Evaluation of interfacial strength in CF/epoxies using FEM and in-situ experiments

Influence of the Matrix Type on the Mode I Fracture of Carbon-Epoxy Composites Under Dynamic Delamination

“…Hobbiebrunken et al [12] have made theoretical studies with the same objectives, Stevanovis et al [13] used a mixture of vinylester resin and ABS as intermediate layers between laminae of a composite with glass fiber and vinylester looking for an increase of delamination strength. Hojo et al [14] studied the delamination in mode I of two composites carbon/epoxy, but using as interlayer two different thermoplastic materials which has an important influence in delamination.…”

Numerical homogenization of cracking processes in thin fibre-epoxy layers

“…In addition, instead of simulating the microscale fracture processes in an averaged, smeared fashion using a continuum damage model, a cohesive zone model is applied. This is, since experimental observations show that the microscale failure behaviour of relatively brittle fibre-epoxy systems is characterised by fibre decohesion and matrix cracking along well-identifiable, discrete cracking paths [12,13,14].…”

SEM <I>In Situ</I> Study on Deformation Behavior of Cu and Cu/Ni Films under Three-Point Bending

“…[10][11][12][13] Previous theoretical investigations pointed out that the failure in film/substrate structure was mainly caused by the mismatch of thermal expansion coefficient and elastic properties between bonded layers at the interface. [14][15][16][17] However, few experimental studies were carried out to investigate the failure characteristics of metallic films/substrate with small size scale. This paper focuses on SEM in situ observation of the metallic films under three-point bending in order to reveal the failure mechanism of metallic film/substrate structure.…”
