This feasibility study on composite forming, explores wrinkling issues during draping of non-crimp fabric (NCF) and the possibility of constructing a composite forming limit diagram. The timeliness of the project arises from the urgent need from a wide range of industries to improve their simulation capability for pre-forming of dry fabric and pre-preg. Wrinkling during draping of non-crimp fabric will be measured using the Digital Image Correlation (DIC) method and modelling work will be undertaken using finite element analysis in conjunction with the University of Nottingham. The current research will provide clear guidelines for assessing wrinkle formation. The proposed work complements existing activity within the CIMComp program on forming of composites, providing a framework to fit experiments and modelling of deformation and wrinkling.
The aim of the project is to demonstrate the feasibility of developing a forming limit diagram for textile composites, capturing the limits imposed by defects such as macro-wrinkling, tow level buckling and yarn sliding.
The key objectives of the project are to
Hexcel and Dassault Systèmes. Benefits to industrial partners will include better understanding of the mechanical properties and performance, more opportunity for application of these materials across industry sectors, a wider range of materials and forming situations.
