Co-curing bonding of carbon fibre/epoxy composite joints with excellent structure integrity using carbon fibre/PEEK tapes
نویسندگان
چکیده
A novel co-curing process was proposed for the bonding of carbon fibre/epoxy composites by replacing traditional epoxy adhesives with fibre/PEEK (CF/PEEK) tapes, an attempt to improve structure integrity. The lap-shear strengths, fatigue resistance and mode-I mode-II fracture behaviour co-cured joints at 22 °C 130 were investigated, failure mechanisms also studied. experimental results demonstrated that, aerospace structural adhesive surface-treated CF/PEEK tapes composite joints, strength had been increased 47% 68% °C, respectively; life extended 3.39 times; energy 70% 182% 59% 54% respectively. An analysis on surfaces tested specimens proved significant plastic deformation breakage PEEK resin extensive fibre delamination being main bonded joints. Overall, this study a huge potential film significantly enhanced integrity thermal stability.

Carbon nanotube-based synthetic gecko tapes.
We have developed a synthetic gecko tape by transferring micropatterned carbon nanotube arrays onto flexible polymer tape based on the hierarchical structure found on the foot of a gecko lizard. The gecko tape can support a shear stress (36 N/cm(2)) nearly four times higher than the gecko foot and sticks to a variety of surfaces, including Teflon. Both the micrometer-size setae (replicated by n...
متن کاملExcellent Temperature Performance of Spherical LiFePO4/C Composites Modified with Composite Carbon and Metal Oxides
Nanosized spherical LiFePO4/C composite was synthesized from nanosized spherical FePO4 ·2H2O, Li2C2O4, aluminum oxide, titanium oxide, oxalic acid, and sucrose by binary sintering process. The phases and morphologies of LiFePO4/C were characterized using SEM, TEM, CV, EIS, EDS, and EDX as well as charging and discharging measurements. The results showed that the as-prepared LiFePO4/C composite ...
