| 제목 | Interfacial Evaluation of Ultraviolet (UV) Cured Sizing Agent Treated E-Glass Fiber/Vinylester Composites using Micromechanical Techniques |
| 초록 | Interfacial control based to Ultraviolet (UV) radiation and their micro-analysis is very important parameter. UV curing is basically composed of base polymer, non-solvent, diluent and photoinitiator. UV curing, i.e., the process of photo-initiated conversion of polymeric materials from a liquid to a solid is a popular alternative to conventional thermal curing in future many applications. Interfacial properties of E-glass fiber/vinylester composites were also investigated using double-matrix composites (DMC) test combined with nondestructive acoustic emission (AE). Optimum UV curing time was established by measuring mechanical properties and interfacial shear strength (IFSS). The surface of E-glass fiber was treated by a sizing agent for UV curing. DMC specimen was composed of E-glass fiber embedded brittle vinylester inner matrix and ductile epoxy support matrix. The fiber fracture and inner and support matrix cracking signals were detected by AE and then they were separated by waveform and FFT analyses. Total mechanical performance and IFSS should be optimized for UV curing composite systems suitably.
