“…This can be caused by the reduced fiber reinforcement in the composite beam in the longitudinal direction so that there will be a reduction in the length of the individual fibers in the longitudinal direction of the beam so that the ACL fiber reinforcement decreases significantly. This also impacts reduce the stiffness of the composite, so it has implications for a decrease in natural frequency [49]. As reported in previous findings, the value of the natural frequency of a composite beam is always directly proportional to its stiffness value [44], [50], [51] The results on the graph also show a trend of increasing natural frequency values at the position of the exciter motor at 40 cm.…”

Technological evolution and environmental awareness have driven the improvement of quality and renewable products, especially in natural fiber-reinforced composites. This study aims to analyze the stiffness and personal frequency of ACL fiber-reinforced composite beams due to the influence of the fiber direction. Next, compare experimental values with numerical. Composite beams are produced by varying the direction of the fibers 0°/0°/0°, -45°/0°/45° and -90°/0°/90° then supported by a simple support (clamp-roll). The exciter position is placed at 0-50 cm along the composite beam, then determine the value of stiffness and vibration behavior experimentally and numerically. This research indicates an increase in the stiffness and personal frequency of composite beams in the fiber direction 0°/0°/0°. The experimental values are also greater when compared to the values obtained numerically. These findings make it possible to use ACL fiber to manufacture composite beams with vibration-enabled characteristics for various applications in engineering materials subject to vibrational forces

“…And they are influenced by the sliding interface condition on the response. 40 The variation in the frequency response and the mode shape properties depends upon the fiber orientations as shown in Figure 7. Figure 7 shows that the first two natural frequencies corresponding to bending (mode À1) and side bending (mode 2) of the laminated composites were analyzed experimentally (LDV data).…”

T‐300 6K carbon fabric fiber‐reinforced epoxy laminated composites are prepared by in‐situ and hot‐compression molding technique. The main emphasis of this study is to examine the impact of the structural deformations on fiber orientations of laminated composites during vibrational damping, stiffness, and electromagnetic interference (EMI) shielding properties. The damping properties of carbon fiber laminated composites are analyzed in terms of natural frequency and logarithmic decrement. The digital image correlation technique has been used to measure the mode shape behavior of carbon fiber reinforced polymer (CFRP) composites. The dynamic behavior of the CFRP laminated composites has significant effect on the fiber orientations in terms of storage, loss modulus, and damping ratio. The value of EMI shielding of CFRP laminated composites of T‐300 6K based CFRP polymer laminated composites has slight variations in the SET and their values are 107.17 (B‐45), 106.33 (B‐30), and 110.0 dB (B‐0). The vibrational and EMI shielding properties are showing a huge potential for these kinds of CFRP laminated composites in military and aircraft applications.Highlights CFRP laminated epoxy composites were fabricated by hand layup technique. The ply orientation of CFRP composites were affected the mechanical properties. DIC was used to determine the mode shapes of laminated composites. CFRP laminated composite exhibited excellent EMI properties.
