In-operando dynamic visualization of flow through porous preforms based on X-ray phase contrast imaging

Véronique Michaud, Baris Çaglar, Helena Luisa Teixido Pedarros

Direct visualization is often sought to elucidate flow patterns and validate models to predict the filling kinetics during processes whereby a liquid resin infiltrates a textile porous preform. Here, X-ray phase contrast interferometry is evaluated to imag ...

3D Weaving with Curved Ribbons

Mark Pauly, Florin Isvoranu, Francis Julian Panetta, Yingying Ren, Tian Chen, Samuel Jean Bernard Poincloux, Christopher Brandt

Basket weaving is a traditional craft for creating curved surfaces as an interwoven array of thin, flexible, and initially straight ribbons. The three-dimensional shape of a woven structure emerges through a complex interplay of the elastic bending behavio ...

Influence of the stacking sequence on the low-energy impact resistance of flax/PA11 composite

Yann Albert Gérard Lebaupin

In this paper, the low-energy impact behavior of a fully biobased composite made of bio-sourced polyamide 11 resin reinforced with flax fibers was investigated. Different composite laminates were studied in order to determine the stacking sequence effects ...

Assessment of semi-impregnated fabrics in honeycomb sandwich structures

Jan-Anders Edvin Maansson, Véronique Michaud

Semi-impregnated fabrics, or semipregs, are fabrics alternating dry and resin impregnated areas along the fibre bed surface. Due to their increased initial through thickness permeability to gas flow, these could constitute an alternative to prepreg in the ...

Graded glass mat reinforced polypropylene

Jan-Anders Edvin Maansson, Véronique Michaud, Joëlle Wolfrath

In the impregnation process, when pressure is applied, the dry fiber preform is first compressed and then unloads as the matrix flows within the pores. It has been shown earlier that for glass mat-reinforced thermoplastic (GMT) materials, the time to provi ...
