Failure of carbon composite-to-aluminum joints with combined mechanical fastening and adhesive bonding

Effect of Motoring Voltage on Compression Ratio of a Free-Piston Linear Generator Engine

“…The world energy demand will increase by 36% from 2008 to 2035 [1,2]. However, the growing energy demand from fossil fuels has increased CO 2 emissions exponentially from nearly zero in 1870 to over 32 GtCO 2 in 2011.…”

Experimental and Theoretical Studies of the Secondary Bending of the Bonded Composite Butt Joints in Tension

“…[6][7][8] In this configuration, the joint inner overlap edge will experience much greater bending moments than the outer overlap end when the joint is loaded in tension as a result of secondary bending. 9 A recent survey of open literature on bonded composite joints, 2,4,[8][9][10][11][12][13][14] showed that: (i) limited experimental data is available on bonded butt joint configurations in tension; 14 (ii) a theoretical analysis of laminated composite beams in bending has not been carried out simultaneously for both plane strain and plane stress conditions; 9,10,[15][16][17] (iii) the difference between parameters such as the effective Young's modulus, bending stiffness and the obtained strains induced by these two conditions has not been studied 9,10,[15][16][17] and (iv) no papers were found that theoretically estimate the strain at the overlap end region.…”

“…As such, joints with high modulus, high strength adhesives have the potential to have much higher static strengths than bolted joints. 4 To supplement adhesive bonding, additional mechanical fasteners can be introduced to enhance structural integrity using a hybrid (bonded and bolted) attachment approach. In order to use this approach, understanding the deformation behaviour of the bonded butt joints is essential.…”

“…Quasi-isotropic laminated composite panels are usually used in aircraft applications, [1][2][3][4] since these types of layups maintain satisfactory strength in both longitudinal and hoop directions. A recent high-profile example of the rapid expansion of the use of composites in commercial aircraft is the Boeing 787, which includes composite fuselage barrel sections as large as 6 m in diameter and 15 m long.…”
