Interfacial adhesion quality in 3D printed continuous CF/PA6 composites at filament/matrix and interlaminar scales

چکیده
Fused deposition modelling (FDM) is a promising additive manufacturing technology for the fabrication of continuous fibre reinforced thermoplastic composites. However, major concern performance interfacial bonding in these The aim this study to evaluate interface quality 3D printed carbon/PA6 composite at two scales: filament/matrix scale and interlaminar one. Two different types samples were made: monofilament composites performing fragmentation tests, double cantilever beam (DCB) realising mode I fracture tests. After measuring strength individual carbon filament, fragment lengths observed by micro-CT measured order calculate shear (IFSS). DCB tests allowed determination toughness (GIc) 0°//0° +45°//-45° interfaces. obtained results are such

متن کاملFiber Line Optimization in Single Ply for 3D Printed Composites
In conventional manufacturing processes of composites, Carbon Fibre Reinforced Plastic (CFRP) laminates have been made by stacking unidirectional or woven prepreg sheets. Recently, as a manufacturing process of CFRP, 3D printing of CFRP composites has been developed. The 3D printing process of CFRP composites enables us to fabricate CFRP laminates with arbitrary curvilinear fibre plies. This in...

Introduction: Micro perforated panel (MPP) absorbents promise the next generation of sound absorbers as they have significant advantages over other porous adsorbents. In this study, we will investigate the acoustic performance of MPP absorbents made of biodegradable polylactic acid composite reinforced with natural corkwood fibers (PLA/Corkwood) by 3D printing technology. Material and Methods:...
متن کاملInterfacial effects in composites
It is well known that the behavior of diverse multicomponent systems such as fibrous composites, particle—filled polymers, polymer blends, and pigmented coatings depends not only on the composition, morphology, and properties of the constituents, but also on the nature of the interfacial region. This paper reviews typical examples, with emphasis on interpretation of interactions between constit...
متن کاملMicrowave dielectric characterisation of 3D-printed BaTiO3/ABS polymer composites
3D printing is used extensively in product prototyping and continues to emerge as a viable option for the direct manufacture of final parts. It is known that dielectric materials with relatively high real permittivity-which are required in important technology sectors such as electronics and communications-may be 3D printed using a variety of techniques. Among these, the fused deposition of pol...
