“…However, the lower strength of the cylindrical-pinned joints may be also influenced by the lower density of the pins ( Figure 23 ). Xiong et al investigated the effect of composite orientation on the mechanical properties of the pin joints [ 76 ]. Carbon fabric reinforced epoxy composite was joined with titanium alloy component with protruding wedge-like protrusions similar as in the previous works [ 67 , 68 ].…”

“…The specimens were tested in single lap shear experiments. With the increase of the ±45° plies content the failure mechanism changed from the composite matrix crushing to the combination of the bending, the fracture of pins and composite compression [ 76 ]. With optimum composite orientation (55.6% of 45° plies), the joints damage initiation load was increased by 24.84% and the joint ultimate failure load was increased by 134.5% compared to the reference specimens without protrusions [ 76 ].…”

As fiber reinforced plastic composites gain an increasingly larger share in aerospace structures, the problem of joining them with metal elements becomes significant. The current paper is the second part of the literature review, which gathers and evaluates knowledge about methods suitable for the mechanical joining of composite and metal elements. This paper reviews the joining methods other than bolted joining, which are discussed in the first part of the review, namely self-piercing riveting, friction riveting, clinching, non-adhesive form-locked joints, pin joints, and loop joints. Some of those methods are full-fledged and employed in commercial applications, whereas others are merely ideas tested at the level of specimens. The current review describes the ideas and the qualities of the joining methods as well as the experimental work carried out so far. The summary section of this paper contains a comparison of those methods with the reference to their qualities, which is important from the point of view of a composite structure designer: possibility of the joint disassembly, damages induced in composite, complication level, weight penalty, range of possible materials to be joined, and the joint strength.

“…After joint failure, 6 plies (1.5mm thickness of composite) remained attached to the metal, with the pin height being 1.2mm. In 2015, Xiong et al (22) performed testing of Comeld™ pinned lap joints and observed the effect of composite ply orientation on the mechanical properties of the joints. Results showed that optimal performance in terms of damage initiation load, strength, maximum displacement and energy absorption result when the ratio of ±45° plies was approximately 50%.…”

“…Concerning the group of the "bulk" hybrid composites, Fu et al [4], Xiong et al [5], Dong [6], Qi et al [7], Isa et al [8] showed dependencies of composites' mechanical properties on fiber type, its volume fraction, as well as orientation angle. Song [9] revealed the difference in mechanical properties comparing different hybrid laminates.…”

This paper aims at experimental research of the effect of hybrid interface (carbon/glass fibers) on delamination resistance in unidirectional fiber reinforced polymer (FRP) composite laminates under the mode I opening load conditions. Three group of laminates exhibiting different combinations of reinforcing materials at delamination plane were tested. Critical strain energy release rates were determined by using the double cantilever beam (DCB) tests in accordance with the ASTM D5528 Standard. Values of the G IC were calculated by using classical data reduction schemes and they were compared with values obtained by using an alternative compliance based beam method (CBBM). For precise detection of delamination onset all tests were additionally supported by registration of the acoustic emission (AE) signal. Contribution of mixed-modes were evaluated by using numerical finite element analysis. Obtained outcomes revealed, that differences in the mode I c-SERR values obtained by using four different methods were insignificant. Moreover, the greatest value of the G IC was determined for laminates with hybrid interface and it was equal 0.24 N/mm.
