However, after the hype of the last couple of years,many realized that the industry is still focusing on prototyping and mould making rather than manufacturing functional end-use parts. There are various reasons for this holdup, but one of the major weaknesses is the low mechanical performance of the plastic material itself, and especially of the interfaces between layers. Note de contenu : - 3D printing with continuous carbon fibre - True3D process - Geometric, aesthetic, and structural challenges - From prototyping to manufacturing - Different printing parameters - Fig. 1 : Example of True3D path on a chain stay - Fig. 2 : Arevo design software workflow - Fig. 3 : Left: Specific tensile modulus of a unidirectional layup in comparaison to typical mental bike frame materials; Right: Cross-section of the CF-PEEK filament with a 50 vol% fibre volume cintent and void content <1% - Fig. 4 : Optimized material thicknesses - Fig. 5 : Analysis results for a frame subkect to a 2000N vertical seat load - Fig. 6 : Top: Schematic of the printing process including compaction roller and heat input in the form of a laser light - the incident angle of the laser to the substrate or incoming filament, and therefore the absorption, changes; Bottom: Absorption of the laser at different wavelenghts and fibre volume contents as a function of incident angle, which results in less or more heating - Fig. 7 : Arevo's first 3D printed carbon fibre bike En ligne : https://drive.google.com/file/d/1g3RNqoQPWkI_0esUBTTaD-Bzbt3t_WHG/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=31741 [article]
