A MICROGEOMETRIC STRUCTURAL MODEL FOR SPREAD TOW FABRIC

Abstract

Abstract: Based on reasonable geometric hypothesis, a two-dimensional geometric structural model of STF composite is proposed. Crimp of fiber tows in the STF can be predicted. An equation of fiber volume fraction of STF composite is also set up, and variation of fibre volume fraction with fiber crimp percentage is analysed. Comparison of the resulting analytical predictions with experimental results shows that the proposed model is valid.

Key words: tow spreading, geometric structure, unit cell, crimp, fiber volume fraction
