“…It was observed that the loss factor (η) of ramie fiber-reinforced composites (RFRCs) was 0.0129 at free vibration condition, which is over 30% higher than that of jute fiber-reinforced composites (JFRCs). Vibration behavior of a multilayer composite laminate can also be controlled via hybridization through using alternative symmetrical or asymmetrical plies [44]. Figure 17 shows typical vibration responses of glass-, carbon-, glass/ramie-, and carbon/ramie-reinforced composites.…”

Plant fiber-reinforced composites have raised great attention among materials scientists and engineers during the past decade. Most of the efforts were put on the interfacial modifications to improve the mechanical properties of the composites so that they could partly replace the currently largely used glass fiber-reinforced composites. The modifications were mainly focused on the surface treatment of plant fibers so that mechanical or chemical bonding between plant fibers and polymeric matrices could be set up. However, the unique hierarchical microstructures of plant fibers make the building up of multiscale interfaces possible so that more forces or energies would be needed to fracture the plant fiber-reinforced composites. The additional hollow structures could also bring benefits for sound absorption and damping properties. Therefore, this article reviewed R&D efforts to develop structural and functional-integrated plant fiber-reinforced composites by fully taking advantage of the hierarchical microstructures of plant fibers. Firstly, the unique hierarchical structures of plant fibers were revealed and hierarchical theoretical models for mechanical properties were discussed. Then, the modification, characterization, and evaluation of plant fibers in terms of their interfacial properties with polymeric matrices, especially by nanotechnologies with the consideration of their unique hierarchical microstructures, were reviewed. Finally, the design and manufacture of quasi-structures and structural-damping components using technologies that have been fully adapted to state-of-the-art industrial processes for use in critical applications, such as aircraft interiors, rail transportation vehicles, and constructions, were also introduced.

“…However, the typical CFRP may have very poor damping property (loss tangent is 0.01) in a narrow temperature region. Various efforts have been made worldwide to improve the damping properties of CFRPs [1][2][3][4][5][6][7][8][9]. Sandwich structures have a high damping capability when viscoelastic materials are used in the core layer [10][11][12][13][14][15][16][17][18].…”

To improve vibration damping performance of Carbon Fiber Reinforced Plastics (CFRPs), a damping layer is typically sandwiched between two CFRP layers. Herein, a hybrid damping layer design is proposed, to obtain an optimum structure with high performance in both stiffness and damping. The sandwich structure is investigated for different materials of core layer, using different combinations of damping materials. A high-damping CFRP sandwich structure with a wide temperature range is proposed, which uses polyurethane and polyester in the hybrid core layer. The damping property and bending stiffness of the designed CFRP laminate is controllable by using either parallel mode or series mode with different ratios of the damping materials. The Ross-Kerwin-Ungar (RKU) equation is modified to predict the present hybrid core layer structures and reasonable results for both experimental and theoretical prediction were obtained.

In this article, a series of novel semi-interpenetrating polymer networks (s-IPNs) based on linear polyimide (PI) and crosslinked epoxy (EP) were firstly prepared aiming at controlling violent vibration and noise originating from operation of the machine. The damping, thermal, and mechanical performances of s-IPNs films were systematically investigated in terms of the structure of polyimide (the molar ratios of diamines) and the component ratios of PI/EP. The results indicate that PI/EP s-IPNs films exhibit prominent damping properties, and the effective damping temperature range can reach up to 58.8 C when molar ratio of diamines is 1:3 within PI and component ratio of PI/EP is 70:30. Meanwhile, all the PI/EP s-IPNs films show good thermal stability compared to cured EP and certain mechanical behaviors due to the formation of semi-interpenetrated structure. Meaningfully, the prepared novel PI/EP s-IPNs will be used as effective damping materials and have a potential application in damping fields.
