Enhancement in Interply Toughness of BMI Composites Using Micro-Thin Films

Nowadays, laminated composites are widely used in the aerospace sector. All laminates have interply/interlaminar interfaces even if they made using automated processes. The act as areas of weaknesses and potential crack initiation regions. Hence, any enhancement propagation resistance is always sought after. Usage polymeric thin films one promising viable ways to achieve this. It also easy incorporate micro-thin into automation process. In present study, different customized that compatible with Glass/BMI fabricated. Fracture toughness tests Mode I (opening mode), II (sliding mode) Mixed I/II conducted respectively Double Cantilever Beam (DCB), End Notch Flexure (ENF) Bending (MMB) test specimens. This paper discusses manufacturing films. various challenges faced during incorporation presented. results fracture examined. Mechanisms through which help resisting deliberated discussed. this technique Automated Fiber Placement (AFP)
