A New Hybrid Material of Textile Reinforced Concrete and Glass Fibre Reinforced Plastic

摘要

A new high-performance hybrid material has been developed by the combination of textile reinforced concrete (TRC) and glass-fibre reinforced plastic (GFRP). So, advantages of both materials, namely high strength, durability, surface quality and cost-efficient production can be implemented in one hybrid material. Both materials, TRC and GFRP, have been developed and optimized separately from each other with an emphasis on the adjustment of different mechanical and physical characteristic of both materials. Nevertheless, the adaptation of both components together was limited. According to this finding, the integration of an interlayer for the mechanical and thermal decoupling was indispensable. The developed interlayer, consisting of an epoxy resin and a polyester nonwoven, guarantees a high and sustainable detention compound between GFRP and TRC. The new GFRP-TRC-hybrid material has a tensile strength of 165 MPa and a density of 1.65 g/cm~3. With this composite, consisting of 5 mm TRC and 3 mm GRP, the double curved research pavilion "CoFigloo" was produced.
