Fused filament fabrication (FFF) is the most popular additive manufacturing method, which allows production of highly complex three-dimensional parts with minimal material waste. On other hand, polyethylene terephthalate glycol (PETG) has been used to replace traditional polymers for 3D printing due its chemical resistance and mechanical performance, among benefits. However, when fibres are added, these PETG-based composites can be suitable many different applications. Nevertheless,...
The development of new adhesives has allowed to expand the application bonding into most diverse industrial fields. This review article presents commonly used experimental methods for investigation mechanical performance adhesively bonded joints in aerospace, wind energy, automotive and civil engineering sectors. In these sectors, due their excellent intrinsic properties, composite materials are often along with conventional such as steel, concrete aluminium. this context, limitations that...
This work aims to optimize the physicochemical and tensile properties of vascular fibers extracted from a local date palm rachis in Algeria. fiber has very specific composition architecture is different remaining obtained six possible parts tree. For this purpose, Taguchi orthogonal array design L16 was applied reduce number experiments. The were with two methods (boiling retting water) treated by NaOH various concentrations (1%, 2%, 3%, 5%) for durations (1, 4, 8, 12 h). They characterized...
It is known that 3D-printed PETG composites reinforced with carbon or Kevlar fibres are materials can be suitable for specific applications in the aeronautical and/or automotive sector. However, this purpose, it necessary to understand their mechanical behaviour, which not yet fully understood terms of compression. Therefore, study intends increase knowledge domain, especially static as well regard creep and stress relaxation due inherent viscoelasticity matrix. In context, static, tests...
This study aims to analyse the annealing effect on mechanical properties of PETG, carbon fibre reinforced PETG (PETG + CF) and Kevlar KF). Regardless material, final dimensions vary with temperature exposure time, showing that addition fibres had no significant influence. On other hand, presence affects radius curvature, but this parameter shows be very dependent type fibre. In terms hardness, higher temperatures times generally lead values, achieving improvements about 20% over untreated...
ABSTRACT The self‐heating effect occurring during fatigue loading of polymer‐matrix composites remains to be a significant problem due its role in accelerating structural lifespan degradation. This is especially challenging when accelerated tests are applied at very high‐frequency regimes since without cooling the tested structure dominated by this phenomenon and rapidly reaching critical temperature value, finally fails prematurely. study reviews approaches reduce through modification...
Fiber-reinforced composites are gradually replacing the traditional materials in many engineering applications. However, for applications these still unsuitable, due to their lack of toughness. In this context, hybridization is a promising strategy which two or more types fiber combined obtain better balance mechanical properties compared non-hybrid composites. Therefore, main goal work study effect on static performance and interlaminar shear strength. For purpose, carbon, glass, Kevlar...
Nowadays, composite materials are increasingly used in the most diverse areas of engineering, where non-planar geometries begin to be quite frequent. However, existing knowledge about its mechanical performance is still not enough for structural applications. Therefore, experimental tests were carried out study thickness effect on static compression and multi-impact response laminated E-glass/Polyester semicylindrical shells. For this purpose, specimen with thicknesses 1.1 mm, 1.6 mm 2.1...
