Butadiene Styrene

Dynamic Mechanical Analysis (DMA) tests are carried out to investigate the viscoelastic deformation of Polycabonate (PC), Acrylonitrile-butadiene-styrene (ABS) and PC/ABS alloys with ratio of PC to ABS being 60/40, 50/50, 40/60, respectively. Storage and loss moduli of PC, ABS and PC/ABS alloys are measured from 0.01Hz to 200Hz at 95oC with DMA tests. The relaxation moduli of PC, ABS and PC/ABS alloys are tested from static tests and compared with those calculated from storage and loss moduli. Effect of ABS fraction on storage and loss moduli and relaxation modulus of PC/ABS alloys is also discussed.

Polyester Matrix

Polyester based composites were fabricated and characterized for their tensile, morphological and dynamic mechanical properties such as storage and loss moduli as a function of temperature. The morphological attributes were characterized by scanning electron microscopy (SEM) and COSLAB microscope. The morphological investigations have revealed a uniformly distributed polyester matrix of the composites. Dynamic mechanical analysis (DMA) revealed an enhancement in the energy dissipation ability of the composite 4GF and an average storage modulus of the composite 3GF/1FN relative to the soft polyester phase. The tensile modulus and tensile strength increased up to 0.5 %, accompanied by while the strain at break remained largely unaffected. Fractured surface morphology indicates that the failure mode of the composites undergoes a switch-over from matrix-controlled shear deformation to the filler-controlled loading of the composites for specific applications. Hence, the utilization of discarded fishnet incorporated composites mitigates the problem of waste disposal.
