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 ...
Influence of crystallinity on interlaminar fracture toughness and impact properties of polyphenylene sulfide/carbon fiber laminates
(2021-01-01)
The crystallization behavior of thermoplastic matrix is considered as an important property which can highly affect for the mechanical and thermal properties of laminated composite structures. This manuscript aims to ...
Assessment of the interlaminar strength of resistance-welded PEI/carbon fibre composite
(2018-02-01)
This study has as its main objective to evaluate the effectiveness of the welding process by electrical resistance in a composite poly (ether-imide) matrix reinforced with continuous fibres of carbon, from the study of the ...

Processing, thermal and mechanical behaviour of PEI/MWCNT/carbon fiber nanostructured laminate
(2017-11-01)
In this work, nanostructured composites of polyetherimide (PEI) with addition of functionalized multiwall carbon nanotube (MWCNT) were processed via solution mixing. After processing, these nanocomposites were evaluated ...
The Role of Stitch Yarn on the Delamination Resistance in Non-crimp Fabric: Chemical and Physical Interpretation
(2017-03-01)
In a 3D preform, the out-of-plane reinforcement is effective for decelerating or suppressing the delamination process as the non-crimp fabric does not connect the neighboring laminae effectively. Hence, the interlaminar ...
Interlaminar crack onset in co-cured and co-bonded composite joints under mode I cyclic loading
(2019-03-01)
Composite joints exhibit different behavior in regard to delamination resistance when dealing with fatigue phenomenon. This research work focuses on an investigation to understand the failure mechanisms on the interfacial ...
Influence of environmental effect on thermal and mechanical properties of welded PPS/carbon fiber laminates
(2019-08-28)
This work consists in the evaluation of the influence of the environmental effects (ultraviolet radiation and humidity) on PPS/carbon fiber thermoplastic composite laminates integrated by electrical resistance welding. In ...
Hygrothermal effects on the shear properties of carbon fiber/epoxy composites
(Springer, 2006-11-01)
The environmental factors, such as humidity and temperature, can limit the applications of composites by deteriorating the mechanical properties over a period of time. Environmental factors play an important role during ...
