Investigation of Core Node Separation and Crush

Abstract:

Article Preview

The causes of the honeycomb core node separation/core crush defects of fiberglass sandwich panel is analyzed. The porosity of skin and leakage of vacuum bag under high-pressure curing environment are identified as root causes based on the analysis of historical data and designed simulation testes, and approved by statistic analysis calculation also. The relationship of core thickness and the opportunity of the defects appearing are discovered by tests.
