The design principle of rasorber radomes is qualitatively analyzed based on the equivalent circuit theory. The prototypes are designed with a multi-layered configuration and constructed using quartz fiber dense skins, polymethacrylimide (PMI) foam cores, PIN diodes, carbon-based films, and the functional layers with copper patterns. The dynamic control of transmission is implemented by applying varying bias voltages to PIN diode elements. To obtain mechanical protection, the delicate PIN diodes are cured together with the preforms and embedded in the matrix. To stabilize the absorption out of the transmission band, the carbon-based films are overprinted at the reserved gaps of the copper patterns. The measured results demonstrate that as the bias voltage varies, within 2–4 GHz, the transmission of the rasorber radome dynamically varies from 0.8 (at 0 V) to 0.05 (at 50 V), while the absorption dynamically varies from 0.05 (at 0 V) to 0.7 (at 40 V). Within 8–22 GHz, the absorption is consistently more than 0.9, which is independent of the variation of bias voltages. The measured results align well with the simulated results. The rasorber radome can function as a radome to ensure normal operations of an enclosed antenna and also function as a radar absorber with variable absorption responses to avoid radar detection and tracking. Therefore, our proposal possesses considerable engineering application potential in stealth radome technology.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"300 ","pages":"Article 112467"},"PeriodicalIF":12.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143768283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, carbon fiber's chemical inertness results in weak interactions with the polymer matrix, which hinders the overall performance of the composites. Improving the interfacial properties has been a longstanding challenge in CFRPs development. Introducing nanomaterials along with chemical agents at the interface can enhance both physical and chemical interactions, facilitating better load transfer and more uniform stress distribution. Despite this, surface modification remains a complex process, and the lack of anchor bonds limits the effectiveness of chemical interactions. In this work, inspired by the crack-resistance mechanism of byssal cuticle through metal coordination bonds, we introduce a metal-phenolic network comprising ferric iron (Fe³⁺) and tannic acid (TA) onto the carbon fiber surface using a simple one-pot deposition method. This approach significantly enhances the interfacial properties of the composite. The Fe³⁺-TA complex forms nano-sized aggregates on the fiber surface, with their morphology controllable by adjusting the precursor concentration and pH. The multiple reactive groups on TA allow for the incorporation of a silane coupling agent, effectively creating a chemical bridge between the carbon fiber and the matrix, further improving interfacial properties through synergistic chemical and physical interactions. This metal-phenolic network not only simultaneously strengthens and toughens the interface by promoting mechanical interlocking but also provides multiple chemical anchor sites to bridge the two components, offering new insights into strategies for interfacial strengthening and regulation.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"300 ","pages":"Article 112466"},"PeriodicalIF":12.7,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143746748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study proposes an unsteady rolling method for fabricating the high-quality Ti₂AlNb/7075Al LMCs. The interfacial bonding rate reaches 88 %. These LMCs with a density of 3 g/cm³ demonstrate excellent mechanical properties, achieving a tensile strength exceeding 650 MPa and an elongation greater than 16 %. Precise strength matching between Ti₂AlNb and 7075Al is achieved during unsteady heat treatment at 650–700 °C for 1–3 min. Within this range, 7075Al shows no signs of over-burning and its tensile strength decreases by only 25 %. Meanwhile, Ti₂AlNb does not experience hardening caused by O-phase precipitation and demonstrates excellent plasticity. This excellent mechanical property matching results in coordinated deformation of the two metals during the rolling process. A few Ti₂AlNb grains undergo kinking to accommodate the deformation. The Ti₂AlNb layer near the interface forms shallow rectangular tear gaps, which are filled by 7075Al, creating a strong mechanical interlocking. Meanwhile, the rapid rolling process prevents the formation of brittle products at the interface. Atomic scale bonding is observed at the interface of the Ti₂AlNb/7075Al LMCs.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"300 ","pages":"Article 112458"},"PeriodicalIF":12.7,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143786212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over the past decade, Material Extrusion (MEX) has gained popularity as a method for additive manufacturing of metal parts, particularly for producing green parts, due to its flexibility and cost-effectiveness. Specifically designed feedstocks for MEX process have to be provided to achieve high quality properties of metal parts. However, the development of composite filaments with required high-volume metal and MEX-compatible binder matrices remained limited. In this study, a metal/biopolymer composite filament is developed based on CuSn10 metal powder at 65 vol% combined with two novel binder matrices: the first consisted of the binders polylactic acid (PLA) and acetyl tributyl citrate (ATBC), while the second combined PLA, butenediol vinyl alcohol copolymer (BVOH), and ATBC as plasticizer. The binder components are biocompatible and environmentally sustainable. The green parts were successfully printed through MEX and then processed via thermal debinding and sintering in an open atmosphere. Both the debinding and sintering processes were successful and environmentally friendly. The filaments and the resulting metal parts were thoroughly characterized. The results revealed that the feedstock was extremely brittle without the plasticizer. Increasing the plasticizer content improved flowability but led to poorer surface roughness of the filament. Incorporating BVOH reduced the surface roughness and decrease viscosity. The optimal binder matrices were identified as PLA with 10 vol% ATBC and PLA/BVOH with 5 vol% ATBC. CuSn10 parts produced from these new filaments show significant improvements in the mechanical properties, relative density and porosity.

To address this issue, a low-cost and high-efficiency additive strategy was developed.
