Abstract
THIS IS PHASE I OF A PROGRAM TO DEVELOP AND EVALUATE NOVEL 4D COMPOSITES CONTAINING NON-ORTHOGONAL FIBER ORIENTATION. A 4D COMPOSITE WILL BE DESIGNED AND FABRICATED WITH IN-PLANE FIBER ANGLES OF 0 DEGREES/ 60 DEGREES PLUS A LOW CONCENTRATION OF THROUGH-THE-THICKNESS FIBERS. THIS CONSTRUCTION SHOULD YIELD A COMPOSITE WITH GOOD TENSILE, COMPRESSIVE AND SHEAR PROPERTIES IN THE PLANE OF THE PANEL COMBINED WITH GREATLY IMPROVED IMPACT RESISTANCE AND DAMAGE TOLERANCE. 4D COMPOSITE PANELS, ALONG WITH COMPARATIVE 2D LAMINATES, WILL BE IMPACTED TO CREATE CONTROLLED DAMAGE, AND THE ENERGY REQUIRED TO INITIATE DAMAGE WILL BE DETERMINED AND THE RESIDUAL COMPRESSIVE PROPERTIES MEASURED. THE RESULTS OF THIS PHASE I PROGRAM SHOULD DEMONSTRATE THAT A NEW AND NOVEL 4D COMPOSITE WILL SOLVE THE CURRENT DAMAGE TOLERANCE PROBLEM WITH ADVANCED COMPOSITES. A PHASE II PROGRAM WOULD EMPHASIZE THE FABRICATION AND TESTING OF PROTOTYPE AIRCRAFT PANELS.
