As contemporary emerging materials, fiber-reinforced plastics/polymers (FRP) are widely used in aerospace automotive industries and in other fields due to their high strength-to-weight ratio, high stiffness-to-weight ratio, high corrosion resistance, low thermal expansion and other properties. Drilling is the most frequently used process in industrial operation for polymer composite laminates, owing to the need for joining structures. However, it is a great challenge for operators to drill holes in FRP materials, due to the non-homogenous and anisotropic properties of fibers. Various damages, such as delamination, hole shrinkage, and burr and tool wear, occur due to the heterogeneous and anisotropic nature of composite laminates. Therefore, in this study, carbon fiber reinforced polymer (CFRP)/aramid fiber reinforced polymer (AFRP) hybrid composites (C-AFRP) were successfully synthesized, and their drilling characteristics, including burr generation and tool wear, were also mainly investigated. The drilling characteristics of CFRP and C-AFRP were compared and analyzed for the first time under the same operating conditions (cutting tool, spindle speed, feed rate). The experimental results demonstrated that C-AFRP had higher tensile strength and good drilling characteristics (low thrust and less tool wear) compared with CFRP. As a lightweight and high-strength structural material, C-AFRP hybrid composites have great potential applications in the automobile and aerospace industries after the slight processing of burrs generated during drilling.

“…4 Hybrid composites are manufactured using two or more fiber types embedded in a single matrix, which results in a new material with properties different from that of each fiber type and the matrix. [5][6][7] Hybrid composites have been used in many structural applications, including aeronautical and automotive applications, due to their improved mechanical and physical properties compared to conventional polymeric composites. 8,9 These composites can be adjusted to meet different design requirements with respect to weight, strength, impact resistance, and tolerance and cost.…”

Hybrid composite laminates are currently receiving researchers’ attention due to their specific advantages in designing laminates with improved specific strength and stiffness. One of the main disadvantages of polymeric laminated composites is their high sensitivity to notches, which cannot be avoided in design. This paper presents a comparison between two common hybridization techniques, namely sandwich and intra-ply hybridization. The study adopts experimental observations to investigate the influence of hybridization method on the flexural properties of notched carbon–aramid hybrid laminates. After four-point bending tests, the results show that the damage nature in both laminates is different. A catastrophic damage is observed for intra-ply hybrid laminates, while sandwich laminates show progressive damage. In terms of the strength, sandwich specimens show 1.3 times higher specific strength, compared to intra-ply specimens. Moreover, the bottom layers of the laminate manufactured in the sandwich fashion show minimal damage due to the high capability of the aramid/epoxy core to absorb the energy in deformation and concentrate the damage at the top layers (the compression side).

“…Carbon fiber‐reinforced plastics (CFRPs) are widely used in aerospace, nuclear engineering, general engineering and transportation due to lightweight, high modulus, high strength, and other excellent properties . Carbon fiber and CFRP have strong axial load‐bearing ability and many works have reported failure of composites subjected to axial loading . However, in some applications, such as aircraft and automobile structures, load condition is complicated and multidirectional, so CFRP tend to fail easier due to transverse stress concentration and torsional buckling .…”

This study established a torsion testing method for carbon fiber bundle combined epoxy resin and investigated torsional properties of several kinds of carbon fiber with different epoxy matrix. Torsion strength and modulus were calculated to characterize the torsional properties. The effects of testing conditions including aspect ratio of sample, testing speed and resin content in bundle on measured torsional results were ascertained for choosing appropriate conditions. Scanning electron microscope (SEM) observation on fractured sample and single fiber pull‐out test were carried out to illustrate the relationship between torsion property and the properties of carbon fiber, matrix, and interface. The experimental results show that the proposed method can obtain torsion strength and modulus with good data reliability using optimized testing conditions. Higher elongation of carbon fiber leads to larger torsion strength. SEM shows that low‐elongation carbon fiber tends to fail easier with brittle failure mode. Torsion modulus strongly depends on modulus of resin matrix, rather than tensile modulus of carbon fiber. Moreover, better interfacial adhesion between fiber and matrix results in large torsion strength when matrix elongation is at equivalent level. POLYM.
