The purpose of the present study was to characterize delamination fracture continuous carbon fiber/epoxy multidirectional-laminates under Mode I, II and Mixed-Mode I/II loading conditions. considers variation interlaminar failure energy, G C , with extent crack jumping, ensuing fiber bridging, which arises during growth in various modes loading. main type laminate studied a multidirectional composite prepared from 24 ply lay-ups (-45°/0°/+45°) 2S (+45°/0°/-45°) 2S. initial located at...
The effect of bond thickness on the fracture toughness adhesive joints was investigated from a microstructural perspective, using compact tension (CT) adhesive-joint specimens with different thicknesses. material rubber-modified epoxy resin 12.5 wt% carboxy-terminated butadiene acrylonitrile (CTBN) elastomer. shapes rubber particles dispersed in layers damaged and undamaged were observed an optical microscope. damage distributed along interfaces between layer two adherends. results show that...
The effect of surface treatment aluminum on the bonding characteristics aluminum- CFRP (carbon fiber reinforced plastic) composite joints has been investigated. panel was treated by DC plasma. plasma carried out at different times and volume ratios acetylene gas to nitrogen gas. used were 1 : 9, 3 7, 5 5, 7 3, 9 1. 10, 20, 30, 40, 50, 60 s. Optimal conditions determined measuring T-peel strength water contact angle as functions time ratio. Single lap shear tests performed using...
Adhesion strength between epoxy resin and carbon fiber was analyzed using various microbond types adhered onto a single fiber. Experimental pull-out tests were performed for quasi-disk type, hemispherical type droplet specimen. The specimen showed high regression coefficient low standard deviation in the measurement of interfacial shear data as compared with ones. Average value about 55% large those other types. Finite element analysis that stress distributions along interface did not have...
The paper presents an overview of the present state study on fatigue behaviors at very high number cycles (<TEX>$N_f$</TEX> > <TEX>$10^7$</TEX>). A classification materials with typical S-N curves and influencing factors such as notches, residual stresses, temperatures, corrosion environments stress ratios are given. microstructural inhomogeneities micro-cracks played important roles in cycle behaviors. failure mechanisms for design components mentioned.
