New Potentials of Lightweight Structures for Pipe Extrusion Products – Appliances of Reinforcements from short to endless Fibers

 

Prof. Dr. Jens Liebhold,

Papers # 2016 Berlin

To take the advantages of the excellent properties of fiber-reinforced components even more economically and industrially, new ideas to implement these potentials are in demand. Only with the introduction of fibers in a plastic matrix, the elastic behavior is changed towards to higher stiffness, strength and impact strength and thus improves the component properties. 

The specificity and the degree of innovation in the production of endless reinforced components is, opposite to injection molding and RTM processes, the uniform incorporation of endless fibers into a polymer matrix at a continuous extrusion process. A subsequent process step by injection molding allows the production of large-series components with high functional integration. 

For infrastructure purposes, especially in the area of pipelines used in the oil and gas industry, the RTP system has been introduced to become displace more and more conventional steel pipes due to better properties in the area of corrosion resistance, flexible design and speed of installation. One of the production possibilities is the Tape Winding Technology with highly automated process for the manufacture of load-carrying structures made of continuous fiber-reinforced plastic pipes with extraordinary mechanical, physical and chemical properties.
