Modelling of Textile Composite Adapted for Roof Structure

Abstract

3D structural components made of fibrous composite materials subjected to service loading are analysed. The laminate consists of a matrix reinforced with a ply of long and unidirectional fibres. Participation of the fibres and matrix can vary in each layer. The main goal is to create a composite roof plate transferring variable loads of wet snow or fir and to investigate its strength properties in respect of (i) the type of fibres and matrix, and (ii) the volume fraction of the matrix and fibres within each layer. Modelling of shape and mechanical properties is reduced to the final phase of structural design, omitting time-consuming, expensive experimental tests. The numerical procedure is solved using the ADINA environment and finite element method code.
