American Society for Composites

Established in 1985, the American Society for Composites (ASC) aims to provide a communication forum for the engineering and scientific community in composite materials. The society was formed to expedite the growth of knowledge gained from interdisciplinary engineering and scientific research in composite materials and to promote the exploitation of the unique properties of composite materials in emerging applications.

For over 40 years, the American Society for Composites (ASC) has been an organization dedicated to advancing the science and technology of composite materials and structures. As an all-volunteer group composed of dedicated professionals in academia, industry, national laboratories, and federal agencies, we aim to serve as the pre-eminent focal point for the technical exchange of ideas, building networks and relationships, and facilitating communication amongst individuals having a mutual interest in composites. Each year, the annual technical conference in the Fall takes place over three days with 250+ papers. Conference typically has seven parallel sessions with each paper given a presentation time of 25 minutes. ASC has a no-paper/no-podium rule for its annual meetings.

Wednesday Workshop

Best Practices and Lessons Learned for Applying Continuum Damage Mechanics to Aerospace Structures

October 8, 2025

Session 1

Introduce individuals who are new to continuum damage mechanics (CDM) or progressive damage and failure analysis (PDFA) to the terminology, approaches, and resources. Disseminate the broad knowledge related to the verification, validation, evaluation, and application of CDM and PDFA methods developed under United States government funded research programs.

Session 2

Walk students through the process of building a finite element model for a continuum damage mechanics analysis, explaining the concepts and past studies that have led to our best practices. Finish with examples that demonstrate the importance of some of the best practices.

10 years of IACMI-The Composites Institute – Enabling US Competitiveness in Advanced Composites Technologies

The Institute for Advanced Composites Manufacturing Innovation (IACMI)-The Composites Institute was established in 2015 under the sponsorship of US Department of Energy (DOE). IACMI’s mission since its founding is to enhance US competitiveness in value-added Advanced Composites Technologies at Technology Readiness Level(s) of 4-7. IACMI in partnership with its 170+ members has executed over 60 industry led projects connecting the supply-chain in automotive, wind, gas storage, infrastructure, aerospace and related sectors. Diverse range of projects have included, (but not limited to) – low cost carbon, hybrid natural (bio-based) fiber reinforcements, sustainable composites, tooling and preform innovations, high-rate manufacturing of continuous and discontinuous fibers, joining/assemblies, life cycle analysis, reduced embodied energy, simulation informed manufacturing etc. IACMI has also championed major Work Force Development (WFD) initiatives at the K-12, community colleges and industry training in advanced composites through sponsorship of Department of Defense (DoD). The presentation will cover the 10-year evolution and impact of IACMI, challenges, gaps and opportunities, key accomplishments, representative projects, technology roadmap, industries served and path forward.

Dr. Dennis Butcher

Dr. Dennis Butcher is the Deputy Branch Chief for the Polymer Matrix Composites Branch Lead and the Lead for Additive Manufacturing of Composites for Limited Life Aircraft Structures, Air Force Research Laboratory, Composite, Ceramic, Metallic, and Materials Performance Division. In this role, Dennis leads development efforts to mature additive manufacturing materials and processes for structural application in small UAS, collaborative aircraft, and munitions. These efforts focus on maturing agile, adaptable, and scalable manufacturing solutions to deliver affordable mass.

 

Dennis joined the Air Force Research Laboratory in 2012 as a post-doctoral research scientist in the Soft Matter Materials Branch, where he worked to improve light absorption in organic photovoltaics cells and engaged in efforts to enable flexible, stretchable, and reconfigurable electronic circuits by utilizing liquid metal alloys. In 2014, AAAS selected Dennis for the AAAS Science and Technology Policy Fellowship program, where he served as an International Program Officer at the Air Force Office of Scientific Research (AFOSR). While there, he developed cooperative basic research programs with foreign research funders and identified USAF relevant investigators to link to AFOSR programs. Starting in 2014, Dennis served as the Government Program Manager for America Makes, the National Additive Manufacturing Innovation Institute in the AFRL Manufacturing and Industrial Technologies Division. Dennis supported the America Makes mission to accelerate the adoption of additive manufacturing in the US industrial base by managing the government relationship with America Makes, socializing the Institute among government SMEs and acquisition offices, streamlining the ability of agencies to contract with America Makes and its members, and providing technical and programmatic oversight.

Composites Additive Manufacturing: A Path to Affordable Mass

 Composites Additive Manufacturing, and particularly Continuous Fiber Additive Manufacturing (CFAM), are emerging technologies with vast potential to change the ways we design, fabricate, and field composite structures.  The Department of the Air Force (DAF) requires the ability to deliver affordable mass across a variety of systems and products to counter peer adversary threats.  These systems will need to do more, cost less, and address diverse and dynamic mission profiles that are not easily supportable with existing supply chains, design methodology, and fabrication practices.  This talk will explore Air Force Research Laboratory efforts to mature agile, adaptable and scalable CFAM solutions as a means to deliver affordable mass, pull lessons from the successful deployment of mature polymer and metal additive manufacturing processes, and propose a path forward for collaborative development across industry, government, and academia.
