About

Mehdi Hojjati is a leading researcher in advanced composite materials and manufacturing, with a focus on automated fiber placement (AFP) and the structural behavior of fiber-steered composites. His work addresses critical challenges in the design and fabrication of next-generation lightweight structures, particularly for aerospace applications. Hojjati’s major contributions include pioneering the hygro-thermo-mechanical analysis of fiber-steered composite conical panels, a study that has garnered 19 citations for its insights into how environmental and thermal loads affect variable-stiffness composites. He also developed the induced defect layer method to characterize fiber tow gaps—a common defect in AFP-manufactured laminates—providing a systematic approach to assess how robot-induced deposition flaws compromise structural integrity. This work, cited 9 times, is foundational for quality control in automated manufacturing. Hojjati’s research bridges the gap between advanced manufacturing techniques and structural mechanics, offering practical solutions for defect-tolerant design. His achievements are particularly notable for advancing the understanding of AFP-specific defects, a critical area as the industry moves toward fully automated composite production.
