Analysis of roller compaction pressure distribution in automated dry fibre placement (2023)
Journal Article

Automated Dry Fibre Placement (ADFP) is a version of Automated Fibre Placement (AFP) where prepreg tapes are substituted with dry fibre tapes. In this process, a uniform compaction pressure applied by a compaction roller is required to manufacture pr...

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.

Recent progress, challenges and outlook for multidisciplinary structural optimization of aircraft and aerial vehicles (2022)
Journal Article

Designing an airframe is a complex process as it requires knowledge from multiple disciplines such as aerodynamics, structural mechanics, manufacturing, flight dynamics, which individually lead to very different optimal designs. Furthermore, the grow... Read More about Recent progress, challenges and outlook for multidisciplinary structural optimization of aircraft and aerial vehicles.

Design guidelines for hybrid continuous/discontinuous carbon fibre laminates (2022)
Journal Article

Combining discontinuous carbon fibre moulding compounds with unidirectional (UD) non-crimp fabric has been studied as a potential solution for producing cost effective composite structures, with short cycle times via compression moulding. The tensile... Read More about Design guidelines for hybrid continuous/discontinuous carbon fibre laminates.

Weft Yarn Interlacement Modelling for 3D Profiled Structures (2021)
Journal Article

Currently, generation of 3D woven T-joint models with complex weave geometries, using TexGen software, is a manual process. One of the main challenges to automatic generation of these textiles is the order in which the weft yarns interlace within the...
