AGENCY USE ONLY (Leave blank)2. REPORT DATE 24.Jan.00 REPORT TYPE AND DATES COVERED THESIS TITLE AND SUBTITLE FATIGUE DAMAGE MECHANISMS OF ADVANCED HYBRID TITANIUM COMPOSITE LAMINATES AUTHOR(S)CAPT RHYMER DONALD W PERFORMING ORGANIZATION NAME(S) AND ADDRESS(ES)GEORGIA INSTITUTE OF TECHNOLOGY Comparing the number of cycles between the initial titanium ply damage and specimen failure showed a significant improvement (one order of magnitude for high cycle fatigue) in advanced HTCL due to interface strengthening. The damage progression following the initial ply damage (not performed on initial HTCL) demonstrated the effect of the strengthened PMC/titanium interface. Using acetate film replication of the specimen edges once titanium damage was evident, the advanced HTCL showed a propensity for some fibers in the adjacent PMC layers to fail at the point of titanium crack formation, suppressing delamination at the Ti/PMC interface. Following titanium ply cracking, these fibers would break and either a Mode I/Mode II (for outer ply damage) or Mode II (for inner ply damage) loading condition resulted in damage propagating longitudinally between the PMC fibers, rather then at the interface. The inspection of failure surfaces validated these findings, revealing PMC fibers to remain bonded to the majority of the titanium surfaces. SPONSORING/MONITORING AGENCY NAME(S) AND ADDRESS(ES)THETension compression fatigue (R = -0.2) was performed on both advanced and initial HTCL in this investigation and the strengthened interface was found superior in damage tolerance. Even though the fatigue lives were decreased for both HTCL constructions, the advanced HTCL endured a far greater number of cycles-to-failure following the initial titanium ply crack than initial HTCL at the same stress level due to resistance to delamination. Failure surfaces revealed a substantial amount of fibers xiv bonded to the titanium in advanced HTCL, while the initial laminate had few if any PMC fibers bonded. While overall fatigue life was not improved for either loading scenario,

Fatigue simulation for titanium/CFRP hybrid laminates using cohesive elements

“…This hybrid material also has a high resistance to impact and lightning strikes that fiber-reinforced plastic (FRP) laminates do not have [1]. In recent years, aerospace researchers have endeavored to develop FML with a titanium alloy face sheet for future high-speed aircraft because titanium has higher creep resistance than aluminum alloy [2][3][4].…”

Low velocity impact response of fibre-metal laminates – A review

“…But, the inter dependency of impact response by many other factors, a prior conclusion about magnesium based FML is still not yet clear [26,27]. Much research work has been published about Titanium (Ti) based FMLs for years [28][29][30][31][32]. During the low-velocity impact, the fracture of Ti layer on the non-impacted side plays a major role to predict the damage characterization of inner composite laminate [33].…”

Galvanic corrosion behaviour of carbon fibre reinforced polymer/magnesium alloys coupling

“…Normally, the densities of FMLs based on aluminium and titanium alloys sheets are about 2.29-3.66 g/cm 3 [2,3]. In order to further reduce the FMLs materials weight, many investigations were carried out by replacing the aluminium alloys with Mg-Al alloys (AZ31) [4,5], saving of around 24% materials weight.…”
