The objective of the work is to examine the effect of infill density to create mass-efficient structural parts through AM technology without compromising mechanical and thermal integrity for space applications. The proposed work conducted the original exploration of the mechanical and thermal behavior of PA12-CF composite printed through fused deposition modeling (FDM) at different infill densities (60%, 80%, and 100%). A comprehensive correlation between infill density, weight efficiency, and thermo-mechanical performance is developed, using Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) in multi-criteria optimization. The mechanical tests involved tensile, compression, flexural strength, and fracture toughness, and the thermal tests were performed by hot disc transient plane source (TPS) and differential scanning calorimetry (DSC). The findings show that the highest specific compressive strength, 51.53 kN·m/kg, flexural strength, 76.67 kN·m/kg, and fracture toughness of 80.79 MPa can be achieved with 100% infill density. Nevertheless, the greatest specific tensile strength of 56.09 kN·m/kg is produced by 80% infill, which is 2.32% higher than the fully dense part. Based on the TPS outcomes, higher infill density leads to higher thermal conductivity and heat capacity, reaching 0.3873 W/m·K and 1.7620 MJ/m³·<span>(:text{K})</span>, respectively. The maximum temperature obtained from DSC analysis is 170 ˚C. The TOPSIS outputs determine that the 100% infill is the best possible solution for balancing the thermo-mechanical properties.</p></div>","PeriodicalId":737,"journal":{"name":"Polymer Bulletin","volume":"83 12","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149132320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluates the influence of CQDs surface chemistry, photoluminescence quantum yield (QY), and incorporation route on curing behavior and final coating properties. Two CQDs with distinct QY values (≈23% and ≈62%) but similar surface functional groups were incorporated into WPUA dispersions via aqueous-phase addition and acetone pre-dispersion. Photo-DSC analysis revealed that CQDs broadened curing profiles, increased peak time from 4.2 s to 13.7–44.5 s, and reduced C=C conversion from 92.8% to 50.8–77.9%. A semi-quantitative analysis indicated that curing retardation arises from combined competitive UV absorption and route-dependent mobility restrictions induced by CQDs–WPUA interactions. Despite reduced conversion and gel content (97.8% to 83–93%), CQDs improved coating performance, increasing tensile strength from 4.3 MPa to 6.1–6.6 MPa (≈40–53%), and thermal stability (T<sub>10%</sub>) from 298.2 °C to 309.1 °C. The incorporation route affected curing and properties in a CQDs-dependent manner, while QY differences produced only minor kinetic effects, indicating that surface chemistry and matrix interactions govern the response more strongly than photoluminescence. Under air, selected formulations suggested an apparent attenuation of oxygen inhibition, consistent with auxiliary CQDs photoactivity. Hansen solubility parameter analysis further revealed a contraction of the solubility sphere, indicating a more constrained network with improved solvent resistance.

These cooling techniques were used for immobilizing a mechanically deformed shape during the programming stage of a classical hot thermomechanical cycle. The five polymer properties were selected as they are considered key determinants of the behavior of the material as a shape memory material. Additionally, the study investigated the effect of these cooling techniques on the shape memory cycle time and, consequently, on the functional efficiency of the classical hot cycle. The smart polymer material under study, an elastomer/small molecule blend shape memory polymer (SMP), was prepared by impregnating commercial rubber band (RB) for 2 h with stearic acid (SA) at a weight fraction of 31%. The cooling techniques used in this study consisted of cooling with ice water at 10 °C followed by cooling at room temperature (23 °C). The comparative results demonstrated that all shape memory properties ((γ<sub>rec</sub>, SM-index, <i>R</i><sub><i>r</i></sub>, <i>R</i><sub><i>f</i></sub>) increased when artificial (abnormal) cooling was applied. Furthermore, the strain which was intended to be frozen at 80%, was spontaneously released by only 9.6% after 10 min of artificial cooling. On the other hand, a much higher release of 57.7% occurred during the same period with natural cooling conditions. As a result, the freezing duration had to be extended from 10 min to bring the shape memory fill factor (<i>f</i><sub><i>sm</i></sub>) of both techniques closer to the ideal shape memory behavior (idea-SM-behaver). The increase in freezing duration significantly affected the overall cycle duration. The total shape memory cycle time based on natural cooling increased to 56 min, which is considerably longer than the 36-min cycle time achieved using artificial cooling. These findings highlight the superior functional efficiency of artificial cooling in classical hot thermomechanical cycle of SMPs.</p></div>","PeriodicalId":737,"journal":{"name":"Polymer Bulletin","volume":"83 12","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149132051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A mechanical characterisation was performed in accordance with ASTM standards to evaluate tensile strength, flexural strength, interlaminar shear strength (ILSS), hardness, density, and dynamic mechanical properties. Laminates reinforced exclusively with basalt fiber showed a decline in flexural strength, whereas those reinforced solely with UHMWPE fiber displayed a reduction in tensile strength. This reduction is attributed to the fabrication challenges encountered with higher fiber contents. To overcome these limitations, hybrid laminates with varying proportions of UHMWPE fiber (5–15 wt%) were developed. Among these, laminate LD, comprising 45 wt% basalt, 10 wt% UHMWPE, and 45 wt% epoxy, exhibited significant enhancements in both tensile and flexural properties. Further enhancement of interlaminar shear strength (ILSS) was achieved by incorporating natural garnet filler at 2–5 wt% into low-density (LD) laminates. The optimised laminate, designated LK2, comprising 45 wt% basalt, 10 wt% ultra-high molecular weight polyethylene (UHMWPE), 3 wt% garnet, and 42 wt% epoxy, exhibited a superior tensile strength of 406.4 MPa, a flexural strength of 603.25 MPa, an ILSS of 17.01 MPa, and enhanced damping properties, along with improved microstructure. The findings indicate that LK2 hybrid laminates offer a balanced combination of strength, stiffness, and damping capabilities over a temperature range of 25–140 °C.
