Vanessa Kwiatkowski optimizes thermoplastic composites for aerospace at IRDL

Vanessa Kwiatkowski, from the National Polytechnic Institute of Brittany, has developed a sizing method for thermoplastic composites, revealing that the orientation of the specimens can influence fatigue life by up to 30%. This research, supported by IRDL, addresses an urgent need in the aerospace sector for more reliable and durable materials.

Research on thermoplastic composites, particularly those reinforced with short fibers like PEEK CF30, is booming in aerospace. Despite their light weight and strength, their fatigue behavior, especially under compression, remains poorly understood. Vanessa Kwiatkowski has conducted work to characterize the fatigue life of these materials, thus filling a gap in the scientific literature.

The results of the thesis show that the orientation of the specimens and the load ratio significantly impact fatigue life. Tests revealed that variations in orientation can lead to performance differences of up to 30% in fatigue resistance, highlighting the importance of a systematic approach based on experimental data.

This research opens strategic perspectives for the aerospace sector, where the demand for lightweight and durable materials is growing. Decision-makers must support research projects to generate reliable data on the fatigue behavior of composites, in order to minimize risks and maximize return on investment in this rapidly expanding market.
