“…The Izod impact test results indicate that the amount of impact energy increased almost twice in polycarbonate laminate in comparison with no interface one. 16 Flexural stresses were found out by conducting the three-point bending test. The transverse direction deflection is extreme as the specimen starts to slip from the experimental setup when the load was increased.…”

“…The bonds created from solvent vapor bonding have strong bonds and have the ability to resist vibrations and can take huge impacts. [14][15][16] Caution must be taken while using the solvent, and proper ventilation and protective measures must be taken to prevent exposure from the solvents and solvent vapors. If not properly handled, there could be emission of hazardous gases and that may result risk for human health.…”

Armed vehicles, improvised explosive device blast‐proof vehicles, require their windshields and windows to be transparent and yet be resistant to high‐velocity impact of splinters. Hence, composite which is of ballistic grade and yet transparent is in real need for all these applications. This study is dedicated to finding a practical solution for using transparent polycarbonate (PC) laminate made using solvent vapor bonding for ballistic applications. The solvent that was proved to be best for solvent vapor bonding of polycarbonate sheets was dichloromethane, as the bond strength was observed to be high from the results of lap shear tensile test. The transparency retention is reasonably high when solvent vapor bonding was used and the toughness has increased near to 50% in comparison with nonlaminated PC. In this study, a polycarbonate laminate with dimensions 150 × 150 × 40 mm made using solvent vapor bonding and is tested with two 9‐mm bullets fired with velocity of 430 m/s from a distance of 5 m. The laminae successfully stopped both the bullets without any back face signature and there was no brittle failure as such, rather delamination happened at interface of laminae since it has essentially absorbed the impact energy of bullet.Highlights Solvent vapor bonding of polycarbonate laminate.

“…136 Damage tolerance of composite structures evaluated under different types of tests like drop weight impact, open-holecompression, open-hole-tension, compression-after-impact, flexure-after-impact tests. [137][138][139][140][141][142][143][144][145][146][147] The compression strength of composite structures is lower than their tensile strength and is more critical and sensitive to impact damage in different applications. Therefore, the compression-afterimpact strength has been chosen to evaluate the damage tolerance of composite laminates.…”

As the use of composite laminates are unceasingly increasing more and more in many applications, the in-depth understanding about the impact response of composite laminates in certain areas like sport, aerospace and automotive has gained more attention of the designers and scientists over the last two decades. The authors have focused to review the impact properties of fibre reinforced composites particularly impact damage tolerance. Impact resistance, damage tolerance, composite failure and methods of assessing damage tolerance are presented. Furthermore, the approaches for improving damage tolerance such as fibre architectures resin system, and hybridisation using either yarn hybridisation or hybrid layers are discussed. In the end, a survey of modelling the impact damage of laminated composites is made by considering the inter-laminar and intra-laminar failures as key point for evaluating the response of laminates under impact loading.

Carbon fiber reinforced areca/sisal hybrid composites for railway interior applications: Mechanical and morphological properties

et al. 2021

The present experimental investigation focuses on the development of Areca/ Sisal/Carbon reinforced epoxy hybrid composites under various stacking sequences and involves the assessment of their mechanical and morphological properties to evaluate their use in some railway interior applications. Nine different combinations of laminates were prepared by using the manual hand layup technique. Mechanical experiments such as tensile, flexural, impact, inter-laminar shear strength and hardness tests were performed and the results envied the positive values which suggest the use of composites prepared in the study to be employed in some railway interior parts. The morphology of the composites was scrutinized using scanning electron microscopy and exposed the proper agglomeration of fibers in the matrix which in turn has influenced better mechanical properties. The experimental results convey that the hybridization of natural and synthetic fibers in polymer matrix would be an exciting prospect to be utilized in some railway interior applications.
