Novel test-rig for compaction behaviour analysis of textile reinforcements for improved RTM-process replication
Abstract
This paper presents anovel testing method for evaluating the compaction behaviour of tex-tile reinforcements inthe context of liquid composite moulding processes. The existing test-ing approach utilizing pre-saturated samples (ex-ante) fails to accurately represent the unsaturated state of samples during vacuum infusion or resin transfer moulding (RTM) proc-esses, leading to unreliable results and potential discrepancies with simulation. To address this limitation, anewly designed test-rig isintroduced in this study, enabling compressibility testing based on real process specifications. The proposed method allows for the measure-ment of both dry and wet compression characteristics using asingle specimen through in- situ impregnation of the materials under compressive load. Moreover, the test-rig enables tests according to ex-ante specifications, facilitating direct comparison with the proposed in- situ method. Finally, the test-rig allows for compressibility tests at elevated temperatures up to 200�C. This isof particular relevance for studying the compaction behaviour of bindered technical fabrics. Preliminary comparative tests demonstrate excellent agreement between the results obtained using the ex-ante method under the 2020 international benchmark exercise and the novel in-situ impregnation method. This confirms the validity and reliability of the results obtained through the proposed testing method. By providing amore realistic representation of the compaction behaviour of textile reinforcements, the novel approach presented in this study offers valuable insights for optimizing liquid composite moulding processes and improving the accuracy of simulation models.
