Horizontal shear testing of woven fiberglass/epoxy composites /

In this program horizontal (apparent) shear data from a number of quality control efforts were compiled and augmented by additional tests. The data were used to show the effects of test parameters, cure conditions, and material age on the apparent shear. Failure modes were recorded. Findings include: (1) Based on the horizontal shear test, CE 9000 (Ferro Corp.) should not be postcured above 370 F, and the desirability and effects of a postcure between 350F and 370F should be explored before committing to this postcure condition. (2) Autoclave cure of CE 9000 will increase its resin dominated shear properties 50% or more, compared to vacuum-bag, oven-cured parts. An appreciable drop in apparent shear using the short beam method occurs as S/t6 is increased. Data should be normalized to a consistent S/t for comparison. (3) The predominant damage pattern for woven glass coupons is related to S/t and the degree of cure. (4) Certain woven glass composites require an S/t well below 5 to achieve shear failure. (5) Short beam specimens of the type investigated should be fabricated with peel plies or porous release cloth on both sides.Research supported by the United States Air Force Wright Aeronautical Laboratories."Final Report for Period January 1979 - April 1982.""October 1983."Includes bibliographical references (page 42).In this program horizontal (apparent) shear data from a number of quality control efforts were compiled and augmented by additional tests.

Hypersonic dynamic stability.

The report presents a summary of the important results obtained on a combined analytical and experimental program for investigation of the hypersonic dynamic stability of re-entry vehicles. An unsteady flow field solution is described which predicts the static and dynamic stability characteristics for vehicles which are executing small amplitude oscillations about zero angle of attack. Solutions were obtained for sharp and blunted, axisymmetric and two-dimensional shapes in real gas equilibrium flow. The experimental program was conducted in AEDC tunnel 'C' at Mach 10 and in the Ling-Temco-Vought Hot Shot tunnel at Mach 14 and 20 to obtain dynamic stability characteristics of a 10 degree cone. Data are presented to show the effect of bluntness ratio, reduced frequency, center of gravity location, Reynolds number and Mach number. Comparisons are made with various theoretical results and limited correlations are shown which establish significant trends.AD0650794 (from http://www.dtic.mil)."January 1967."Includes bibliographical references (pages 81-82).The report presents a summary of the important results obtained on a combined analytical and experimental program for investigation of the hypersonic dynamic stability of re-entry vehicles.
