Fast Cooling

The PVDF (poly(vinylidene fluoride)) is the recommended material for pressure barrier application when the temperature is above 90 C and below 130 C (API Specification 17J). Two grades of PVDFs used in flexible raisers were processed. The grades selected were those for extrusion, but they were compression molded instead. The processing conditions were the same for each grade, from slow to fast cooling rate. The results allowed the evaluation of their performance using a simpler processing technique and, also, to observe how the mechanical properties varied with the cooling rate applied.

Acid-functionalized carbon nanotube (fCNT)-poly (vinylidene fluoride) (PVDF) composite films with different CNT contents (0-0.5wt%) were prepared by melt-blending followed by compression molding. The electrical resistance (R) of the composite films under tensile loading was measured by a two-probe method using a custom made equipment connected to digital multimeter. The films (0.35 and 0.5wt% fCNT composites) showed exponential increases in R with displacement after attaining the elastic strain. Further, the change in resistance divided by resistance (ΔR/R) showed a linear increase with strain (ε). The slope of the linear region is found to be higher for 0.35wt% fCNT composite (5.4) as compared to 0.5wt% fCNT composite (3.4), indicating a better sensitivity in the former case. This may be due to less number of electrical conducting paths in case of 0.35fCNT composite. On account of the results obtained, the composites promise as potential candidates for strain sensing in health monitoring.
