Extension of Puck's inter fibre fracture (IFF) criteria for UD composites

Self-Sensing Composites: In-Situ Detection of Fibre Fracture

The primary load-bearing component in a composite material is the reinforcing fibres. This paper reports on a technique to study the fracture of individual reinforcing fibres or filaments in real-time. Custom-made small-diameter optical fibres with a diameter of 12 (±2) micrometres were used to detect the fracture of individual filaments during tensile loading of unreinforced bundles and compos...

Effect of inter-laminar fibre orientation on the tensile properties of sisal fibre reinforced polyester composites

In this present work, effects of interlamina fibre orientation on the tensile properties of composites were studied and the results were discussed. The varying types of fibre oriented composites were prepared using the compression moulding technique at a pressure of 17 MPa. The different types of oriented composites investigated were 90o/0 o /90 o, 0 o /90 o /0 o, 90 o /0 o /0 o /90 o, 0 o /45 ...

Influence of fibre-matrix interface on the fracture behaviour of carbon-carbon composites

This paper studies the fracture behaviour of unidirectional carbon fibre reinforced carbon matrix composites and its relation with the type of fibre-matrix interface developed in the composite. Model unidirectional carbon-carbon composites were prepared using the same type of fibre and different pitches as matrix precursors. These included both commercial pitches and synthesized in the laborato...

The Fracture of Glass-Fibre Reinforced Epoxy Composites using Nanoparticle-Modified Matrices

Non-smooth mode I fracture of fibre-reinforced composites: an experimental, numerical and analytical study.

We present a novel approach to analyse the fracture of fibre-reinforced composites. Experimental results on mode I fracture of glass fibre and carbon fibre unidirectional laminates presented here and published by others in the open literature formed the basis for the analytical and numerical results presented. When details of the external loading rate are explicitly accounted for, a new picture...
