Failure Prediction Analysis of Hybrid Resin Composite Materials by Using Weibull Analysis

Abstract

Carbon fiber reinforced composite materials are extensively utilized as structural components in aerospace applications owing to their specifically customized characteristics. The assessment of the materials relies on their characteristics and how they perform when subjected to various types of loads. The objective of this study is to explore the optimal blend of various Bifunctional and Multifunctional epoxy resins in order to attain enhanced characteristics. Five variations of a blend are being considered, with varying percentages of two components 20:80, 40:60, 50:50, 60:40, and 80:20. Utilizing the Weibull distribution, a statistical analysis was conducted on experimental data obtained from NOL ring studies. This analysis resulted in the formulation of a mathematical model for predicting the failure of hybrid resin composite materials under hoop tensile loading conditions. Using tensile tests and constructing distribution curves, researchers identified the properties of failure stress within the Weibull distribution. A critical vulnerability has been identified in the 50:50 hybrid resin combination of the composite material, with predictions suggesting a high likelihood of failure.
