Abstract Integrating thermoset and thermoplastic materials in a single structure is fascinating approach, especially when looking for optimized performance characteristics. These advanced hybrid structures can achieve levels of efficiency, strength, resilience that are simply not attainable using material type. Subsequently, this work aims to examine the deformation behavior crashworthiness performances square glass fiber‐reinforced epoxy (GFRE) composite tubes filled with 3D‐printed polylactic acid (PLA). To this, three key 3D printing design parameters, is, infill pattern structure, density, layer height, were varied, each at four levels. The subjected quasi‐static lateral compression. For tested tubes, crashing load energy absorption responses recorded against displacement, failure modes analyzed. most effective parameter combination was identified complex proportional assessment (COPRAS) approach compared empty GFRE tubes. Additionally, cost ratio intended evaluate economic feasibility designed analysis concluded GFRE‐H30/0.20 configuration offers best efficiency. Highlights produced by means lay‐up wet‐wrapping hand 3D‐printing methods. developed compression loads. versus displacement plots accessible. Moreover, histories found. In addition, COPRAS method used find optimum configuration.

Abstract This work investigates the effect of printing parameters on crashworthiness performance square tubes made with polyethylene terephthalate glycol reinforced carbon fiber (PETG‐CF). was accomplished by analyzing three parameters, infill pattern structure, density, and layer height, each which changed across four levels. The specimens' structural then assessed using quasi‐static axial compression testing. In addition to carefully documenting failure histories, data crash load, absorbed energy, displacement responses were methodically recorded during Several critical measures, including initial peak load (), total energy (U), mean specific (SEA), force efficiency (CFE), used evaluate crashworthiness. A complex proportional assessment (COPRAS) method, employed determine optimal configuration. results indicate that honeycomb structure achieves highest values for , U, SEA, measurements 5.57 kN, 250.54 J, 4.64 15.27 J/g, respectively. Meanwhile, Schwarz P attains maximum CFE, a value 1.585. COPRAS further indicated HC‐30‐0.20 configuration exhibited best performance. Highlights designed configurations created FDM. exposed loads. crashing absorption curves against computed. Besides, histories detected. Furthermore, method is catch structure.

Abstract Mechanical properties of 3D printed continuous fiber reinforced polymer composites (CFRPCs) are generally lower than expected due to unavoidable voids and weak interfacial adhesion. However, previous research work has rarely been reported on introducing carbon nanofillers such as nanotubes (CNTs) graphene oxide (GO) reduce internal void defects improve adhesion CFRPCs. In this work, an innovative means CNTs GO is proposed for enhancing the mechanical hybrid Polyethylene terephthalate glycol (PETG) employed a matrix its excellent processability printing process. Continuous basalt (CBF) selected microscale filler high properties, low cost availability additive manufacturing. It shown that into PETG leads notably reduced porosity greatly improved between CBF PETG. As result, CFRPCs significantly enhanced by matrix. Finally, mechanisms analyzed The multiscale enhancement method characteristics easy implementation. This approach contributes novel idea preparing high‐performance reducing simply nanofillers. can expand material systems provide new development industrial applications.
