“…e addition of micro fillers has enhanced greatly the physical and mechanical properties of composites. Compressive strength is a critical material attribute that can usually only be evaluated by experimentation [9]; compressive strengths of unidirectional fiberreinforced composites may be predicted. Endings of stiff carbon fibres could make considerable indentations on the contact surface during compression testing using AS4/ 3501-6 carbon/epoxy off-axis specimens, preventing full shear deformation [10].…”

Using pebble and fibre in an epoxy matrix, the mechanical, dynamic, and thermal characteristics of a composite were examined. Tensile, flexural, impact, and interlaminar shear strengths are experimentally determined. In this study, we compare the mechanical performance of carbon fibre composites composed entirely of conventional epoxy (NE). The results of a comparative investigation using 15 and 20% carbon fibre in an epoxy matrix are presented. Additional categories for compressive strength and damping ratio were defined based on this performance. The epoxy resin was combined with carbon fibre (15 wt% and 20 wt%) in a unidirectional arrangement and manufactured with different fillers like pebble. The goal of this research is to better understand the bonding mechanisms between damping materials and the resin matrix in order to increase interfacial bonding performance. This information is required for both selecting the appropriate material for applications and developing a composite construction using that material.

“…The rise in delamination diameter was also noticed for samples that had filler inclusions of more than 8 wt% Al 2 O 3 . Haro et al [ 55 ] reported a similar pattern of outcomes with nanoalumina inclusion. Natural fiber SGF and synthetic fiber Kevlar were utilized as reinforcements in this study, however, natural fibers such as hemp and jute were used as reinforcements in prior studies for conducting ballistic impact tests, with the energy absorption for jute and hemp fibers being found to be 30.5 J.…”

Present research work aims to know the significance of nanofiller aluminum oxide (Al 2 O 3 ) loading on viscoelastic behavior and ballistic impact behavior of Kevlar/snake grass fiber (SGF) hybrid epoxy composites. A mechanical stirring process was used to modify the epoxy matrix by adding different weights (0%, 2%, 4%, 6%, 8%, and 10%) of the nanofiller Al 2 O 3 . The manual lay-up method by subsequent hot pressing was used to create the Al 2 O 3 -added Kevlar/SGF hybrid epoxy composites. The tensile, interlaminar shear, flexural, and impact strength were tested. When compared to the control sample, the 2 wt% fillerloaded hybrid composites had higher tensile strength, flexural strength, impact strength, and interlaminar shear strength by 6.42%, 6.11%, 53.11%, and 11.08%, respectively. Furthermore, morphological analysis was performed on the mechanically tested samples to forecast the failure mechanism. The 2 wt% filler-loaded hybrid epoxy composites demonstrated effective interfacial bonding with matrix and minimal fiber pullout, according to micrograph images.The developed hybrid composites were subjected to dynamic mechanical analysis (DMA). The DMA results demonstrated that hybrid composites with 8 wt % filler had better viscoelastic behavior than the control sample. Under a ballistic impact test, the ability of the Kevlar/SGF composites with nano Al 2 O 3 inclusion to absorb energy was assessed. According to the findings, incorporating nano Al 2 O 3 into Kevlar/SGF composites strengthened their ballistic impact resistance and energy absorption. The addition of 8 wt% nanofiller resulted in high energy absorption, according to ballistic impact studies. As compared to the control sample, the composite sample with 8% filler reveals a 68.80% enhanced energy absorption. Furthermore, the composite samples with the optimal wt% Al 2 O 3 nanofiller can be used to mold impact-resistant materials for a bulletproof vest.

“…These fibres are mainly used to reinforce different composite materials, typically dedicated for parts subjected to friction because it has been proven that the addition of aramid fibres leads to an improvement in the friction coefficient [ 51 ]. Kevlar short fibres are also recommended for ballistic applications such as armour made of high-density polyethylene (HDPE) reinforced with Kevlar short fibres [ 52 ]. It was shown that the additional reinforcement of the composite materials with Kevlar short fibres based on HDPE reinforced with wood flour leads to a significant increase in impact strength [ 53 ].…”

Kevlar and carbon fibres and fabrics have won a leading place in the structure market, although such materials are not cheap, and are increasingly used for reinforcing and strengthening structural elements in the civil engineering, automotive, aerospace and military industries, due to their superior mechanical properties, especially in terms of strength. The mechanical characteristics of such composite materials must be known in order to numerically simulate the mechanical behaviour of such structures in terms of the distribution of stresses and strains. It has also become a necessity to understand the effects of reinforcement with both types of fibres (carbon fibres and Kevlar fibres) on the mechanical properties, especially on the impact properties of such composites. This review aims to expose the main advantages and disadvantages of the hybridization of carbon and Kevlar fibres. For this reason, an overview is presented concerning the main characteristics (tensile strength, flexural strength, impact strength, coefficient of thermal expansion and so on) for carbon and Kevlar fibres and also for hybrid Kevlar–carbon composite materials to aid in the design of such hybrid composite materials. Finally, some civil construction rehabilitation and consolidation applications of the composites reinforced with carbon fibre, Kevlar fibre or with hybrid Kevlar–carbon fabrics are highlighted in the last part of the paper.
