Shape-Memory Polymer Composites
The development of shape-memory polymer composites (SMPCs) enables high recovery stress levels as well as novel functions such as electrical conductivity, magnetism, and biofunctionality. In this review chapter the substantial enhancement in mechanical properties of shape-memory polymers (SMPs) by incorporating small amounts of stiff fillers will be highlighted exemplarily for clay and polyhedr...
متن کاملA Shape Memory Polymer with Improved Shape Recovery
Thermally actuated shape memory polymers (SMPs) interest, both academically and industrially, due to their ability to memorize a permanent shape that is set during processing and a temporary shape that is later programmed by manipulation above a critical temperature, either Tg or Tm. However, the thermal triggering process for SMPs is usually retarded compared to that of shape memory alloys, be...
متن کاملMechanical energy dissipation using carbon fiber polymer–matrix structural composites with filler incorporation
Continuous carbon fiber composites with enhanced mechanical energy dissipation (vibration damping) under flexure are provided by incorporation of fillers between the laminae. Exfoliated graphite (EG) as a sole filler is more effective than carbon nanotube (SWCNT/ MWCNT), halloysite nanotube (HNT), or nanoclay as sole fillers in enhancing the loss tangent, if the curing pressure is 2.0 (not 0.5)...
متن کاملIonically Bonded Filler-Elastomer Composites*
Tertiary amine-modified corn starches were converted to their basic or hydroxide form and combined with carboxylated butadiene-acrylonitrile copolymer and butadiene-styrene-sulfonic acid polymer to produce ionically bonded filler-elastomer composites. An increasing percentage of the elastomer fraction in the starch-elastomer composite is insolubilized as the starch-to-elastomer ratio increases....
متن کاملModeling and Simulation of Magnetic Shape--Memory Polymer Composites
Composites of small magnetic-shape-memory (MSM) particles embedded in a polymer matrix have been proposed as an energy damping mechanism and as actuators. Compared to a single crystal bulk material, the production is simpler and more flexible, as both type of the polymer and geometry of the microstructure can be tuned. Compared to polycrystals, in composites the soft polymer matrix permits the ...
