“…Composite materials usually exhibit higher mechanical and thermal properties when compared with the conventional materials such as metals, polymers, etc. (Potluri and Koteswara, 2017; Potluri, James Paul, Abdul Kalam and Prasanthi, 2017; Potluri, Kumar, Naga Raju and Ravi Prakash Babu, 2017; Potluri and Ketha, 2015; Potluri, 2015; Daniel and Ishai, 2006; Kaw, 2006; Jones, 1999; Barbero, 2014). The composite materials are mainly made up of two important phases known as the reinforcement and the matrix phase.…”

“…Singh and Samanta (2015) reviewed the characterization of the kevlar fiber-based FRP composites. General literature about the composites and the analytical methods for the properties and their finite element method (FEM) analysis was also studied (Lee and Pyo, 2008; Lloyd, 1994; Potluri and Koteswara, 2017; Potluri, James Paul, Abdul Kalam and Prasanthi, 2017; Potluri, Kumar, Naga Raju and Ravi Prakash Babu, 2017; Potluri and Ketha, 2015; Potluri, 2015; Daniel and Ishai, 2006; Kaw, 2006; Jones, 1999; Barbero, 2014; Autodesk, 2015; ANSYS®, 2015; The MathWorks Inc., 2012; available at: www.toraycma.com/page.php?id=661 – information about carbon fiber; available at: www.matweb.com/ – information about carbon fiber).…”

Purpose The purpose of this paper is to study the effect of the addition of silicon carbide (SiC) microparticles and their contributions regarding the tensile and shear properties of the T800 fiber reinforced polymer composite at various fiber volume fractions. The tensile and shear properties of the hybrid composites where continuous T800 fibers are used as reinforcements in an epoxy matrix embedded with SiC microparticles have been studied. Design/methodology/approach The results were obtained by implementing a micromechanics approach assuming a uniform distribution of reinforcements and considering one unit cell from the whole array. Using the two-step homogenization process, the properties of the materials were determined by using the finite element analysis (FEA). The predicted elastic properties from FEA were compared with the analytical results. The analytical models were implemented in the MATLAB Software. The FEA was performed in ANSYS APDL. Findings The mechanical properties of the hybrid composite had increased when compared with the properties of the conventional FRP. The results suggest that SiC particles are a good reinforcement for enhancing the transverse and shear properties of the considered fiber reinforced epoxy composite. The microparticle embedment has significant effect on the transverse tensile properties as well as in-plane and out-of-plane shear properties. Research limitations/implications This is significant because improving the properties of the composite materials using different methods is of high interest in the materials community. Using this study people can work on the process of including different type of microparticles in to their composite designs and improve their performance characteristics. The major influence of the particles can be seen only at lower volume fractions of the fiber in the composite. Only FEA and analytical methods were used for the study. Practical implications Material property improvements lead to more advanced designs for aerospace and defense structures, which allow for high performance under unpredictable conditions. Originality/value This type of study proves that the embedment of different microparticles is a method that can be used for improving the properties of the composite materials. The improvement of the transverse and shear properties will be useful especially in the design of shell structures in the different engineering applications.

“…The research of rotating vibration cutting of honey comb core components with disc-cutter is only focusing on the test verification; mechanism study must be carried out to reveal the influence of the cutting parameters on machining quality. Potlkuri measured the elastic properties of the hexagonal honeycomb-core material through experiments [14]. Based on brittle fracture mechanics, Hu studied the cutting mechanism of the ultrasonic cutting of the honeycomb core with a sharp knife and derived a theoretical model of cutting force [15].…”

The disc-cutter is a finishing tool for the ultrasonic-cutting of paper honeycomb-core material. The cutting state directly affects the machining accuracy and surface quality of the workpiece. The cutting force is an important physical quantity and the cause of ultrasonic cutting defects of the honeycomb-core material. Due to differences in the mechanical properties and cutting performance of honeycomb-core materials and commonly used metal materials, existing metal-cutting-force models cannot be applied to the calculation of ultrasonic cutting forces in the processing of honeycomb-core materials. In response to this problem—combined with actual working conditions using the ABAQUS finite element analysis software—a finite element simulation model of the ultrasonic vibration-assisted cutting force of the disc-cutter on the honeycomb-core material was established, and the cutting curves and values were obtained. The experiment of ultrasonic vibration cutting of the disc-cutter proves that from the surface morphology of the honeycomb core, the milling-width has the greatest influence on the cutting force, and the cutting-depth has the smallest influence on the cutting force. The maximum error between the cutting force experimental results and the finite element simulation results under the same cutting conditions was 13.2%, which means that the established cutting-force finite element model is more accurate and can be used to predict the cutting in honeycomb ultrasonic vibration-assisted cutting-force value. Finally, based on the response surface method, a three-dimensional cutting force prediction model of the ultrasonic cutting honeycomb core of the disc-cutter was established by using the simulation model data. The results of this study can provide a useful basis for the improvement of cutting performance and processing efficiency in the processing of paper honeycomb-core materials.
