In April 2016 Manchester eScholar was replaced by the University of Manchester’s new Research Information Management System, Pure. In the autumn the University’s research outputs will be available to search and browse via a new Research Portal. Until then the University’s full publication record can be accessed via a temporary portal and the old eScholar content is available to search and browse via this archive.

Abstract

This project aims to better understand the influence of stacking sequence on the non-crimp carbon fabric composite laminates under low velocity impact and post impact loading. It is also intended to reveal the relationship between the damage characteristics in terms of dent depth, damage length and width and damage tolerance

Layman's Abstract

Carry out impact tests at 3 Joules to 25 Joules to damage samples and analyse their impact behaviours. Obtain the data of damage size by analysing the images generated from Ultrasonic C-scan. Adapt compression after impact tests to understand the relationship between damage characteristics and post impact properties. Conclude and present the influence of ply clustering on composite properties of impact resistance and damage tolerance.
