Carbon fibre rods are made with pultrusion (a heating process similar to extrusion) that has many advantages – the primary one being high stiffness and axial strength plus greater OD (outer diameter) tolerance. However, the rods are not suitable for high torque/load-bearing applications due to their fibre orientation. The most common uses of carbon fibre rods include remote control/model vehicles such as helicopters & RC boats, medical devices, sports equipment, robotics, construction, and architecture. But regardless of the purpose, buyers must keep some features in mind – and this guide will help them make an informed choice.
Go with Pure Carbon Fibre Rods
Although unlikely, some carbon fibre rods can be mixed with other materials or metal alloys, but that can negatively impact the rod’s quality. So, buyers need to make sure they go for one hundred per cent pure carbon fibre rods for better results. Similarly, one should ensure the rods have excellent corrosion resistance for prolonged use and longer service life. Moreover, high tensile strength, stiffness, low weight, chemical resistance, good temperature tolerance, exceptional load-bearing & stable performance, and low thermal expansion rates are also essential qualities to look for in carbon fibre rods.
Select an Appropriate Size
Since carbon fibre rods are manufactured using pultrusion, there is more flexibility as far as the length is concerned – which is why buyers will find carbon fibre rods available in numerous sizes. The choice only depends on the application or requirement at hand, but buyers should check both the diameter and the length to avoid any last-minute replacements or exchange. For instance, if you are using carbon fibre rods for remote control models, going with a smaller/medium size will be better as the rods are quite stiff and do not deform easily.
What More Should Buyers Keep in Check?
Before deciding on a particular carbon fibre rod, it is better to check if the rod is suitable for the desired application for hassle-free and quick installation or assembly. One should ensure the rods have a lightweight and smooth construction and if preferred, a buyer can look for rods with a surface finish or colour – especially if using them for decorative purposes. Lastly, buyers must check the reviews and feedback provided by other customers to select branded/high-quality carbon fibre rods.
