主要在研究聚四甲基一戊烯之物性與機械性質之研究,不同熱處理過程其機械性質的變化

Poly (4-methyl-1-penetene) (TPX) specimens are made with three different cooling rates. The x-ray shows the patterns of furnace cooled, air-cooled, and 0 ℃ water-quenched samples.
For the DSC test, the furnace-cooled, air-cooled, and 0 ℃ water-quenched samples are tested by dose of gamma-ray 0 kGy to 500 kGy. It shows the melting temperature and enthalpy decreased with increasing the gamma-ray dose.
For the tensile test, the furnace-cooled, air-cooled, and 0 ℃ water-quenched specimens were performed from 25℃ to 90 ℃ in air with cross-head speed 2.4 mm/min and 0.24 mm/min. The stress intensity factor experiments were performed from 25 ℃ to 90℃ in air with cross-speed 2.4mm/min and 0.24mm/min. The Kc values decreased proportionally with increasing temperature. At the same temperature, the Kc values of 0 ℃ water-quenched specimens is higher than air-cooled specimens, and furnace-cooled one is the smallest. The Kc values of cross-head speed 2.4mm/min are all higher than cross-head speed 0.24mm/min.
The gamma-ray effect on stress intensity factor experiments of the furnace-cooled, air-cooled, and 0 ℃ water-quenched specimens are tested by dose of gamma-ray 0 kGy to 500 kGy with cross-head speed 2.4mm/min and 0.24mm/min. The Kc values decreased proportionally with increasing dosage. The Kc values of 0 ℃ water-quenched specimens are higher than air-cooled specimens, and the furnace-cooled ones are the lowest.
