|
 | A comprehensive investigation was performed to determine the physical, chemical, and mechanical properties of thermally degraded plastic ablation materials. Several new experimental techniques were developed and some existing techniques were modified to obtain the desired information. Deductions from experimental results provide new information on ablation phenomena. (Author) |

|
| A review of the status of extreme temperature range (ETR) coolants for electronic equipment is presented. The fluids considered for use over a -80 F to 400 F temperature range are described in this report and fall into the following class of compounds: amines, chlorofluoro-carbon oils, fluorochemicals, silicones, silicate esters, and siloxanes. Results show that the silicone fluids comply most closely to the physical properties required for ETR electronic coolants. ... |

|
| Two improved types of nylon yarns (1) Type 330, 30 denier, a more UV radiation and heat resistant yarn and (2) Type 300, 30 denier, a higher strength than the conventional nylon yarn, were developed to be used in materials for personnelAND OTHER TYPE DECELERATORS. Cloth, woven of the 2 types of nylon yarn, in both natural and International Orange were exposed to (1) outdoor weathering, (2) accelerated aging and ... |

| A BENCH SCALE METHOD FOR DETERMINING PERFORMANCE CHARACTERISTICS OF LUBRICANTS IN AN OXIDATIVE ENVIRONMENT AT HIGH TEMPERATURES |
DEC 1960 |
|
| Authors:
SAMUEL B. SCHEXNAILDER; NOISE REDUCTION PANEL LONDON (ENGLAND)
|
| An effective bench scale method for determining physical and chemical characteristics of lubricants subjected to high temperatures in oxidizing environments is described herein. The apparatus employed is sufficiently simple and economical for even the smallest research facility. However, the methods developed and described herein are applicable for large scale programs. Data obtained from its use can be readily interpreted to indicate probable performance of experimental fluids and lubricants under the ... |
