“…This phenomenon may result from the greater ability of these laminates to accumulate energy (due to a greater proportion of metal in the process of energy transfer through the indenter), which results in greater capacity for faster laminate return to the elastic range after reaching its maximum deflection. The authors of other papers also reached similar conclusions about the capacity to accumulate energy demonstrated by FML laminates, including laminates based on titanium [4,9,14,[32][33][34][35].…”

“…This also corresponds to the conclusions stemming from the f-t curve analysis for higher impact energies (30 and 45 J) of HTCL. Figure 6 shows the relationship between the value of absorbed energy and the metal volume fraction parameter of the HTCL laminate for impact energies in the range of 5 to 45 J. level of energy absorbed by the laminate in the range of higher impact energy directly indicates a significantly greater share of laminate structure degradation (including even the share of local fiber cracking) that can be attributed to taking on a significant share in the energy absorption process (fiber dominant damage mechanism) [35]. This also corresponds to the conclusions stemming from the f-t curve analysis for higher impact energies (30 and 45 J) of HTCL.…”

The purpose of the work was the effect of metal volume fraction of fiber metal laminates on damage after dynamic loads based upon the example of innovative hybrid titanium–carbon composite laminates. The subject of the study was metal–fiber hybrid titanium–carbon composite laminates. Four types of hybrid titanium–carbon laminates were designed with various metal volume fraction coefficient but constant thickness. Based on the results, it can be stated that changes in the metal volume fraction coefficient in the range of 0.375–0.6 in constant thickness titanium–carbon composite laminates do not significantly affect their resistance to impacts in the energy range of 5–45 J. It was concluded that there were no significant differences in maximum force values, total contact time, and damage range. Some tendency towards a reduction in the energy accumulation capacity was observed with an increase in thickness of the metal part in relation to the total thickness of the laminate, especially in the lower impact energy range. This can result in the lower bending stiffness of laminates with lower metal content and potential elastic strain of the composite part before the initiation of the fiber damage process.

“…It has been found that it is possible to anticipate the increment of these values owing to clear almost linear trend of maximum force increment related to impact energy in energy range under test. Similar trends have been indicated in other studies describing impacts in conventional composites and FML laminates containing aluminium [25].…”

“…The research carried out by the authors and others [23,25,26] indicate that the layout of fibres in FML laminates and composites may have influence on degree of their degradation as a result of impacts due to their properties anisotropy (mainly in case of Young modulus) in individual composite layers. However, it is required to carry out further thorough research in this scope.…”

Fibre metal laminates (FML) are the modern hybrid materials with potential wide range of applications in aerospace technology due to their excellent mechanical properties (particularly fatigue strength, resistance to impacts) and also excellent corrosion resistance. The study describes the resistance to low velocity impacts in Ti/CFRP laminates. Tested laminates were produced in autoclave process. The laminates were characterized in terms of their response to impacts in specified energy range (5J, 10J, 20J). The tests were performed in accordance with ASTM D7137 standard. The laminates were subjected to impacts by means of hemispherical impactor with diameter of 12,7 mm. The following values have been determined: impact force vs. time, maximum force and the force at which the material destruction process commences (Pi). It has been found that fibre titanium laminates are characterized by high resistance to impacts. This feature is associated with elasto-plastic properties of metal and high rigidity of epoxy -fibre composite. It has been observed that Ti/CFRP laminates are characterized by more instable force during impact in stage of stabilization of impactor-laminate system and stage of force growth that glass fibre laminates. It has been observed more stable force decrease in stage of stress relaxation and withdrawal of the impactor. In energy range under test, the laminates based on titanium with glass and carbon fibres reinforcement demonstrate similar and high resistance to low-velocity impact, measured by means of failure initiation force and impact maximum force.

“…Low energy impacts can cause a complex net of matrix cracking and delaminations inside a composite, which can decrease its strength and durability. The danger of such damage is that in most cases they are invisible on the surface and cannot be detected during visual inspections of the structure, hence they are often called Barely Visible Impact Damage (BVID) [1][2][3][4][5].…”
