Impact Characteristics for Composite with Initial Delamination
층간분리가 있는 복합재료의 충격특성
- Published : 2005.04.29
Abstract
In order to evaluate impact characteristics for the laminates with or without delaminations, carbon fiber/epoxy laminated composite were fabricated. After trying several ways to develop delaminations within the laminates, an insertion of teflon-tape was found to be most effective. The locations for delamination was determined after several trial-and-error experiments. The low impact energy did not produce measurable difference for composites with or without delamination, which indicated the presence of impact energy threshold. The impact chacteristics for composites with the delamination were found to be different from those for composites with other type of defect including fiber failures.
