Mode II delamination of carbon-glass fiber/epoxy hybrid composite under fatigue loading
(Elsevier B.V., 2022-01-01)
This work proposes a mechanistic model to evaluate and characterize the mode II delamination of carbon-glass/ fiber hybrid composites under fatigue loading. To this aim, crack growth was investigated at microscopic and ...
Mode I and mode II delamination of carbon/glass/epoxy hybrid composite: A statistics-based analysis
(2021-01-01)
The delamination of a carbon/glass/epoxy hybrid composite was studied experimentally to analyze the effect of reinforcement heterogeneity on data dispersion. A statistical approach was applied to evaluate the effect of the ...
The relationship between pure delamination modes i and II on the crack growth rate process in cracked lap shear specimen (CLS) of 5 harness satin composites
(2015-11-10)
Carbon fiber reinforced polymers (CFRP) structure can include dropping-off plies in order to comply with design requirements aiming at significant weight savings. However this type of discontinuity represents a potential ...
Applicability of standard delamination tests (double cantilever beam and end notch flexure) for 5HS fabric-reinforced composites in weft-dominated surface
(2015-01-01)
Currently, the standard delamination tests established by ASTM (available for mode I and mix mode) are limited to unidirectional composites. Although some researchers have conducted delamination tests in woven composites, ...
FEA simulation and experimental validation of mode I and II delamination at the carbon/glass/epoxy hybrid interface: Physical-based interpretation
(2020-12-01)
The aim of this study was to carry out simulations and perform experimental quasi-static delamination tests in modes I and II to characterize the mechanical behavior at a hybrid interface. For that purpose, contact angle, ...
Fracture analysis in 5HS carbon composites subjected to pure modes I and II fatigue induced delamination
(2014-01-01)
Interlaminar fracture process in woven composite laminate in general takes place in a nonlinear front propagation when analyzing a 2-D propagation for mode I opening. The nonlinearity is justified by the arresting crack ...
Fadiga em compósitos 5HS carbono/epóxi processados via RTM: relação entre cargas axiais no plano e modos de delaminação
(Universidade Estadual Paulista (Unesp), 2015-02-11)
Carbon fiber composite materials are currently widely employed in air transportation as structural components in Boeing 787 Dreamliner, which has around 80% (v/v) in composite. However these materials are susceptible to ...

The Influence of Matrix Chemical Structure on the Mode I and II Interlaminar Fracture Toughness of Glass-Fiber/Epoxy Composites
(John Wiley & Sons Inc, 2003-07)
The present paper is concerned with Mode I and Mode II delamination tests performed on three different glass fiber reinforced epoxy composites, chosen to obtain different final structures. The effect of crosshead speed on ...
