Introduction to Laminated Tubing
Laminated tubing is constructed from thermosetting resins like Phenolic and Epoxy and is integrated with base materials such as cellulose paper, woven cotton cloth, or glass cloth. It transforms into a dense, uniform material through intricate winding under intense pressure and heat.
This material can be easily worked upon – it’s suitable for machining, polishing, painting, and other manipulation. Using standard tools, laminated tubing can be effortlessly cut, drilled, tapped, threaded, and punched. It boasts outstanding electrical insulation properties. It is lighter, more robust, and often more cost-effective than metal.
Composition and Manufacturing of Laminated Tubing
Materials
Laminated tubes are made using a combination of materials, each selected for specific properties to enhance the tube’s functionality. The typical composition includes:
- Phenolic: Known for its high mechanical strength and heat resistance, Phenolic is used in laminated tubes to enhance durability and maintain structural integrity under high temperatures. This material is beneficial for tubes required to withstand harsh environments.
- Epoxy: Epoxy resins are utilized for their exceptional adhesive properties and chemical resistance. Epoxy adds a robust, protective layer in laminated tubes that is resistant to chemical degradation and a strong barrier against moisture and corrosive substances.
The choice of materials hinges on balancing flexibility, barrier efficiency, and content compatibility.
Manufacturing Process
As mentioned, laminated tubing begins with selecting thermosetting resins like phenolic and epoxy.
These resins are known for their robustness and are combined with base materials like paper, canvas, linen, or glass cloth to enhance the tube’s properties.
The chosen materials are then convolutely wound together under high pressure and heat. This process binds them into a dense, homogeneous material with high structural integrity and the versatility to be further processed.
