Bioresorbable composites prepared for mechanical performance are promising candidates as cardiovascular stent material.
Compression-and-shear deformation of amorphous polycarbonate
High-strain-rate compression and shear experiments in amorphous polycarbonate reveal strong sensitivity of yield stress to strain rate as well as coupling of dynamic shear behavior to dilatation.
Toward more durable carbon fiber composites
Surprisingly, hygrothermal exposure causes higher levels of degradation to fluorinated epoxy-based microcomposites, despite lower moisture absorption, than their nonfluorinated epoxy counterparts.
Characterization of metallocene polyethylenes for sealing layer applications
Molecular weight, molecular weight distribution, chain branching, and melting behavior of metallocene polyethylenes play a crucial role in the sealability and hot tack properties of their films.
