Effect of the Stacking Sequence on the Impact Response of Carbon-Glass/Epoxy Hybrid Composites

Abstract

This paper investigates low-velocity impact response of Quasi Isotropic (QI) hybrid carbon/glass fiber reinforced polymer composites with alternate stacking sequences. Cross-ply woven carbon and glass fibers were used as reinforcing materials to fabricate sandwiched and interlayer hybrid composites. For comparison, the laminates containing only-carbon and only-glass fibers were also studied. Drop weight test was used to impact the samples. The images captured by a normal camera demonstrated that localized damages (delamination) existed within plies. The hybrid laminates had smaller load drops, smaller maximum deflection, and higher maximum load compared to the single fiber laminates. In addition, carbon outside interlayer hybrid laminate showed the highest maximum load and energy absorption, showing the significant dependence of the impact performance on hybridization and stacking sequence. It was concluded that a hybrid composite would help improve impact performance of laminated composites compared to non-hybrid composites if they are properly designed.

Using digital image correlation to evaluate the bond between carbon fibre-reinforced polymers and timber

“…The DIC measurements were able to follow the nonlinear slip distributions at a low slip magnitude as theoretically described in the literature 9,10,45 and obtained from the use of equation (3). After the debonding load has been reached, the slip distributions of the anchored CFRP-to-timber joints tended to a linear configuration that, as expected, is confirmed by the replacement of the displacements made and missed by the DIC technique.…”

“…The use of CFRP composites also allows us to increase the strength and stiffness of all elements of the timber construction. In addition, their good thermal and acoustic insulation and their non-corrosion properties, 2,3 makes the use of FRP composites on timber constructions a very good alternative to other conventional materials such as metals. 2 The externally bonded or the near surface mounted (NSM) are just some examples of techniques that have been used to repair ancient timber buildings.…”

Mechanical and Physical Characteristics of Bubble Alumina Reinforced Aluminum Syntactic Foams Made Through Recyclable Pressure Infiltration Technique

“…The energy absorption capacity is highly critical for many engineering applications and some investigations on the traditional composite materials and foams have already been conducted [23][24][25]. This feature is also one of the most significant properties of AMSFs and strongly depends on plateau behavior.…”

Effects of fiber loadings and lengths on mechanical properties of Sansevieria Cylindrica fiber reinforced natural rubber biocomposites

“…These fibers can be used to reinforce composite materials [1,2]. In contrast to more common technological fibers like carbon, glass, and Kevlar [3,4], natural fibers are known for their eco-sustainability [5][6][7]. The impact of adding natural fibers to natural rubber has not been extensively researched.…”
