Electrospinning Machine | Flexible cement fibers with high toughness and water- activated setting behaviorfor construction

Challenge: Brittle fracture and easy cracking pose significant challenges to the toughening and processing of cement-based composites. 

Method: Academician Xu Weilin's team at Wuhan Textile University implemented a cellulose-assisted wet spinning strategy to implant cement particles in situ into a porous cellulose matrix, achieving continuous large-scale preparation of cement-based fibers. Subsequent hydration induces in situ formation of a rigid continuous network interconnected with the flexible porous cellulose skeleton, thus forming an interpenetrating dual-network structure in cellulose-supported cement (CSC) fibers. 

Innovation 1: This structure simultaneously provides mechanical strength and toughness. Furthermore, the obtained CSC fibers demonstrate hydration manufacturability and can be woven into fabrics. 

Innovation 2: CSC fiber fabrics exhibit high toughness and impact resistance, light weight, low thermal conductivity and good water resistance, showing great application potential in thermal insulation, seismic-resistant high-rise buildings and durable construction materials.
