“…Figure 2 shows the Izod impact strength plotted against the PB rubber content for the different PVC/ABS blends prepared at milling temperatures of 165°C and 180°C. The impact strength of blends increased together with the PB rubber content as expected from previous studies [14,17,18]. At low PB rubber contents, all of the notched impact strength of brittle blends occurred in the range of 50-200 J/m, independent of the type of PVC resin used.…”

Abstract Acrylonitrile-butadiene-styrene (ABS) grafted copolymer prepared by emulsion polymerization was used to modify different molecular weight poly (vinyl chloride) (PVC) resins. The effects of the molecular weight of the PVC resins on dynamic mechanical analyses (DMA) of PVC/ABS blends and matrix plasticizing behavior on the impact mechanical properties and the morphology were investigated. The tan δ peaks of PVC/ABS blends occurred at the same temperature obtained by DMA, indicating that miscibility of PVC/ABS blends was independent of the molecular weight of PVC. The notched Izod impact test results indicated that the amount of polybutadiene (PB) rubber needed for the brittle-ductile transition (BDT) increases together with the molecular weight of PVC when milled at 165°C. Increasing the operation temperature and adding the plasticizer dioctyl phthalate (DOP) could change the matrix plasticizing extent and the BDT. At a milling temperature of 165°C, the BDT was reached only with 3.6 wt% PB when DOP was added, in contrast to the addition of 7.2 wt% PB in the absence of DOP. The morphology of different plasticized degree of PVC/ABS blends was studied by transmission electron microscopy (TEM) showing that the PVC-1/ABS blends milled at 165°C showed a larger unstained area than the other series of PVC blends.

“…The SAN copolymer was supplied by Jilin Petrochemical Corp (Jilin City, Jilin Province, China). The preparation of the ABS modifier is described in detail in our previous published article [14]. The average molecular weight (M w ) and the average molecular number (M n ) for the SAN copolymer were 148,000 and 49,400 g/mol, respectively.…”

Waveguide ring resonator is the sensing element of resonant integrated optical gyroscope (RIOG). This paper reports a polymer-based ring resonator with a low propagation loss of about 0.476 dB/cm for RIOG. The geometrical parameters of the waveguide and the coupler of the resonator were optimally designed. We also discussed the optical properties and gyroscope performance of the polymer resonator which shows a high quality factor of about 105. The polymer-based RIOG exhibits a limited sensitivity of less than 20 deg/h for the low and medium resolution navigation systems.

“…First, computer numerical control (CNC) machining was used to manufacture the PC module and spacer. PC was used because it is inexpensive, easily machinable, and has a relatively high tolerance to heat and impact [24]. Second, an etching process was used to fabricate the Yagi antenna and FR4 reflector.…”

A compact receiving (Rx) antenna integration for 3D direction-finding passive radar is proposed. The proposed antenna integration consists of two Yagi antennas and two waveguide slot antennas. The antennas are mounted on four sides of a parallelepiped polycarbonate module with the same type of antennas facing each other on the opposite sides of the module. The antenna is designed for a directionfinding radar system as an Rx terminal on an avionic vehicle with a separate Tx base station on the ground. The proposed antenna integration demonstrates a maximum return loss of 9.6 dB (voltage standing wave ratio 2:1) ranging from 9.7 to 10.2 GHz in the X band and has suitable radiation patterns for direction-finding system in both the xz and yz planes. In addition, the proposed antenna integration has the compact size and light gross weight of 37 mm × 46 mm × 50 mm and 97 g, respectively, making it suitable for application in an avionic system.
