Custom Composite Tubes
Manufacturing Custom composite tubes
Hollow composite structures can be difficult to manufacture. This is because pressure must be applied to both the inside and outside of the laminate. Carbon fiber tubes with continuous profiles are usually manufactured by pultrusion or filament winding.
Pultruded tubes are by far the most cost-effective method for manufacturing continuous composite profiles. When pultruding hollow tubes, a "floating mandrel" is required. The chrome steel rod is firmly fixed to the side of the die where the material enters. The distance of the mounting hardware is far enough away that it will not interfere with the impregnated fiber as it enters the die.
The space between the mandrel and the die will determine the wall thickness of the carbon fiber tube.Pultruded carbon fiber tubes can produce tubes of almost any length. The transportation of tubes is usually limited by length. In pultrusion, most of the fibers will extend in the direction of the tube. This creates a tube with great stiffness, but not much hoop or transverse strength.
General process flowte
Preparation
This stage includes material selection and preparation. Carbon fiber prepreg is usually carbon fiber yarn that has been impregnated with resin beforehand for subsequent winding. It is also necessary to prepare the mold, usually a metal or composite mold so that the carbon fiber can be wound on it.
Fiber winding
In this stage, the carbon fiber yarn is wound on the mold to form a tubular structure. This process generally involves two main winding methods: axial winding and hoop winding. Axial winding is to wind the carbon fiber parallel to the axis of the tube, while hoop winding is to wind the carbon fiber around the axis of the tube at different angles to increase strength and stiffness.
Curing
After winding, the tube needs to be cured. This usually involves heating the tube to cure the resin. The temperature and time vary depending on the type of resin used and the process specifications.
Post-processing
After curing, the tube may need post-processing such as trimming, cutting, and grinding to meet the final specifications and surface quality requirements.
Inspection and testing
The finished tube usually needs to undergo quality control and testing to ensure that it meets the required strength, stiffness, and other performance indicators.
Application
The finished carbon fiber winding tube can be used in various applications such as aerospace, automotive engineering, sports equipment, etc.
The main use of Custom composite tubes are to be used as a reinforcing material to be compounded with resin, metal, ceramic, and carbon to manufacture advanced composite materials. Carbon fiber-reinforced epoxy resin composite materials have the highest specific strength and specific modulus among existing engineering materials.
