“…At this point, the storage modulus drops dramatically, as seen in Figure 8. Attahu et al's [15] study observed a similar storage modulus pattern. Per the pattern, the valuable storage modulus range for the optimal configuration (Laminate B) (see Table 2 and Figure 8) is around 111.5 C.…”

“…Attahu et al [15] sought to incorporate recycled carbon and virgin aramid fibers (vAFs) into conventional unidirectional (UD) prepreg for possible light-weight structural applications, emphasizing a compromise between mechanical damping and stiffness performances (a measure of laminates' suitability for structural applications). The compromise was expressed in terms of the merit figure.…”

The Ashby limit for mechanical damping and stiffness trade-off must be escaped to quantify composites for structural applications. To make the composites, all the participating fibers were converted into 60 g/m 2 non-woven mats, which were then sized with 1.5 wt. percent titanate coupling, TCA-L12, before being sandwiched between two layers of 125 g/m 2 resin films and used to interleave 12 unidirectional carbon fiber reinforced polymer prepreg tapes. Using the vacuum-assisted compression molding method, the assemblage was subsequently turned into composites. The impact of micro-hybridizing recycled carbon fibers with short virgin aramid fibers on mechanical damping and stiffness trade-offs was examined. The Ashby limit was exceeded by 1600%, and compared to the control sample, the best laminate had a figure of merit that was 15.3% higher.

“…Attahu et al combined carbon fibers and aramid fibers to form composite nonwoven fabrics, and then the composites and epoxy resin were laminated with a titanate coupling agent as the intralayer adhesive. They reported that the amount of the adhesive had a negative influence on the bending performance of the resulting laminated composites [ 6 ]. Sitohang et al proposed thermoplastic laminated composites that exhibited a shear force in sporadic areas because of the misaligned or twisted intralayer fibers, which eventually caused the failure of composites [ 7 , 8 ].…”

Laminated composites have been commonly applied to all fields. When made into laminated composites, Kevlar woven fabrics are able to provide the required functions. In this study, two types of TPU are incorporated to improve the intralayer features of Kevlar/TPU laminated composites. Hence, the Kevlar/TPU laminated composites consist of firmly bonded laminates while retaining flexibility of the fabrics. Being the interlayer of the laminated composites, the TPU layer provides adhesion while strengthening the tensile property, dynamic puncture resistance, and buffer strength of Kevlar/TPU laminated composites. The test results indicate that with a blending ratio of two types of TRU being 85/15 wt%, the Kevlar/TPU laminated composites exhibit a tensile strength of 18.08 MPa. When the stacking thickness is 1 mm, the tensile strength is improved to 357.73 N with the buffering strength reaching 4224.40 N. Notably, with a thickness being 1.2 mm, the laminated composites demonstrate a dynamic resistance being 672.15 N. In the meanwhile, functional Kevlar fabrics are allowed to keep the fiber morphology owing to the protection of TPU composite films. Considering the composition of protective gear, Kevlar/TPU laminated composites possess a powerful potential and are worthwhile exploring.
