Abstract This study examines the influence of damage on stiffness characteristics synthetic fiber (Glass)‐reinforced metal laminated composite panels through static deflection analysis. The fiber‐metal laminate (FML) structural panel deflections are obtained computationally via a mathematical model using third‐order kinematics in framework equivalent single‐layer theory. values numerically with help finite element steps. solution consistencies verified by convergence test and extended to perform validation. Additionally, numerical results compared in‐house experimental data FML bending considering properties damage. maximum deviation intact response was −4.27%, while for crack showed −0.57%. Again, is engaged obtaining varying different geometry‐dependent design parameters, including data. spherical geometry pre‐damaged structure demonstrates better deformation resistance under external loading. thickness ratio ( L/h ) angle layup scheme show higher response. Highlights A higher‐order FE delved compute damaged FML. validity values. inference parameters computed numerically. understandings significant discussed detail.

Abstract In this study, carbon fiber (CF) was recovered from reinforced polymer (CFRP) composite waste using microwave‐assisted chemical recycling technique, utilizing a combination of acetic acid and hydrogen peroxide in equal proportions. The mechanical properties the (RCF) were successfully improved by growing nanotubes (CNTs) on its surface microwave irradiation (720 W). Ferrocene used as catalyst for CNTs. scanning electron microscopy (SEM) analysis suggested hair‐like dense growth RCF surface. Raman spectral indicated existence D + D', G' peaks decline I /I G values 0.9 CNT‐grown (CNT_RCF) comparison to RCF, confirming CNT growth. subsequently develop composites. CNTs facilitated wettability acted an anchorage point at RCF/epoxy interface, resulting properties.
