Journal of Applied Polymer Science, EarlyView.Cooling holes provide a simple passive cooling strategy for polymer spur gears, reducing maximum operating temperature by up to 9.39% while introducing a measurable gear mesh stiffness penalty. A validated response‐surface model reveals how hole size and location govern this thermal–mechanical trade‐off, enabling design optimization for thermally and ...

The Reactive Blend of PPS/PA12 [PDF]
, 2014 PPS/PA12的聚摻合,PA12分散相粒子的粒徑大小,不會因反應性單體(GMA、MAH)的加入而有明顯的變化,但是,其微觀相形態與熱行為卻有極大的差異。GMA與MAH具有雙官能基,藉此與聚摻合物中不同相的高分子以原位化學反應在界面形成PPS-PA12段式共聚合物充作相容劑,使PPS的結晶態有部分轉移成無定形態,有利於PPS的增韌效果。GMA會使PA12產生交聯反應,在PPS連續相中形成PA12第二分散相。This report presents a study of the relationship ...

Improved Mechanical Properties of Compatibilized Polypropylene/Polyamide-12 Blends
International Journal of Polymer Science, 2015 Compatibilized blends of polypropylene (PP) and polyamide-12 (PA12) as a second component were obtained by direct injection molding having first added 20% maleic anhydride-modified copolymer (PP-g-MA) to the PP, which produced partially grafted PP (gPP).

CF/PA12 composite femoral stems: Manufacturing and properties
Composites Part A: Applied Science and Manufacturing, 2008 Abstract The fabrication process for a novel carbon fiber-reinforced polymer (polyamide 12) composite femoral stem using inflatable bladder molding was studied. Effect of processing temperature, holding time and applied internal pressure on the consolidation quality of the composite was investigated. Consolidation quality was evaluated by density and
