Tout ce que vous devez savoir sur le filament de fibre de carbone
Carbon fiber is made of a long chain of carbon atoms bonded together. The chain is usually between 5 to 10 micrometers in diameter and varies in length according to the application. Over the years, carbon fiber has become popular across many sectors because it offers interesting properties, including high stiffness, high tensile strength, low weight, high chemical resistance, high temperature tolerance and low thermal expansion. Pure carbon fiber is actually five-times stronger than steel and twice as stiff, yet lighter. As you can imagine, these characteristics make carbon fibers suitable for applications that rely on a material’s properties to optimize performance, which is particularly the case in sectors such as aerospace, automotive, military or civil engineering for example.

As some of you may already know, carbon fibers are rarely used on their own. They are usually combined with other materials to form what we call a composite material – referred to as carbon fiber reinforced materials in this particular case. These composites are made of a matrix material, usually a polymer – even though it is possible to use non-polymer materials such as ceramics – to which carbon fibers are added. The main benefit is you end up with a stronger, yet lighter plastic with an increased level of stiffness.
Filament de fibre de carbone
Le filament de fibre de carbone utilise des fibres de carbone courtes, composées de segments de moins d’un millimètre de long, qui sont mélangés à un thermoplastique connu sous le nom de matériau de base. Il existe un certain nombre de filaments populaires qui peuvent être achetés avec un remplissage en fibre de carbone, notamment le PLA, le nylon PETG, l’ABS et le polycarbonate. Songhu a développé des filaments en fibre de carbone pour des applications plus techniques. tels que le filament de fibre de carbone PLA, le filament de fibre de carbone PETG, les filaments PEEK en fibre de carbone et le filament PEKK en fibre de carbone, etc. Ces fibres étant extrêmement résistantes, elles font augmenter la résistance et la rigidité du filament, et réduisent également son poids total.
