The reinforcements were polyacrylonitrile based high strength CFs. The properties of materials used were given in Table 1. Carbon fibre surface treatment Carbon fibres were oxidised by boiling in HNO3 under reflux for 5 h (T5120uC). Afterwards， the nitric acid oxidised fibres were washed with distilled water to neutral pH. Fibre surface composition The fibres were characterised by X-ray photoelectron spectroscopy (ESCA 300， Scienta， Sweden) to determine the level of functionalisation of the modified fibres. An initial survey scan was performed to determine the detectable elements， followed by high resolution scans. The entire X-ray photoelectron spectrum was energy referenced to the C1s peak of graphite (bending energy5284?5 eV). Composite preparation Before processing， ABS pellets and CFs were dried in a vacuum oven for 4 h at 80uC. Composites containing 0， 5， 10， 15， 20， 25 and 30 wt-% SCF were prepared by melt mixing in a co-rotating twin screw extruder (Thermoprism TSE 16 TC， L/D:24). The ABS pellets and CFs were fed from the main and side feeders respectively. The molten composite obtained from the die of the extruder was water cooled and pelletised. The extrusion conditions were arranged， as shown in Table 2. The viscosity of the melt containing CFs depends on the viscosity of the polymer matrix as well as the processing temperature. To avoid unfavourable shearing conditions， the melt temperature is kept as high as possible regarding thermal degradation. Before PA6 was blended to promote interfacial adhesion， vacuum drying of the ABS and PA6 pellets was carried out at 80uC for 4 and 12 h respectively. The 0， 10， 20 and 30 wt-% PA6 containing batches were fed through the main feeder to the twin screw extruder. The extrudate was water cooled and chopped into small pellets. The produced ABS/PA6 pellets were vacuum dried again at 80uC for 12 h. To prepare the SCF reinforced ABS/PA6 composites， the blend was introduced into the twin screw extruder from the main feeder， and SCFs were fed from the side feeder. The twin screw extruder was operated at the same processing conditions used during the blend preparation. The extrudate was again water cooled and chopped into small pellets. The extrusion grades of resin were used to make the extrudate form fully. The specimens for the mechanical characterisation experiments were moulded using a laboratory scale injection moulding machine (microinjector， model 1998; Daca Instruments) at a barrel temperature of 230uC and mould temperature of 80uC. The injection moulding machine used in this study was a laboratory type microinjector. The principle of the operation is that the preweighed (，2?5 g) raw material is loaded into the cylindrical barrel and allowed to melt at a preset barrel temperature for 1 min.Then the molten plastic is pushed through an injection tip by a piston. 展開

Wells-Brookfield Cone/Plate Rapid Determination Of Absolute Viscosity Introduction The Wells-Brookfield Cone/Plate Viscometer gives researchers a sophisticated instrument for routinely determining absolute viscosity of fluids in small sample volumes. Its cone and plate geometry provides the precision necessary for development of complete rheological data. Principle of Operation The Wells-Brookfield Cone/Plate Viscometer is a precise torque meter which is driven at discrete rotational speeds. The torque measuring system， which consists of a calibrated beryllium-copper spring connecting the drive mechanism to a rotating cone， senses the resistance to rotation caused by the presence of sample fluid between the cone and a stationary flat plate. The resistance to the rotation of the cone produces a torque that is proportional to the shear stress in the fluid. The amount of torque is indicated either on a dial or digital display， depending on model. This reading is easily converted to absolute centipoise units (mPa.s) from pre-calculated range charts. Alternatively， viscosity can be calculated from the known geometric constants of the cone， the rate of rotation， and the stress related torque. See Range Tables The correct relative position of cone and plate is obtained by following a simple mechanical procedure without the need for external gauges or supplementary instrumentation. The stationary plate forms the bottom of a sample cup which can be removed， filled with .5 ml to 2.0 ml of sample fluid (depending on cone in use)， and remounted without disturbing the calibration. The sample cup is jacketed and has tube fittings for connection to a constant temperature circulating bath. The system is accurate to within ?.0% of the working range. Reproducibility is to within ?.2%. Working temperature range is from 0oC to 100oC. 展開

高分請高手幫忙翻譯英文文獻資料（4）: Whenliquidisheateditevaporates.Theevaporationprocessisdependentonpressure，temperatureandcompositionoftheliquidandgas.Gascanalsocondense.Inadditionthereisaconvectiveheattr... When liquid is heated it evaporates. The evaporation process is dependent on pressure， temperature and composition of the liquid and gas. Gas can also condense. In addition there is a convective heat transfer between the liquid and gas zone that must be considered. The surfaces in the gas zone also radiates from the shell to the liquid. During the blowdown process mass is usually evacuated from the gas zone， but also liquid might be released. The rate of release is dependent on density and pressure as well as the release area. As pressure and temperature change， the properties of all materials change. This has to be considered in a prediction of a blowdown process. The main purpose of a blowdown process is as earlier stated to maintain integrity of the equipment. The strength properties of the shell are the key factor on that matter. The strength is dependent on the inside pressure as well as the support forces. If the exposing forces produce stress that exceeds the ultimate tensile stress (UTS) in some regions， the integrity of the equipment is no longer maintained. In the design phase of a process plant， these aspects are crucial and must be included as a dimensional factor. For that reason prediction of the blowdown process is essential. Lately some new standards has been introduced to the industry on this matter [3] and [4]. VessFire [1] and [2] is a multi physics system designed for calculation of this kind of problems. It has been applied for some time in the oil and process industry on many projects. The system satisfies the requirements for predictions outlined in [3] and [4]. It includes all aspects described above including integrity of the shell. As part of the verification process some experiments where performed. Some of the experiments are presented here. EXPERIMENTAL STUDY The purpose of the experiments was to investigate the evaporation process and the heat transfer to the liquid and vapour. In a complex system it is important to reduce unknown parameters as far as possible. Exposure from a flame is difficult to control. Flux measurements are point values and not necessarily representative for the average exposure. In order to control the heat exposure it was decided to apply an electric heating system. The system and the verification of the system is described in [5]， [6] and [8]. The furnace was built inside a supporting tube. Figure 2 shows a general arrangement of the experimental outfit. A 0.05 mm stainless steel foil formed as a tube， 300 mm in diameter， generated the heat. The power supply was based on a 3-phase alternating current system giving 48 Volt output as maximum. The top exposure had a limit of 300 kW. The foil had a surface of about 1 m2， giving a heat flux up to 300 kW/m2. The power input could be continuously regulated from zero to maximum load. Each experiment was started from zero and brought up to the required load within a few seconds. After that the surface temperature of the heating foil was kept constant during the exposure period. Experiments with both dry objects as well as water filled object were performed. In this paper only water filled experiments are presented Figure 2 General arrangements drawing of the experimental furnace including the specimen and its support Figure 3 Illustration of the heating unit. The black part is copper conductors for the foil. The grey part is the heating foil exposing the specimen. The foil is equipped with thermo-elements all marked H， except H5 which is the temperature in a copper ring and H6 which is the temperature between the insulation and the supporting tube. 展開

The SEM is calculated by this equation:SEM=SD/N. With large samples， the SEM is always small. By itself， the SEM is difficult to interpret. It is easier to interpret the 95% confidence interval， which is calculated from the SEM. 展開
