Advanced Composites Data for Aircraft Structural Design. Volume 1: Material and Basic Allowable Development - Boron/Epoxy.
Abstract
This volume summarizes the determination of material properties for a specific epoxy resin and glass scrim cloth, the determination of the effects of nuclear blast on the strength of a composite laminate, and the assessment of existing micromechanics techniques for the prediction of composite lamina characteristics. All efforts in this program were relative to a specific boron/ epoxy composite material system known commercially as Narmo Rigidite 5505. A procurement and a process specification were established during the program and have demonstrated a capability to produce satisfactory material consistently. Tests are described for a program to characterize separately Narmco 2387 resin and 104 glass scrim cloth. Test data are presented for standard mechanical properties and elastic constants at both room temperature and 350 F. A test program to determine the effects of nuclear blast on boron/epoxy laminates is described and test data are presented. An evaluation is presented to show the degree of validity of several micromechanics techniques for predicting composite lamina characteristics from known properties of the constituents.
