Synthetic Resins in Aircraft Construction - Their Composition, Properties, Present State of Development and Application to Light Structures
This is a 1937 NASA technical report on synthetic resins for aircraft construction, covering their composition, properties and use in light structures, written for aeronautical engineers. Its single picture is a technical chart plotting compressive strength and specific weight of a resin against percentage of wood flour, which a designer might take as a plain example of how a filler changes material properties.
