chopped carbon fiber (CCF) [1][2][3][4][5][6][7][8] reinforced epoxy production sound lightweight, excellent mechanical properties which have enjoyed the significant applications of automotive and national defense industry. Generally, the CCF reinforced polymer structures usually suffer a load that far away from failure intensity, and one of fiber's main functions is to transfer the load from one fiber to another.…”

In this work, a dual‐scale homogenization (DSH) procedures including the representative volume element (RVE) and Unit cell (UC) with Halpin–Tsai models in the UC scale and space direction‐sensitive Hotelling expansion (SDSHE) models in RVE scale separately. These two methods are introduced and implemented to predict the response of effective elastic properties in chopped fiber reinforced epoxy matrix structures. A post‐processing scheme of subdomain in UC scale based on Gauss theorem is proposed in SDSHE method, which is used to extract the average strain and stress in UC three‐dimensional structure. In addition, the X‐ray computed tomography was used to determine the fourth order tensor orientation angle and the probability distribution information of chopped fiber length in testing samples. Homogenization properties in RVE scale, and inclusion volume fraction (VF), thickness of interface and orientation tensors are designed in UC scale and compared. The excellent correlations with experiments prove the effectiveness of the proposed models. Furthermore, the algorithm proposed in this paper realizes the homogenization of the two scales in the process of numerical analysis, and it will effectively take into account many problems that cannot be achieved by other algorithms, such as the path strain of the model, the thickness of the interface, and so on.
