“…From the results it can be seen that the values for both fiber types were similar. The values for both were also notably higher than what have been reported elsewhere [ 22 , 31 ] with untreated CF and PA6. This is significant, as it indicates that an excellent level of interfacial adhesion was achieved with the rCF s in the thermoplastic matrix.…”

Currently, the vast majority of composite waste is either landfilled or incinerated, causing a massive burden on the environment and resulting in the loss of potentially valuable raw material. Here, conventional pyrolysis and reactive pyrolysis were used to reclaim carbon fibers from aeronautical scrap material, and to evaluate the feasibility of using reclaimed carbon fibers in structural components for the automotive sector. The need for fiber sizing was investigated as well as the behavior of the fiber material in macroscopic impact testing. The fibers were characterized with the single fiber tensile test, scanning electron microscopy, and the microbond test. Critical fiber length was estimated in both polypropylene and polyamide matrices. Tensile strength of the fiber material was better preserved with the reactive pyrolysis compared to the conventional pyrolysis, but in both cases the interfacial shear strength was retained or even improved. The impact testing revealed that the components made of these fibers fulfilled all required deformation limits set for the components with virgin fibers. These results indicate that recycled carbon fibers can be a viable option even in structural components, resulting in lower production costs and greener composites.

“…The apparent ILSS of the composite is usually used to characterize adhesion quality between the fiber and matrix [39,51,56]. Likewise, a transverse fiber bundle test technique has been proposed to assess the fiber/matrix interfacial adhesion without making composite materials [48,82].…”

“…This indicates that the manufacturing process impacts the final properties of the prepared composites. Li et al [82] stated some details about interfacial parameters between such materials, which may be useful for further simulation studies for optimizing all related parameters that affect mechanical properties such as CF length, loading and processing conditions, annealing temperature, and cooling rate. They used a transverse fiber bundle test which was proposed to assess the fiber/matrix interfacial adhesion without manufacturing composite materials.…”

Carbon fiber-reinforced polymers are considered a promising composite for many industrial applications including in the automation, renewable energy, and aerospace industries. They exhibit exceptional properties such as a high strength-to-weight ratio and high wear resistance and stiffness, which give them an advantage over other conventional materials such as metals. Various polymers can be used as matrices such as thermosetting, thermoplastic, and elastomers polymers. This comprehensive review focuses on carbon fiber-reinforced thermoplastic polymers due to the advantages of thermoplastic compared to thermosetting and elastomer polymers. These advantages include recyclability, ease of processability, flexibility, and shorter production time. The related properties such as strength, modulus, thermal conductivity, and stability, as well as electrical conductivity, are discussed in depth. Additionally, the modification techniques of the surface of carbon fiber, including the chemical and physical methods, are thoroughly explored. Overall, this review represents and summarizes the future prospective and research developments carried out on carbon fiber-reinforced thermoplastic polymers.

“…PA's impact strength must be increased before it can be utilized in some engineering or packaging applications. Reinforcing PA using glass fiber [6][7][8][9] and other polymers such as elastomers [1,10] and thermoplastics has been attempted to enhance its impact strength. As a reactive compatibilizer, styrene-ethylenebutadiene-styrene (SEBS) rubber [11][12][13][14][15] has been utilized in PA6 blends.…”

In this study, the mechanical performances of neat Polyamide 6 (PA6) polymer, 20wt.% glass fiber reinforced PA6, and 8% SEBS elastomer with 20% glass fiber reinforced PA6 composite were investigated. Composite materials were first produced in the form of granules by using a twinscrew extruder. Later, mechanical test samples were molded, in accordance with the American Society of Testing Materials (ASTM) standards, using an injection molding technique. Mechanical parameters such as tensile strength, tensile modulus, elongation at break, impact strength, flexural strength, and flexural modulus were determined by tensile, impact, and bending tests. With the addition of 20wt.% glass fiber reinforcement to the PA6 polymer matrix, properties such as tensile strength, tensile modulus, flexural strength, and flexural modulus increased, while properties such as elongation at break and impact strength decreased. For the 20% glass fiber reinforced PA6 composite with 8% SEBS rubber additive, while the impact strength increased by 177%, other mechanical values decreased. The fractured surface microstructure images of the samples obtained from the tensile tests were examined using a scanning electron microscope.
