Abstract

The objective of this work is the computational study of composite laminates under high velocity impact loadings. Even with the blessings of modern technology, manufacturing and testing of composites do not always seem to be cost effective. To keep pace with the fast moving global market, a new tool is absolutely necessary that can give reliable results quickly. Over the last decades computational study became a strong and effective tool for the researchers for testing composite materials in a virtual world. The virtual model and the material system of the test specimen can be built in a computer using different modeling software. Finite element analysis is the powerful numerical technique which can be used to predict the behavior of the test specimen under impact loading without incurring the cost and time associated with manufacturing and testing the test specimens. The present study includes analytical investigation of the high velocity impact behavior of ten (10) EG layer woven laminates with and without electrospun nanofibers using LS-DYNA. It was observed that composites with nanofibers in between layers perform better in low velocity impact resistance compared to composites without nanofibers.
