Functional Behavior

Shape Memory Polymer Composites (SMPCs) are smart materials showing the structural properties of long-fiber polymer-matrix together with the functional behavior of shape memory polymers. In this study, SM carbon fiber reinforced (CFR) composites have been produced by using a SM interlayer between two CFR prepregs. Their SM properties have been evaluated in comparison with traditional structural CFR composites without the SM interlayer by using an especially designed test. Active and frozen forces are measured during a thermo-mechanical cycle in the three-point bending configuration. Experimental results show that SMPCs are able to fix a temporary deformed shape by freezing high stresses.

Shape memory polymers (SMPs) have drawn wide attention of many researchers for its potential applications to shipping industry, aerospace, bionics engineering and mechanical engineering. Shape memory polymers composites (SMPCs) have ability to improve the properties and obtain attain new functions of shape memory polymers. In this paper, trans-1, 4-polyisoprene reinforced by carbon fiber is developed to improve the mechanical weakness of trans-1, 4-polyisoprene bulk. Composites with carbon fiber weight fraction of 5%, 10%, and 15% are fabricated by casting samples with an average length of 2 mm. The mechanical property of the trans-1, 4-polyisoprene reinforced by short carbon fiber is evaluated and the effects of short carbon fiber on shape memory behavior are investigated. The results indicate that there is an optimum fiber weight fraction between 5 and 15 wt% where exists an extremely low recovery ratio, re-crystallizing temperatures (Tc) and an extremely high tensile stress.
