“…The metal-polymer joining techniques mainly include adhesive bonding [6], mechanical fastening [7], and hot-assisted joining or welding [8][9][10][11]. However, the potential toxicity of the adhesive or primers used during adhesive bonding mean this method is not suitable for biomedical applications.…”

In order to enhance the joint performance of Ti6Al4V titanium alloy (TC4) and ultra-high molecular weight polyethylene (UHMWPE) for biomedical applications, different structures were fabricated on TC4 surfaces via electron beam melting (EBM) method in this study. Macromorphologies and microinterfaces of TC4–UHMWPE joints produced via hot pressing technique were carefully characterized and analyzed. The effects of different surface structures on mechanical properties and fractured surfaces were investigated and compared. Strong direct bonding (1751 N) between UHMWPE and TC4 was achieved. The interfacial bonding behavior of TC4–UHMWPE joints was further discussed. This study demonstrates the importance of combining macro- and micromechanical interlocking, which is a promising strategy for improving metal–polymer joint performance. It also provides guidance for metal surface structuring from both theoretical and practical perspectives.

“…The joints showed good bearing with a ductile behavior, proving the ability of the bolted system to overcome the brittle nature of its bonded counterpart. The effects of different fastening conditions on bolted FRP-steel joints were reported throughout the last decade, highlighting the ductile behavior of the bolted system [25][26][27][28][29][30].…”

The strengthening of steel beams using hybrid fiber-reinforced polymers (HFRPs) has gained enormous attention over the last decades. Few researchers have investigated the effectiveness of the fastening techniques without a bonding agent to overcome the undesirable debonding failure of the bonded FRP–steel system. This paper reports the outcomes of experimental and numerical investigations conducted on steel beams strengthened by HFRP using steel bolts. Twenty-two steel beams were tested in four-point loading to investigate the effect of the HFRP length and the bolt arrangement on the flexural behavior of the strengthened systems. The observed failure modes, load-deflection relations, deflection profiles, and strain measurements were also studied. The tested beams showed a ductile behavior, with 15.1 and 22.2% enhancements in the yield and ultimate flexural capacities, respectively. Simplified empirical equations were developed to predict the ultimate load of the bolted HFRP–steel beams. ANSYS software was used to model the beams’ behavior and investigate the effects of the HFRP thickness, bolt spacing, steel grade, loading scheme, and beam length on the effectiveness of the adopted fastening technique. Increasing the HFRP length enhanced the utilization of HFRPs as well as the beam’s ductility, with a reduction of up to 51.2% in the mid-span deflection. Moreover, the strain compatibility of the HFRP–steel beams was improved with an 87.2% reduction in the interfacial slippage. The bolt arrangement showed an insignificant effect on the overall performance of the beams. The numerical results verified the effectiveness of the fastening technique in enhancing the flexural performance of the steel beams, with gains of up to 16.7% and 34.5% in the yield and ultimate load-carrying capacities, respectively.

“…These laminated structures can be classified according to their span-to-thickness ratio  as thin (slender), , and thick plates or shells, 10   [1]. Among this class of composites, thin laminated plates are widely used for various types of aerospace, marine, and civil structures due to their improved mechanical properties, i.e., long fatigue life [2][3], high strength [4][5], and superior corrosion resistance [6]. However, the thin laminated structures are susceptible to geometrically non-linear displacements due to harsh operating conditions, such as large deflections and/or buckling deformations.…”
