Spring-in of composite L-shape specimens: An experimental and numerical investigation (2023)
Journal Article

The effect of stacking sequence, specimen thickness, tooling material and curing cycle on process induced distortions of L-shape composite structures is investigated experimentally and numerically. Sixty specimens were manufactured, and their spring-... Read More about Spring-in of composite L-shape specimens: An experimental and numerical investigation.

Benchmark exercise on image-based permeability determination of engineering textiles: Microscale predictions (2023)
Journal Article

Permeability measurements of engineering textiles exhibit large variability as no standardization method currently exists; numerical permeability prediction is thus an attractive alternative. It has all advantages of virtual material characterization... Read More about Benchmark exercise on image-based permeability determination of engineering textiles: Microscale predictions.

Controlling resin flow in Liquid Composite Moulding processes through localized irradiation with ultraviolet light (2022)
Journal Article

A vacuum infusion process was implemented to produce composite specimens from a random glass filament mat and an acrylic modified polyester resin curable upon irradiation with ultraviolet (UV) light. Through localized irradiation with UV light during... Read More about Controlling resin flow in Liquid Composite Moulding processes through localized irradiation with ultraviolet light.

Bayesian inversion algorithm for estimating local variations in permeability and porosity of reinforcements using experimental data (2021)
Journal Article

Efficient meshing technique for textile composites unit cells of arbitrary complexity (2020)
Journal Article

Meso-scale unit cell models are often used to simulate mechanical behaviour of textile composites. Apart from reliable ways to create meso-scale geometries, such simulations require reliable meshing algorithms. While the former is made possible via d...

Experimental and numerical investigation of interface damage in composite L-angle sections under four-point bending (2020)
Journal Article

© The Author(s) 2020. Curved laminates in aero-structures, such as the L-angle sections where webs and flanges meet, are prone to delamination due to high interlaminar stresses in these regions. Some efforts to investigate delamination in these struc... Read More about Experimental and numerical investigation of interface damage in composite L-angle sections under four-point bending.

A numerical study of variability in the manufacturing process of thick composite parts (2018)
Journal Article

Experiments show that different processing conditions lead to different levels of compaction and variability in the thickness. This paper presents an analysis of processing conditions and their effects on consolidation of thick composite components....

Effect of yarn cross-sectional shape on resin flow through inter-yarn gaps in textile reinforcements (2017)
Journal Article

Axial flow through gaps between aligned straight yarns with realistic cross-sectional shapes, described by power-ellipses, was analysed numerically. At a given fibre volume fraction, equivalent gap permeabilities have a maximum at minimum size of elo...

Effects of layer shift and yarn path variability on mechanical properties of a twill weave composite (2016)
Journal Article

Experimental and numerical analysis of a woven composite were performed in order to assess the effect of yarn path and layer shift variability on properties of the composite. Analysis of the geometry of a 12K carbon fibre 2×2 twill weave at the meso-... Read More about Effects of layer shift and yarn path variability on mechanical properties of a twill weave composite.

Digital image correlation vibrometry with low speed equipment (2016)
Journal Article

A low-cost method is presented which enables digital image correlation (DIC) with conventional cameras (i.e. not high-speed) to be used for determination of vibration deflected shapes via the use of a stroboscopic lamp and some simple ancillary circ...
