This work investigates the quasi-static, low-cycle and fatigue behavior of hybrid glass/ultra-high modulus carbon (GC) low modulus/ /high (CC) fiber composites. These pseudo-ductile unidirectional interlayer hybrids are a new type composites whose potential is not yet fully understood, particularly under cyclic/fatigue loading. Different test methods (digital image correlation, video extensometer thermal camera) were used to record evolution strain, damage temperature during The results...
Hybrid fiber-reinforced polymer (FRP) composites, combining different types of fibers within a polymeric matrix, have piqued the research community's interest due to their enhanced mechanical properties and functional performance. These materials offer optimized fiber usage, tailored failure responses, potential for pseudoductile behavior. Furthermore, hybridization avoids catastrophic tensile despite composites being composed entirely brittle materials. Empirical evidence from previous...
This paper presents research concerning the numerical analysis of two new carbon composite materials subjected to high-velocity impact. These composites were produced using out-of-autoclave processes, making them more environmentally friendly. An experimental campaign was conducted on these in order determine effects a metal sphere during A model ABAQUS explicit is assembled shell finite element models, and non-linear dynamic applied. For constitutive relation material, fiber-reinforced...
The Vacuum-Assisted Resin Transfer Molding (VARTM) process has gained popularity as a reliable and cost-effective alternative to autoclave molding for high-performance composite production, which is especially interesting aeronautics, where weight reduction crucial. However, date, the environmental impact of components produced through VARTM remains relatively unknown. To address this gap, study applied Life Cycle Assessment (LCA) methodology estimate thermoset laminate heated VARTM. Aiming...
The performance of a progressive damage model in quantitative hybrid effect prediction comprehensive set different 16 unidirectional interlayer (layer-by-layer) composites was assessed. Composites, produced by the hand lay-up method, made out four commercially available dry fabric materials, namely high-modulus carbon, standard E-glass and basalt, were tested. Tensile tests on single fibres performed order to determine their Weibull strength distribution parameters, which used as inputs...
Composite materials are increasingly being used in aircraft components such as fuselage panels which subject to collision with debris during take-off/landing or flight. This article provides an analysis of the impact resistance capability graphene doped T700 (T700G) multilayer composite, when subjected steel projectile impacts. Test coupons 300x300 mm were impacted by spherical projectiles, energies ranging from 34 J 338 J, using a compressed air operated cannon. data, and absorbed energy...
