  1. Structural Self-sensing Based on Measuring the Resistance, Capacitance or Inductance of the Structural <aterial, Without Sensor Incorporation

    06 Nov 2023 | Contributor(s): Johnathan Goodsell

    Structural self-sensing refers to a structural material sensing itself without sensor incorporation. Compared to sensor incorporation, advantages include low cost, high durability, large sensing volume and the mechanical properties being not degraded. The self-sensing ability makes the structural...

  2. Sustainable Manufacturing of Composite Materials

    21 May 2021 | Contributor(s): Johnathan Goodsell

    The growing use of composite materials in aerospace, transportation, recreational products and renewable energy production manufacturing has created a critical need for low-cost sustainable manufacturing methods. The current methods of consolidation and cure are not compatible with the projected...

  3. The Challenges of Determining the Strength of Composites

    24 Nov 2020 | Contributor(s): Johnathan Goodsell

    Why are there such large differences in reported strengths of composites? Some of the reasons are the definition of strength, material variability, poor test methods, and subtle variations in carrying out the tests. But there are other important factors that affect strength that are not...

  4. The Mission, Vision and Programs of the Composites Design and Manufacturing HUB

    08 Oct 2014

    The presentation outlines the mission, vision and programs of the Composites Design and Manufacturing HUB as of October 2014.

  5. The Story of Permeability in Liquid Composite Molding (LCM): How to Devise and Validate Process Simulation Software?

    13 Apr 2022 | Contributor(s): Johnathan Goodsell

    Permeability characterizes the capability of establishing a fluid flow through a porous medium. This lecture aims to present a summary on the state-of-the-art knowledge on permeability in LCM together with a discussion on open questions. The Story of Permeability in Liquid Composite Molding (LCM)...

  6. US-COMP: Next Generation of Composites Materials for Crewed Deep Space Missions

    15 Dec 2023 | Contributor(s): Johnathan Goodsell

    Current state-of-the-art composite materials are not light/strong enough for crewed missions to Mars and beyond. Structural components of deep space vehicles require lighter/stronger materials for fuel efficiency. The NASA Space Technologies Research Institute (STRI) for Ultra-Strong Composites...
