Fibre reinforced lightweight tension rod system
A new combined join technology and an appropriate load transmission system to connect the GFRP (carbon fiber reinforced plastic) rods is presented. By means of this development a new optimized fibre-reinforced lightweight tension rod system for application in civil engineering is provided. The developed GFRP tension rod system consists of a GFRP rod and load transmission elements which are connected by the new combined join technology composed of a specially dimensioned pressing connection and adhesive bond. With this hybrid connection, the form closure and force closure of the pressing connection is supplemented by the strength of the adhesive bond. This is a purposeful interaction of different connection categories in one device junction. By means of this goal-oriented combination of connections, a new lightweight tension rod system with hybrid load transmissions with optimized mechanical properties can be provided. A tensile strength of about 350 MPa is possible with this new lightweight tension rod. In comparison to steel (S 235), the tensile strength of the GFRP tension rod system is about 20% higher. The new GFRP tension rods contribute significantly to a commercial, profitable manufacturing of a new generation of highly stressed complex lightweight structures. Furthermore, the developed tension rods for an application in supporting structures have a high innovation potential. But more investigations and analyses to utilise the potential of the new tension rods are the topic of further researches on the Professorship of Lightweight Structures and Polymer Technology. Especially the integration of textile sensors (new stitched wire sensors) is one of the further research projects. During the process of Pultrusion the new sensor system will be integrated in the matrix of resin and fibres. With the use of these integrated sensors a monitoring of the construction can be possible. The sensors detect extensions inside the tension rods. If the critical extension is exceeded, the sensor system gives a signal. This specific feature is very important in the case of overloading (snow), which can reduce the capacity to carry load, because the danger of collapse can be prognosticated. Thus is to prevent danger to human life.
