Carbon Fibre Reinforced Plastics

Timber structure is the mainstream method of ancient Chinese architecture. However due to the effect of weathering and long history, it was badly damaged. Therefore, the protective repairing is imminent. The traditional reinforcement method of pier columns strengthened with iron sheet presents unsatisfactory performance in recovering the bearing capacity, and the study on Carbon Fibre Reinforced Plastics (CFRP) material applying in strengthening pier column is relatively lacking. This paper studied the mechanical properties of 20 timber columns, 17 of which used the CFRP for reinforcement, and one specimen is strengthened with iron sheet. With the maximum bearing capacity of reinforcement columns with CFRP recovering up to 103.22%, the research proves reasonable arrangement of CFRP hoops and suitable strengthening quantity of CFRP could get commendable reinforcement results. Finally, considering the effect of the pier type on the bearing capacity of pier columns, this paper puts forward a more accurate and universal formula compared to Su model, which provides theoretical foundation for restoration projects of ancient architecture.

Carbon Fibre Reinforced Plastics

A steadily increasing application of fibre-reinforced plastics in the field of lightweight construction has been observed in the course of the past two decades. Currently a major challenge in the growing high technology market is the quality assurance of manufactured fibre-reinforced plastic components. During different stages in the manufacturing process of fibre-reinforced plastics, defects of different types and sizes are enclosed in them, exerting a destructive influence on the performance of fibre-reinforced plastics in various practical applications in terms of strength, stiffness and brittleness. Thus the aim of this research project was to investigate the effect of defined local defects on the mechanical properties, such as tensile, flexural and impact properties, of fibre-reinforced plastics, in particular carbon fibre-reinforced plastics. Results show that these mechanical properties depend significantly on the type and size of defect.

Carbon Fibre Reinforced Plastics

A load dependent and curvilinear respectively variable-axial fibre design can notably enhance the strength and stiffness of lightweight components compared to fibre reinforced structures made of common multiaxial fibre textiles. At the Leibniz-Institut für Polymerforschung Dresden e. V. (IPF) special design strategies are in the focus of current studies. Two currently developed components made of carbon fibre reinforced plastics, a lightweight three-legged stool and a lightweight recurve bow riser, are described within this paper.
