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

Angewandte Chemie International Edition, Accepted Article.Polyamides (PAs, nylons) are a ubiquitous class of high‐performance plastics used extensively in a wide range of applications. Their high resistance to many common solvents and tendency to hydrolyze in strong acids or bases creates a major hurdle to low‐emissions material recycling (i.e., resource separation and recovery).

Active Sterile Neutrino Conversions in a Supernova with Random Magnetic Fields [PDF]
arXiv, 1994 {Large enough random magnetic fields may affect in an important way neutrino conversion rates, even in the case where neutrinos have zero transition magnetic moments. We consider their effect in the case of active to sterile \neu conversions in a supernova and show that for KeV neutrino masses these limits may overcome those derived for the case of ...

Multi Jet Fusion PA12 Manufacturing Parameters for Watertightness, Strength and Tolerances [PDF]
Materials, 2018 The aim of this paper is to explore the watertightness behaviour for high pressure applications using Multi Jet Fusion technology and polyamide 12 as a material. We report an efficient solution for manufacturing functional prototypes and final parts for water pressure applications and provide manufacturing rules for engineers in the pressurized product
