“…Even slight perfection in the fabrication process can improve the laminate strength for a particular loading category. [ 29–32 ] Hence, the prediction accuracy of Anisomorphic CLD can vary with the fabrication technique and cannot be employed straight away for any random laminate or stacking sequence. Anisomorphic CLDs can be used after experimental cross‐verification as it saves enormous money and effort behind a reliable life envelope prediction.…”

Prediction accuracy of constant life diagrams (CLDs) for fiber-reinforced plastics varies with the stacking, tensile/compression dominated failure, input S-N curves, the complexity of the plot, and so forth. The article's authors propose a modified piecewise linear CLD and compare its prediction accuracy with traditional piecewise and 2-segment anisomorphic CLD. The constant amplitude fatigue life data for three different carbon fiber reinforced polymer composites multidirectional laminates that is (+45, À45, +45, and À45) 2S , (+45, À45, 0, and 90) 2S , and (0, 90, 0, and 90) 2S were generated at five different stress ratios (R = σ min /σ max ) that is, R = 0.1 and 0.5 (T-T), À1 and critical stress ratio (T-C), and 5 (C-C). The proposed modified Piecewise linear CLD considers the critical stress ratio (UCS/UTS) as a definite input node. The prediction accuracy of the proposed CLD and others was evaluated using additional fatigue testing at random stress ratios and stress levels. The proposed CLD showed the highest prediction accuracy compared to Piecewise or Anisomorphic CLD. The non-linear CLD plotted using single S-N curve data may save time and effort but achieving absolute accuracy will ultimately depend on the stacking sequence.

“…The total shielding effectiveness is calculated using Equation (4). Figures 5 and 6 depict the SE of the carbon fiber/epoxy composite sample (S0) in X-band (8)(9)(10)(11)(12) and Ku-band (12-18 GHz) with different orientations of carbon fiber as shown in Figure 1B. It has been observed that without of zirconia nanofiller grading the shielding is increased significantly with orientation both in the X-band and Ku-band shown in Figures 5 and 6.…”

“…[6] Research on polymer-based composites has increased tremendously due to their exclusive properties such as being lightweight, flexible, resistant to corrosion, and moldability with higher surface area for reflection and multiple reflections. [7][8][9][10] The carbon fiber-reinforced composite (CFRC) effectively replaces aluminum and titanium alloys due to their superior mechanical strength. [11] Besides its mechanical properties, CFRC contributes to EMI shielding.…”

The present study is on the fabrication of epoxy nanocomposites for electromagnetic interference (EMI) shielding in the X‐band and Ku‐band frequency range. Single‐layer unidirectional carbon fiber along with nano zirconia is used to achieve the required EMI shielding and mechanical strength. The microstructural study of the fabricated samples has revealed the good lamination of carbon fiber in epoxy matrix and the uniform dispersion nanoparticles provide a reduction of wettability. Dielectric parameter studies indicate an increase in permittivity and dielectric loss with the addition of zirconia nanoparticles. The shielding effectiveness (SE) shows as high as 25 dB when the electric field is parallel with the carbon fiber orientation. The addition of zirconia nanoparticles to the carbon fiber reinforced epoxy composite have enhanced the ability of microwave absorption shielding. Mechanical properties of the epoxy carbon fiber nano zirconia composites show an improvement in storage modules, activation energy, and impact resistance. It is realized that 3 wt% zirconia added epoxy carbon fiber composite shows high shielding effectiveness with good mechanical properties.

Investigation on the enhancement of electromagnetic shielding with efficient use of short carbon fiber in MWCNT‐epoxy nanocomposites

The electromagnetic interference (EMI) shielding effectiveness of the epoxy polymer composite reinforced with carbon fiber mat (CFM), short carbon fiber (SCF), and multi‐walled carbon nanotube (MWCNT) is studied in the X‐band (8–12 GHz). Single‐layer unidirectional CFM of 30 wt% epoxy composite with 0° and 90° orientations resulted in EMI shielding of 5 dB and 29.6 dB, respectively. To avoid the influence of CFM orientation on the EMI shielding, SCF of distinct weight percentages (1 and 5 wt%) with fixed weight percentage (1 wt%) of MWCNT are reinforced into epoxy matrix. The EMI shielding provided by 2 mm thick epoxy composite reinforced with 5 wt% SCF along with 1 wt% MWCNT (CNT‐SCF5) is 35.4 dB. The microstructural study revealed uniform dispersion and better adhesion of MWCNT and SCF in the epoxy matrix. The dielectric properties of the fabricated samples indicated an increase in permittivity, electrical tanδ, and conductivity with the grading of SCF and MWCNT. The mechanical properties such as tensile strength and strain of the CNT‐SCF5 showed an increment in ultimate tensile strength and Young's modulus. The homogeneous CNT‐SCF5 epoxy composite with enhanced EMI shielding ability and mechanical properties could be utilized as an efficient EMI shielding material.
