Research at the Materials Research Laboratory, Pennsylvania State University has demonstrated the potential for improving hydrophone performance using piezoelectric ceramic/polymer composites. As part of an ONR-funded initiative to develop cost-effective manufacturing technology for these composites, Materials Systems is pursuing an injection molding ceramic fabrication approach. This paper bri...

The formation of nanoparticle-polymer composites that can be processed by injection molding from superparamagnetic magnetite (Fe3O4) nanoparticles (MNPs) and the polymerizable molecule styryl acetylacetonate (stacac) is described. The best composites were created by first synthesizing MNPs in the presence of a surfactant followed by replacement with an excess of stacac monomer in a surfactant e...

the variations in plastic injection molding process may lead to the inconsistency of molded parts' dimensions. furthermore, due to the speed of production as well as post-shrinkage of molded parts make the control of process difficult and give inaccurate molded parts. the objective of this research is to predict the dimensions of injection molded parts on the basis of cavity pressure durin...
