1. 제 목 : Drilling of Hybrid Composite Materials
2. 연 사 : 김 대 욱 교수 (워싱턴 주립대학교 조교수)
3. 일 시 : 2006년 7월 14일 (금) 오후 4시 ~ 5시
4. 장 소 : 301동 1512호
5. 내 용 : Today, advanced engineering materials such as composites are being used extensively in the aerospace industry as well as other types of industries due to their specific strength and stiffness. The machining processes of composites are essential to finish the majority of the post-mold manufactured composite parts. Several topics in machining of composite materials will be presented.
Machining of fiber-reinforced plastic (FRP) composites is a challenging task due to their anisotropic natures. In the research, four types of fiber-reinforced plastic composites and hybrid composite materials, namely graphite/bismalaimide-titanium (Gr/Bi-Ti) stacks, graphite/PIXA-M (PIXA-M), graphite/PEEK (PEEK) and titanium/graphite hybrid (TiGr) composites, are used. In order to understand the machining characteristics and mechanisms of composite materials, frequency analysis based on power spectrum and an autoregressive time series model. Through the experimental work, some of the damage problems encountered during drilling hybrid composites include the following: metallic burrs, fiber pull-out, rough surface, cylindricity, and high rate of tool wear. A multi-objective optimization technique and response surface model were used in order to produce the feasible drilling conditions. Drilling force models with an experimental approach are developed in drilling of thermoplastic and hybrid composites. The effect of composite curing processes on machinability and hole quality was found in drilling of composites.
