Influence of weaving structure and hybridization on the tensile properties of woven carbon-epoxy composites

Abstract

In this study, the mechanical properties of composite materials obtained from carbon and carbon-aramid hybrid woven fabrics produced in different constructions with the same yarn and under the same production conditions were determined, and the effects of weaving structure and hybridization on the mechanical properties were investigated. For this purpose, the geometric properties of carbon fabrics made from 12 K carbon yarn with four different weaving structures and two carbon-aramid hybrid fabrics made of 12 K carbon yarn and aramid yarn with two different structures were defined, and the mechanical properties of the composite materials were investigated under uniaxial tensile loading. The mechanical properties of the composite materials produced from the carbon and carbon-aramid hybrid fabrics were compared. The effects of weaving structure and hybridization on the mechanical properties were determined. Based on the weaving construction, Young’s modulus and the tensile strength declined approximately 34–39% and 24–27%, respectively. However, Young’s modulus was 16–63% higher than the expected value for the hybrid composites.

Low Velocity Impact Behaviour of Aramid and UHMWPE Composites

“…The shape of the pit mouth was different for changing reinforcement conditions. The mouth of the pit was square-shaped if the reinforcement was woven fabric due to stress concentration occurring at the weft and warp yarn interlacing point [27]. Because of the lack of yarn interlacing points for the UD cross-plied reinforcement, the mouth of the pit was conical-shaped.…”

Mechanical characterisation of kenaf/PALF reinforced composite-metal laminates: Effects of hybridisation and weaving architectures

“…41 The increase in the yarn density of plain woven-ply eventually increases its crimp level. 42 In addition to reducing the tensile and flexural strength of FMLs, the high level of waviness and crimp also retards the energy-absorbing capacity of the FMLs. Similar findings were found in the research study conducted by Strugala et al.…”

Comparison of the impact damage resistance of non-hybrid and intra-ply hybrid carbon/E-glass/polypropylene non-crimp thermoplastic composites

“…The highest tensile, flexural and impact strength were provided by the uni-directional satin-weave hemp/PLA since the lower void content and fiber misalignments of composite are compared with basket-weave composite structures. Karahan and Karahan 11 stated that the mechanical properties of the hybrid composite materials significantly decreased by the yarn crimps increased in the woven structures. Ghasemi Nejhad and Parvizi-Majidi 12 used PEEK and PPS film-stacked carbon woven thermoplastic composites.…”

“…Some detailed studies were performed by researchers about the mechanical and impact properties of hybrid composites. [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] Swolfs et al 8 reviewed the basic mechanisms of hybrid effects to obtain the optimal design of hybrid composites. Strait et al 9 stated that there were no effects of stacking sequence, and reinforcement form was observed in terms of energy after peak load in carbon fiber-reinforced thermoplastic toughened by the hybrid epoxy composites.…”
