Straight pultruded carbon fiber strips, rods and tubes for an RC model parts supplier in the USA
A US supplier of radio-controlled model parts buys 3K roll-wrapped tubes and pultruded tubes, rods and strips from us. Its key requirement: a strip laid flat on a table must stay perfectly straight, with no banana-shaped bow.
The challenge
In RC models, thin carbon strips and rods are used as spars, stiffeners and push rods, where a bowed part is not usable. The customer’s acceptance test is simple and strict: lay the strip flat on a table, and it must not curve into a banana shape or drift off a straight line.
What we supply
One order combines four product types: 3K roll-wrapped tubes from 8 mm to 20 mm outside diameter, small pultruded tubes, pultruded rods from 2.5 mm to 6 mm, and thin pultruded strips down to 0.6 mm thick, all cut to 1000 mm. The full size list is in the table below.

| 3K carbon fiber tubes (OD × ID × length) | 8 × 6, 12 × 10, 14 × 12, 16 × 14, 18 × 16 and 20 × 18 × 1000 mm, among others |
