Welcome to SACL!
Welcome to the Structures And Composites Laboratory (SACL) in the Department of Aeronautics & Astronautics at Stanford University. The main focus of the group is to build intelligent and light-weight structures, with emphasis on structural health monitoring.
Areas of Research Focus:
Structural design to enhance vehicle safety, performance, reliability, and sustainability
Manufacturing to improve material quality, process control, and fabrication costs
Smart materials to create innovative structural designs including structures with multi-functional capabilities
Health monitoring for ground vehicles, aircraft, and spacecraft structures
Design methods, prototypes, and tools to transform and develop technologies to reach and benefit the general public

SACL won "Most Practical SHM Solution for Aerospace" Award in IWSHM2015
The Structures and Composites Laboratory (SACL) of the Aeronautics and Astronautics Department at Stanford University won the "Most Practical SHM Solution for Aerospace" Award in the International Workshop on Structural Health Monitoring 2015 (IWSHM 2015) that was held in September 2015 at Stanford University! The award is sponsored by AIRBUS and the participants were reviewed by a panel of representatives from academia, industry, and government.
The SACL team presented a live demonstration of a novel bio-inspired smart composite wing with state sensing and awareness capabilities for the next generation of “fly-by-feel” UAVs! Sensor networks, consisting of piezoelectric, strain, and temperature micro-sensors, were developed and monolithically embedded in the carbon fiber layup of the wing to enable self-sensing capabilities. Advanced system identification, signal processing and diagnostic algorithms were developed and employed to accurately interpret the sensing data in real time and monitor the wing aerodynamic loads and structural health state. During the demo a live video connection was established with the Stanford wind tunnel and data from the wing were collected and processed in real time during "blind test" experiments! Then, using an in-house designed software with the integrated algorithms the SACL team was able to identify the actual structural/aerodynamic and health state of the wing that was indeed in agreement with the live experiments. The live demonstration was successful and the committee awarded the SACL team the first prize!
