poly lactic acid and poly butylene succinate blend fibers prepared by melt spinning technique
Energy Procedia, 2013Co-Authors: Lalita Jompang, Supaphorn Thumsorn, Prayoon Surin, Chiyaprek Apawet, Tirapong Chaichalermwong, Narin Kaabbuathong, Narongchai Ocharoen, Natee SrisawatAbstract:Poly(lactic acid) (PLA) and poly(butylene succinate) (PBS) were blended in a twin screw extruder at various contents of PBS from 0-50 wt%. PLA/PBS blends were melt spun using a single screw extruder equipped with multifilaments Spinnerette. The effect of PBS contents on morphology, thermal and mechanical properties of PLA/PBS blend fiber was investigated SEM micrographs indicated that the addition of PBS at 10 wt% was miscible with PLA while the other contents of PBS exhibited phase separation in the blends. The incorporation of PBS affected on the declination of crystallinity in the blends. It can be noted that the addition of PBS could enhance the elasticity of PLA/PBS blend fibers.

Study of 1-3 PZT fibre/epoxy composite force sensor
Springer, 2005Co-Authors: Sh Choy, Chan Hlw, Liu PckAbstract:Lead zirconate titanate (PZT) fibres were prepared by a powder-based extrusion method. Pre-sintered PZT powder mixed with poly(acrylic acid) was spun in a Spinnerette to produce fibres. The fibre of ∼ 400 μm diameter was used to fabricate 1-3 PZT fibre/epoxy composite discs with different volume fractions (ψ) of PZT. Since the ceramic fibres are rather brittle, their elastic properties cannot be measured directly. In order to determine the properties of the ceramic fibres, effective properties of the fibres/epoxy 1-3 composite were measured. By using a modified series and parallel model, the properties of 1-3 composites can be calculated. Then, the elastic coefficient s33,fibre E, relative permittivity ε 33,fibre T and piezoelectric strain coefficient d 33,fibre of the ceramic fibre could be found. Ring-shaped PZT fibre/epoxy materials composites with different ψ were fabricated to be used as the sensing material in force sensor applications. The ring-shape composite with ψ=0.5 was installed into a housing and the sensor was calibrated by different methods and its sensitivity was found to be 144 pC/N within the frequency range of 0.5-6.4 kHz which is much higher than that of a quartz force sensor with a similar structure.Department of Applied Physic

Study of 1-3 PZT fibre/epoxy composites with low volume fraction of ceramics
Taylor & Francis, 2004Co-Authors: Sh Choy, Chan Hlw, Liu PckAbstract:Lead zirconate titanate (PZT) fibres were prepared by the viscous suspension spinning process (VSSP). Pre-sintered PZT powder mixed with poly (acrylic acid) was spun in a Spinnerette to form fibres. The diameter of the fibre was 0.4 mm. The piezoelectric and ferroelectric properties of the single fibre were studied. The piezoelectric coefficient (d33) and the remnant polarization Pr for a single fibre were found to be 490 pC/N and 26 μC/cm2, respectively, which are comparable with that in the bulk sample. The fibres were used to fabricate 1-3 PZT fibre/epoxy composites with low volume fraction of PZT (<0.2). Different theoretical models were used to calculate the piezoelectric coefficient (d33) of the composites and compared with experimental results.Department of Applied Physic
