Hybrid composites have gained substantial attention for their ability to address limitations inherent in single-material systems. By integrating fibres, matrices, fillers, or architectures with complementary properties, hybrid composites offer tailored mechanical, thermal, and functional characteristics that are increasingly vital across sectors such as aerospace, automotive, civil infrastructure, marine, renewable energy, and biomedical engineering. Despite their promise, challenges remain in predicting, designing, and manufacturing hybrid systems that perform reliably under complex service conditions.

We are pleased to announce a new platform, Progress of Composite Materials, for researchers, engineers, and industry practitioners in this rapidly evolving field of hybrid composite materials, to present recent breakthroughs, emerging methodologies, and impactful applications that illustrate the unique capabilities of hybrid composites. We invite contributions from that deepen our understanding of how combining multiple constituent materials can deliver enhanced and synergistic performance.

We seek original research articles, reviews, and technical communications that explore the full spectrum of hybrid composite development. Topics of interest include, but are not limited to: advanced material design and hybridization strategies; manufacturing and processing innovations; multi-scale and multi-physics modelling; experimental and computational characterization; durability, damage mechanisms, and lifecycle assessment; optimization frameworks; and novel industrial applications. Studies that investigate new combinations of natural, synthetic, metallic, ceramic, or polymeric constituents, or that integrate digital tools such as machine learning and digital twins, are especially encouraged.

Our goal is to assemble a comprehensive and forward-looking resource that stimulates collaboration and drives further innovation. By contributing to us, authors will play a key role in shaping future directions in hybrid composite research and practice.

We look forward to receiving your submissions and to showcasing the impactful work being carried out in this dynamic and important domain.
