On September 13, SABIC, a world firm within the chemical business, launched a brand new novel carbon fibre-reinforced, flame-retardant compound at InnoTrans 2022 in Berlin. The corporate says that it’s well-suited for pellet-fed additive manufacturing (PFAM) that complies with E.U. and U.S. rail hearth security requirements.
SABIC hopes that the brand new compound, named LNP THERMOCOMP AM DC0041XA51, will assist the rail business advance from constructing conventional instruments for half manufacturing from thermosets to utilising on demand 3D printing. It goals to doubtlessly decrease system prices by lowering stock ranges of huge instruments and substitute elements.
At InnoTrans 2022, SABIC is exhibiting a big front-hatch half printed by CAF, a number one multinational provider of complete transit options for main railway networks, utilizing the brand new compound. CAF selected this compound with the goal of printing substitute elements rapidly and minimising lead occasions.
“With our elevated give attention to 3D printing, we have been searching for a fabric that complies with the stringent security necessities set forth in worldwide requirements like NFPA 130 or EN45545,” stated Lucas Esteban, operational supervisor from Digital Manufacturing, CAF.
Esteban continued: “SABIC’s LNP THERMOCOMP AM DC0041XA51 compound has distinctive options that match effectively with business necessities, together with the suitable railway certificates. Its non-halogenated flame-retardant system addresses present sustainability tendencies, and its carbon fibre reinforcement and beneficial processing enable us to make bigger half geometries with enough stiffness and restricted warpage.”
The brand new compound is without doubt one of the first PFAM-capable supplies to adjust to necessities of the harmonised European EN45545 customary (R1 Hazard Degree 3) and the U.S. NFPA-130 customary for inside and exterior elements. The product has been licensed compliant with each requirements by an unbiased laboratory.
The brand new materials gives vital efficiency benefits for printing giant elements utilizing PFAM. In keeping with SABIC, it maintains its structural integrity throughout printing and delivers good dimensional stability with low warpage for the completed half. The corporate states that it could remove the necessity for added funding because the product facilitates excessive printing speeds at comparatively average temperatures.
Potential different functions may embrace exterior elements corresponding to bumpers, inside cladding parts corresponding to facet panels, partition partitions and ducts, and seating backs and shells.
Luc Govaerts, director, Formulation and Utility Growth, Specialties Enterprise, SABIC, stated: “We developed our latest LNP THERMOCOMP AM compound to supply the rail business a regulation-compliant answer that can be utilized for on-demand printing of huge, advanced exterior and inside elements in comparatively small construct numbers.”
