Carbon fiber modified by attapulgite for preparing ultra‐high molecular weight polyethylene composite with enhanced thermal, mechanical, and tribological properties

The increase of mechanical interlocking of the matrix and the hybrid fillers was largely responsible for the increase of mechanical interlocking of the matrix and the hybrid fillers, which could not only prevent the load and heat applied to the matrix but also minimize friction damage during the fretting wear process.

Microscale investigation on the carbon fiber surface physical properties and interfacial behavior of carbon fiber/polypropylene composites fabricated by self‐resistance electric heating technique

Both experimental experiments and molecular dynamic simulations were used to investigate the interfacial bonding properties of carbon fiber/polypropylene composites made by self-u2010resistance electric heating methods. Experimental experiments were the first to determine the temperature distribution and changes in surface physical characteristics of CFs with SRE heating. The number of grooves on CFs' surface is positively correlated to electric current magnitude, according to the experimental results, while grooves' length is negatively correlated to electric current magnitude. When IFSS applies electrical current from 12 A to 20 A, it shows that the increase in the IFSS rises from 31. 00 to 39. 11 MPa, which is in keeping with the change in the surface area of CF. The increase of the contact area between CF atoms and PP atoms aids in interfacial adhesion, according to the authors.

Establishment of interlaminar structure and crack propagation in carbon fiber reinforced epoxy composites by interleaving CNTs/PEK‐C film

The unique combination of carbon nanotubes and thermoplastic resin has shown the highest possibility in the improvement of fracture resistance for the epoxy matrix composites using the interleaving toughening process in recent years. The interlaminar structure and the resultant crack propagation path are directly affected by the hybrid arrangement of CNTs and TP resin in interlayers. The sandwich interlayer had a stronger tening effect on mode I interlaminar fracture toughness compared to the PEK/CNTs uniformly hybrid interlayer, according to the findings.

Improving the through‐thickness electrical conductivity of carbon fiber reinforced polymer composites using interleaving conducting veils

Thin carbon fiber reinforced composite composites were used as interleaving materials in this study to increase the throughu2010thickness electrical conductivity of carbon fiber reinforced composites. Interlayers between standard carbon fiber reinforcement fabrics were used as interlayers between carbon fiber reinforcement fabrics using Carbon fiber or nickel-u2010coated carbon fiber veils. The interleaved composites with CF or NiCF veils increased by over 50 fold, from 0. 18 to 9. 47 and 9. 16 S/cm, respectively, to control specimens. In the interlaminar zone, conducting veils enabled establishing an electrical pathway between the carbon fabric plies by lowering the non-u2010conducting resin rich zone.

Electrical Investigation by Tunneling Atomic Force Microscopy of Carbon Fiber‐Reinforced Panels Manufactured by Modified Resin Film Infusion

The aim of this research is to determine the electrical current map by tunneling atomic force microscopy of carbon fiber—u2010reinforced panels. The effects of the different ply numbers on the TUNA's electrical results are investigated. The CNTs were strongly tied to the fabric layers' carbon fibers. TUNA's most recent images show the presence of three-dimensional networks of CNTs in the interlayer space of carbon fibers.

Research of Continuous Carbon Fiber Content in Porous Composite Structures Produced by Using Additive Manufacturing Technology

Additive manufacturing is a process of producing 3D parts layer after layer until the final product is finished. Reinforce content plays a vital role in determining the strength, stiffness, and other characteristics of the composite structure during manufacturing. Porous continuous carbon fiber reinforced polymer composite structures are produced using fused deposition modeling extrusion based technology in this research. The porous CCFRPC structures are additively produced from two styles of infill patterns printed at three different infill densities levels. The amount of continuous carbon fiber in the composite is determined and estimated after the fabrication process, according to the dissolution method. The dissolution ASTM D 3171 standard procedure is employed to specify carbon fiber content in porous structures. The results reveal that triangular infill patterns have more reinforcement content than the grid infill pattern.
