Dataset on open/blind hole-hole interaction in barely visible impact damaged composite laminates

Abstract

This dataset contains the mechanical properties and structural characteristics with images of the carbon fibre reinforced epoxy composite (CFRP) laminates with open/blind holes. The mechanical dataset are the fracture strength, strain at fracture, strain energy density for resilience, strain energy density to fracture and stiffness of the CFRP laminates for different setups (namely 1 hole, 2 holes parallel to applied load, and 2 holes normal to applied load) from pristine and barely visible impact damage (BVID) specimens, determine from in-plane compression test. The structural-related dataset include thermographs, images of BVID specimens, drilling-induced damage BVID specimens and video clips of crack propagation during in-plane compression testing.

In situ resin‐injection approach for repairing barely visible impact damaged carbon‐fiber reinforced epoxy laminates: Optimizing the repair parameters using Taguchi method

“…[ 21,37 ] Furthermore, there was no effect of hole–hole orientation (row of holes parallel/perpendicular to the applied load direction) and hole–hole separation distance (where the VHs were confined within the BVID region) on the mechanical properties. [ 20,22 ]…”

[20,22] Regarding the adhesive used for repairing the cracks, so far epoxy resin has been the main choice. However, it should have noted that the different adhesive types (from different manufacturer) presented in the different studies may have been chemically modified to enhance their adhesive properties.…”

Experimental assessment on the mechanical, physical, thermal, and chemical properties of halloysite and carbon nanoparticles reinforced epoxy resins for repair applications

“…In our previous study, the fiber‐reinforced composite laminates were prone to impact damage when in service (i.e., aircraft taxing on the runway) and also damage that has been induced during maintenance 6,7 . The low‐energy impact damage on composite structure (i.e., carbon fiber reinforced thermoset polymer composite, CFRP) was barely visible to the naked eye but the structural integrity was compromised by about 50% reduction in compression strength 8–12 . To address this issues, several researchers reported that the epoxy resin (also referred to as adhesive) could be used to repair the impact‐type damage on the composite materials by using the resin‐injection method to restore the mechanical properties of the composite materials to its pristine conditions 13–17 .…”
