An Approach to Establish Interlaminar Micro Structure of 3-3 Connectivity in Laminated Composites
This article is intended to outline a novel concept of interlaminar 3-3 connectivity of fiber-reinforced laminated composites. This microstructure is typically realized by using thorny ZnO whiskers exactly located in the interlayer of glass or carbon fabric for RTM. From the initial testing, the interlaminar shear strength (ILSS) is noted to increase up to 150% while retaining the most other in-plane properties. Mechanistic penetrating and pinning are considered to be the dominant mechanism of interlaminar toughening effect, with the evidence of the broken, fragmented and pull-out whiskers observed in the fracture morphologies.
