Damage healing ability of a shape-memory-polymer-based particulate composite with small thermoplastic contents
Open accessAbstract
The purpose of this study is to investigate the potential of a shape-memory-polymer (SMP)-based particulate composite to heal structural-length scale damage with small thermoplastic additive contents through a close-then-heal (CTH) self-healing scheme that was introduced in a previous study (Li and Uppu 2010 Comput. Sci. Technol. 70 1419–27). The idea is to achieve reasonable healing efficiencies with minimal sacrifice in structural load capacity. By first closing cracks, the gap between two crack surfaces is narrowed and a lesser amount of thermoplastic particles is required to achieve healing. The particulate composite was fabricated by dispersing copolyester thermoplastic particles in a shape memory polymer matrix. It is found that, for small thermoplastic contents of less than 10%, the CTH scheme followed in this study heals structural-length scale damage in the SMP particulate composite to a meaningful extent and with less sacrifice of structural capacity.

Small thermoplastic contents as low as 3% can heal structural-length scale cracks with high healing efficiency and with low sacrifice of material load carrying capability.
“Small thermoplastic contents as low as 3% can heal structural-length scale cracks with high healing efficiency and with low sacrifice of material load carrying capability [183].”
From A review of stimuli-responsive shape memory polymer composites (2013) · cites this paper as [183]
The Conclusions report that 3% thermoplastic content healed structural-length-scale damage with less sacrifice of load capacity. Section 3.3 reports a 51.2% damage-healing ability at 3%, but explicitly distinguishes that measure from healing efficiency, which it says could not be determined. Thus the claim’s characterization as high healing efficiency is not supported. (LLM, conf=0.87)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
