“…In order to improve the dispersibility of carbon nanofibers in the cement-based matrix, dispersant and ultrasonic treatment were firstly applied to prepare a uniformly dispersed aqueous solution of carbon nanofibers. When the ultrasonic capacity is 2800 kJ/1 and the ratio of dispersant to carbon nanofibers is 4 : 1, the best dispersion suspension can be obtained [ 7 ].…”

In order to explore the influence law and action mechanism of carbon nanofibers on the basic mechanical properties of concrete, the author proposes the mechanical properties and microscopic mechanism of carbon nanofiber-modified concrete. Concrete was prepared with different dosages of carbon nanofibers, and the compressive strength, flexural strength, and splitting strength of carbon nanofiber-modified concrete were tested, and the modification mechanism was explored. Experimental results show that an appropriate amount of carbon nanofibers can improve the mechanical properties of concrete. When the dosage is 0.3%, the mechanical properties of carbon nanofiber-modified concrete are the best, and its compressive strength, flexural strength, and split tensile strength are increased by 9.2%, 13.2%, and 17.5%, respectively, compared with plain concrete. Carbon nanofibers can form a three-dimensional network structure inside the concrete, which can improve the microscopic morphology of the concrete, enhance the toughness and integrity of the concrete, fill the pore defects inside the concrete, refine the pore size distribution, and consume part of the fracture failure energy when the concrete is damaged.

“…Therefore, in the 30PPI-C4 composite, the Orowan strengthening mechanism improves the strength of the C4 composite. 34 The maximum volume fraction of C4 composite that could be fabricated was 18%; when more than 30PPI was used, it was difficult to infiltrate the matrix. Moreover, at higher PPI, the strut thickness will reduce, which in turn will reduce the strength of C4 composite.…”

Ceramics are used in ballistic protection applications for their high hardness and compressive strength; however, they are brittle and shock-sensitive. Co-continuous ceramic composite (C4) infused with a ductile phase can compensate for the brittleness of the ceramic and increase energy absorption with a potential weight reduction in comparison with present multilayer armours. Nevertheless, the research on C4 for armour applications is in its infant stage. This article aims to investigate the energy absorption characteristics of C4 composites with ballistic grade Al5083 infiltrated into different volume fractions of SiC foam (10PPI, 20PPI and 30PPI). The infiltrated C4 samples have 13, 15 and 18 volume percent of SiC in 10PPI-C4, 20PPI-C4 and 30PPI-C4 respectively. The uniaxial compression test of C4 samples revealed that 30PPI-C4 samples have 135 times high compression strength than ceramic preforms and hardness of C4 also enhanced by 13% for 30PPI-C4 samples. The gas gun impact and Split Hopkinson Pressure Bar (SHPB) tests on the 30PPI-C4 specimens reveals that their specific energy absorption (SEA) are 78% and 30% higher than those of 10PPI-C4 and 20PPI-C4 respectively.

“…One of the most common methods to study the strengthening mechanism and theoretical prediction of SiCp/Al composites is finite element numerical simulation. The finite element method can obtain the complete stress and strain field at the meso scale to reflect the macro-response characteristics of the composites, so as to quantitatively analyze the dependence of the macro-properties of the composites on the mesostructure [5][6][7].…”

In this paper, considering the strength and geometric discrete distribution characteristics of composite reinforcement, by introducing the discrete distribution function of reinforcement, the secondary development of ABAQUS is realized by using the Python language, the parametric automatic generation method of representative volume elements of particle-reinforced composites is established, and the tensile properties of silicon carbide particle-reinforced aluminum matrix composites are analyzed. The effects of particle strength, particle volume fraction, and particle random distribution on the mechanical properties of SiCp/Al composites are studied. The results show that the random distribution of particles and the change in particle strength have no obvious influence on the stress–strain relationship before the beginning of material damage, but have a great influence on the damage stage, maximum strength, and corresponding failure strain. With the increase in particle volume fraction, the damage intensity of the model increases, and the random distribution of particles has a great influence on the model with a large particle volume fraction. The results can provide a reference for the design, preparation, and characterization of particle-reinforced metal matrix composites.
