TY - JOUR TI - Effect of filaments diameter on the mechanical properties of wrap hybrid CFRP AU - RUAN, FANGTAO AU - XIA, CHENGLONG AU - YANG, LI AU - XU, ZHENZHEN AU - TAO, FEIYAN T2 - Industria Textila AB - In this paper, the vine-like structure of carbon bundles was designed through polyester fibre wrapping for bettermechanical properties. The effect of wrapped hybrid structure and diameters of polyester fibre on the mechanicalproperties of carbon-polyester fibre/epoxy unidirectional composites was investigated experimentally. Five kinds ofspecimens with different polyester filament diameters were produced. The impact, tensile and unidirectionalcompressive properties of WHC (Wrap Hybrid Composite) were measured. Experimental results show that: it can bedeveloped with strength and toughness properties far superior to those of their constituents, the compressive fracturemorphology of specimens indicated that the fracture patterns of composites depend on wrapped hybrid structure,polyester fibres with higher tensile strengths provide better impact resistance, while thinner wrapping fibres enhance thecompression properties of the composite material more effectively. The diameter of the wrapping fibre should beoptimized as per the application of the composite material. The vine-like structure can provide a new design method forthe structural design of continue fibre reinforced composite materials.
