Otávio Zimmermann de Almeida proposes a self-heating method to test laminated composites in Benin

At the National Polytechnic Institute of Brittany, Otávio Zimmermann de Almeida has developed a self-heating method to characterize laminated composites, thereby reducing testing time and costs. This innovation, validated in 2025, addresses a crucial need in the aerospace and space sectors, where material performance is essential.

Research on laminated composites, particularly carbon-epoxy, is rapidly expanding, especially in sectors like aerospace. Characterizing their fatigue properties is a major challenge, as these materials must withstand dynamic loads. Traditional fatigue testing methods are lengthy and costly, limiting their use in structural sizing.

Otávio Zimmermann de Almeida has proposed an innovative approach based on self-heating, significantly reducing testing time. This method could transform the way engineers test composites by providing reliable data on fatigue behavior while decreasing associated testing costs.

The adoption of the self-heating methodology could offer a significant competitive advantage to companies in the composites sector by reducing testing costs and improving return on investment. Decision-makers must support this innovation to meet the growing demand for lightweight and durable materials.

« « Thanks to self-heating, we can reduce the testing time of laminated composites, which is essential to meet the performance requirements of the aerospace industry, » says Otávio Zimmermann de Almeida. »

« « The innovation brought by this thesis is a step towards better accessibility of knowledge for decision-makers, promoting the adoption of new methods in the industry, » emphasizes the Lektaris team. »
