Ranges marked “confirmed per grade” are set by reinforcement and resin selection; send us your target specification and we confirm what we can supply.
What chopped carbon actually does in a compound
Short fibre changes three things at once: stiffness, electrical conductivity and dimensional stability. That combination is why it appears in parts that must hold tolerance or dissipate static rather than parts that must carry a bending load. Where strength governs, continuous fibre is the correct answer and chopped material will not substitute for it.
纤维长度如何改变结果
Length is a trade-off, not a quality scale. Short lengths (3 mm) disperse more evenly and feed more reliably, which matters in thin walls and small gates. Longer lengths (12 mm and above) buy more reinforcement per fibre but are harder to disperse and more likely to break down in the screw. The right length is set by the wall thickness, the gate and the moulding process.
上浆剂不是细节
Sizing decides whether the fibre bonds to the resin at all. A size matched to an epoxy will not perform the same way in a polypropylene carrier, and an unsized product is normally chosen when the customer applies their own coupling system. Tell us the carrier resin when you enquire; it is the single most useful piece of information after the fibre length.
Where it fits
SMC and BMC, injection moulding and compression moulding are the usual routes. It is also used to adjust an existing compound rather than to build a part from scratch. Compare with carbon nanotubes when conductivity is the only target, and with carbon fiber tows when the part needs continuous reinforcement. Send the carrier resin, length and target loading through contact.
