Cortex and xylem fibers extracted from castor oil plant residue using a standardized method were used to fabricate unidirectional long fiber and short random fiber composites. Various fiber volume fractions (10 %, 20 %, 30 %, 40 %) and fiber lengths (5 mm to 40 mm) of cortex fibers were tested according to ASTM standards and results showed that fibers of diameters 275 μm to 325 μm, have superior tensile strength (290 MPa to 346 MPa) compared to xylem fibers (90 MPa to 140 MPa). Composites of 40 % volume fraction cortex fibers aligned longitudinally exhibited the highest tensile (76.35 MPa), flexural (121.45 MPa), and impact strength (6.99 kJ/m2) significantly improved compared to the epoxy matrix. For short random cortex fiber composites, the optimal mechanical performance was achieved with 20 mm fibers and a 40 % volume fraction, resulting in the highest tensile strength (32.12 MPa), flexural strength (84.31 MPa), and impact energy (40 J/m). These results highlight the potential of castor oil cortex fibers to enhance the mechanical properties of epoxy composites for various engineering applications.","PeriodicalId":18366,"journal":{"name":"Materialwissenschaft und Werkstofftechnik","volume":"56 2","pages":"290-304"},"PeriodicalIF":1.2,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143388942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dry sliding wear studies revealed that the coefficient of friction increases with an increase in applied load and sliding velocity. The specific wear rate for all composites increased with an increase in applied force. Nine experimental runs were performed using Taguchi L9 orthogonal array. The optimum control factors were predicted according to the MINITAB16 software. Analysis of variance has been applied to predict the highly significant operating parameter.

L9 orthogonal array (OA) robust experimental design was selected for conducting the dry turning operations. The input variables included cutting velocity, depth of cut, and feed rate, while the output responses measured were surface roughness (Ra) and cutting force (Fc). The influence of these process variables was determined through analysis of variance (ANOVA). ANOVA results revealed that cutting speed, feed rate and depth of cut were impacting the average surface roughness by 36 %, 29 %, and 31 %, respectively and influencing the cutting force by 2 %, 16 %, and 72 %, respectively, during turning operation. Empirical models for predicting cutting force and surface roughness were developed using the Taguchi meta-heuristic algorithm. The optimization process resulted in a significant reduction in surface roughness, with Ra decreasing by 17 % and a notable decrease in cutting force, Fc, by 8 %. These numerical improvements indicate that the proposed optimization approach substantially enhances machining performance, validating its effectiveness.","PeriodicalId":18366,"journal":{"name":"Materialwissenschaft und Werkstofftechnik","volume":"56 2","pages":"281-289"},"PeriodicalIF":1.2,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143389460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the last years, the variety of different resins is highly enhanced towards polymers that meet high requirements – mechanical, optical and thermal properties as well as electroconductivity. To our knowledge, direct electroplating is not investigated so far. The aim of our work is the development of a composite material that is able to be processed by stereolithography and that provides the electroconductivity for direct electroplating. Direct electroplating highly improves the process of electroplating on polymers because of less process steps and the avoidance of toxic chemicals. With regard to material efficiency and saving resources, direct electroplating may be more environmental than the established industrial process of electroplating on polymers. A commercially available synthetic resin is our base material. Electroconductive filler are graphitic particles with different shapes and sizes. By varying the additives content, the effects on homogeneity and viscosity of the composite resin, its hardenability and the electrical resistance of the manufactured samples are investigated.","PeriodicalId":18366,"journal":{"name":"Materialwissenschaft und Werkstofftechnik","volume":"56 1","pages":"8-16"},"PeriodicalIF":1.2,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mawe.202300370","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143115249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These objects are produced by feed-stocking and fusing materials layer by layer. Compared to conventional manufacturing, additive manufacturing can make geometrical shapes that are very complex within a short time with less material wastage. Remarkable applications of manufacturing technology are found in automobile, aerospace, medicine, and natural/synthetic fibre-reinforced composites. Manufactured parts are fabricated using metals, ceramics, and mainly polymers or composites. Advancements in research have recently been implemented to optimize the process. This review focuses on the research progress on current methods applied to optimize 3D printed biopolymer medical implants and natural/synthetic fibre-reinforced composites. The objective of this article is to review new opportunities to produce multifunctional materials and suggest solutions to solve persisting challenges in additive manufacturing of medical implants using natural/synthetic fiber reinforced composites. The influence of process parameters on output performance measures, as well as the modelling and simulation techniques applied, are critically established in this paper. Current 3D printing processes and technologies, including the status and future of additive manufacturing, are also critically presented.

Alloy composites have been produced with varying concentrations of reinforcement by a two-step stir-casting method. X-ray diffraction (XRD) confirmed the presence of fly ash and red mud whereas microstructural analysis through optical microscopy showed a uniform distribution of the reinforcements within the alloy matrix. The composite formed with optimized weight fractions of red mud and fly ash exhibited higher ultimate tensile strength in comparison with base aluminium alloy. Furthermore, the dry sliding wear behaviour of the alloy and its composites have been investigated at low sliding speed against a hardened disk at three different loads (2 kg, 3 kg and 4 kg). The wear rate increases with increasing load in the alloy as well as in the composite. Sem images of worn surfaces of the hybrid composite exhibit fewer grooves when 5 wt.-% of both reinforcements are present. Essentially, the overall wear rate of the composite is found lower than the base alloy. Hybrid composites with 5 wt.-% of both reinforcements show maximum wear resistance.","PeriodicalId":18366,"journal":{"name":"Materialwissenschaft und Werkstofftechnik","volume":"56 1","pages":"122-131"},"PeriodicalIF":1.2,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mawe.202300378","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143115296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
