摘要
The present paper deals with the effect of loading different pineapple leaf fibre(PALF)length(short,mixed and long fibres)and their reinforcement for the fabrication of vinyl ester(VE)composites.Performance of PALF/VE composites was investigated through three-point bending flexural testing and viscoelastic(dynamic)mechanical properties through dynamic mechanical analysis(DMA).DMA results revealed that the long PALF/VE composites displayed better mechanical,damping factor and dynamic properties as compared to the short and mixed PALF/VE composites.The flexural strength and modulus of long PALF/VE composites were 113.5 MPa and 14.3 GPa,respectively.The storage(E′)and loss(E″)moduli increased to 2000 MPa and 225 MPa respectively for PALF/VE composites.Overall result analysis indicated that increasing the length of the reinforcement fibre results in satisfactory mechanical performance and dynamic properties of composites.
