中文摘要 | 聚丁烯對苯二甲酸酯的耐衝擊強度可經由加入乙烯-丙烯橡膠改良。但其模數,強度及熱變形溫度亦會相對降低。利用鈷六十珈瑪射線照射可以防止脫層現象並降低其耐衝擊強度。加入玻璃纖維於PBT/EPR聚摻合物中可改良上述之缺點而略增加耐衝擊強度。此外,耐衝擊的斷裂面利用掃描式電子顯微鏡觀察以了解其形態學及破壞現象。 |
英文摘要 | The impact resistance of polybutylene terephthalate (PBT) had been improved through blending with ethylene-propylene rubber (EPR). This improvement resulted in a reduction in modulus, strength and heat distortion temperature. Co□ γ-ray radiation treatment would prevent laminar peeling pheonmena, but reduce impact strength. The addition of glass fiber in PBT/EPR polyblend imparted improvement in modulus, strength and heat distortion temperature, however the impact strength was only marginally better than glass fiber reinforced PBT. The morphology and fracture machanism of PBT/EPR polyblend and PBT/EPR/Glass-fiber composite were invetigated using scanning electron microscopy to examine impact fracture surface and solvent-etched cut through surface. |
