Bending Response

This article investigates the influence of homogeneous and hybrid external patches based on glass and Kevlar plain weave woven fabrics on local bending response of adhesively bonded external patch repairs in damaged glass/epoxy composite laminates. The intent of using hybrid external patches was to combine the excellent high displacement to failure property of Kevlar fiber as a ductile reinforcement with the superior mechanical property of glass fiber as a brittle reinforcement. The undamaged normal specimens were taken as the standard specimen for evaluation of residual mechanical properties. In all hybrid patches, the proportion of Kevlar and glass fibers was equal (i.e. 50% of Kevlar and 50% of glass by volume fraction), while lay-up configurations were different. This further allowed studying the associated effects of hybridization and lay-up configuration on local bending response of the repaired laminates. All the specimens were subjected to cyclic quasi-static indentation tests with a step loading method. The indentation tests have also been monitored in real time by acoustic emission system. The acoustic emission results illustrated various damage profiles and correlates with the mechanical test results to point out the load to a transformation in damage mechanisms during indentation loading with respect to the effect of each patch material on the performance of the repaired glass/epoxy specimens. Results showed that hybridization and lay-up configurations of the external patches played a significant role on local bending response (i.e. ultimate load, stiffness, residual deformation, displacement to failure, and damage pattern) of the repaired glass/epoxy specimens. Specimens repaired using intra-ply hybrid patches showed the best local bending response.

Use of composite laminates is found in various applications such as aircraft and automotive, sports, rocket parts and civil structures. Resin system of the polymer composites enacts a crucial role of binding the reinforcements properly to provide good mechanical properties. The presence of any kind of filler alters the properties of resin system which in turn also alters the mechanical behaviour of composite laminate. In the present work an attempt has been made to enhance the mechanical performance of glass fibre epoxy composites by embedding nano calcium carbonate particles in resin system. These particles were added in different weight fractions like 1, 3 and 5% and the response of GFRP nano composites were recorded under flexural and shear loads. Composite laminates with 3% wt. of nano particles have shown considerable improvement among the other laminates.
