“…In nanotechnology, wavy interfacial morphology can enhance the overall properties of composites made of thin metallic and ceramic multilayers for magnetic, optoelectronic and high-speed electronic applications [24]. Novel fuzzy fiber reinforced composites are composed of carbon fibers, wavy carbon nanotubes and epoxy matrix, with the carbon fibers radially grown on the circumferential surfaces of the carbon fibers [14,15,28].…”

In this paper we present an internal variable-based homogenization of a composite made of wavy elastic-perfectly plastic layers. In the context of a strain-driven process, the macrostress and the effective yield surface are expressed in terms of the residual stresses, which act as hardening parameters in the effective behavior of the composite. Moreover, an approximate two-steps homogenization scheme useful for composites made of matrix with wavy inclusions is proposed and a comparison with one computational and one semi-analytical homogenization method is presented.International audienceIn this paper we present an internal variable-based homogenization of a composite made of wavy elastic-perfectly plastic layers.

“…Using CF as effective fillers is restricted by their low adhesion to polymer due to the chemical inertness of CF surface. Various methods, such as thermal or chemical modification of fiber surface [8][9][10], functionalization of polymer matrix [11], plasma treatment [12][13][14], nanotubes application [15][16][17] and other [18] were applied to improve the interfacial interaction between polymers and CF. In our previous papers the effect of thermal and chemical oxidation of CF surface on the interfacial interaction between CF and ultra high molecular weight polyethylene was investigated [19,20].…”

The aim of this study is to create composites based on the high-temperature polymer reinforced with the carbon fibers and to study interfacial interaction between carbon fibers and polymer matrix. We propose a new method to obtain polysulfone based composite materials reinforced with high-modulus carbon fibers. The influences of thermal oxidation of carbon fibers on mechanical and thermal properties of the composites were studied. It was found that the obtained composite materials have sufficiently high mechanical properties, tensile strength up to 1047 MPa and Young’s modulus up to 70.9 GPa were found. Considerable interest to the polymer composites is associated with their high performance and good mechanical and thermal properties, which enable a broad range of aerospace, automotive and medical applications. Additionally, the manufacturing process of such composites can easily be optimized and automatized, furthermore, it is not time-consuming process in relation with thermosetting polymer based composites.

“…Yazdchi and Salehi developed an analytical model based on a new 3D representative volume element to study the effect of CNT waviness on the stress transfer CNT/polymer composites. The short fuzzy fiber‐reinforced composite containing wavy CNTs subjected to the thermomechanical loading has been investigated based on shear lag models . These works show that the CNTs waviness plays an important role in the thermomechanical behavior of CNTRC.…”

In this study, free vibration behavior of functionally graded carbon nanotube‐reinforced composite (FG‐CNTRC) cylinders subjected to uniform temperature environment or thermal gradient loading is investigated by a mesh‐free method. The nanocomposite cylinders are made of a polymer matrix and wavy single‐walled carbon nanotubes (SWCNTs). The volume fraction of carbon nanotubes (CNTs) are assumed variable along the radial direction of the axisymmetric cylinder. Also, material properties of the polymer and CNT are assumed temperature‐dependent and mechanical properties of the nanocomposite are estimated by a micromechanical model in volume fraction form. In the mesh‐free analysis, moving least squares shape functions are used to approximate displacement field in the weak form of motion equation and the transformation method is used to impose essential boundary conditions. The material properties and natural frequency of the nanocomposite cylinders are derived after the derivation of cylinder temperature and by considering of the temperature and location. Effects of CNT distribution pattern and volume fraction, thermal, cylinder dimensions and CNT aspect ratio and waviness are investigated on the vibration behavior of the nanocomposite cylinders.
