Compression Tests of Six Curved Paper-Base Plastic Panels With Outward-Acting Normal Pressure

Description: Report presenting results of compression tests of six paper-base plastic panels with outward-acting normal pressure. All panels failed by separation of the skin, either from the rib or from the stiffeners. Results regarding the introduction of air pressure and types of failures encountered are provided.

Effect of Simulated Service Conditions on Plastics During Accelerated and 2-Year Weathering Tests

Description: "The effects of outdoor weathering for 2 years and of an accelerated weathering test on the weight, dimensional stability, and flexural properties of selected reinforced plastics were investigated. The results of all tests, both in this report and the previous report (NACA TN No. 1240), indicate that none of the laboratory aging tests correlated with outdoor weathering with respect to all properties and all materials" (p. 1).

Static and Dynamic Creep Properties of Laminated Plastics for Various Types of Stress

Description: Note presenting creep tests of five laminated plastics to determine the relative creep properties of these materials when subjected to various types of static and dynamic stresses. Results regarding the static tests, repeated stress tests, and creep tests are provided. The results indicated that the relative values of the mechanical properties of the laminates in tension, compression, bending, and torsion are not in the same order for all types of tests.

Mechanical Properties of Five Laminated Plastics

Description: Note presenting results of mechanical tests of several laminated plastics, including canvas laminate molded at low pressure, grade-C canvas laminate, rayon laminate, paper laminate, and glass-fabric laminate. The following tests were performed: static tension, compression, and torsion tests; long-time creep tests at different stresses on specimens loaded in tension; fatigue tests of unnotched specimens in bending; fatigue tests of notched specimens in bending; fatigue tests in bending at temper… more

Impact Strength and Flexural Properties of Laminated Plastics at High and Low Temperatures

Description: Note presenting the Izod-impact strengths and flexural properties of several types of plastic laminates, which are either in use or have potential application in aircraft structures and parts, and were determined at different temperatures. The materials investigated were unsaturated-polyester laminates reinforced with glass fabric and phenolic laminates reinforced with asbestos fabric, high-strength paper, rayon fabric, and cotton fabric.

Tensile and Compressive Properties of Laminated Plastics at High and Low Temperatures

Description: Note presenting a determination of the tensile and compressive properties of several types of plastic laminates, which are either in use or have potential application in aircraft structures and parts, at -70, 77, and 200 degrees Fahrenheit. The materials investigated were an unsaturated-polyester laminate with glass fabric as reinforcement and several phenolic laminates with asbestos fabric, high-strength paper, rayon fabric, and cotton fabric as reinforcements. Results regarding tensile proper… more

Analyses of Decay Curves of Irradiated Plastics

Description: The following report covers the results of a general program that was conducted at the Oak Ridge National Laboratory to investigate the effects on plastic materials of exposure to radiation in the pile. In the investigation, several plastics were irradiated, and on removal from the pile, their rates of decay were determined by measurement of gamma activity in an ionization chamber.

Use of Redux Adhesives for Bonding Metal

Description: Redux is a thermosetting synthetic resin manufactured by the Resinous Products & Chemical Co., Washington Square, Philadelphia 5, Pa. According to the manufacturer, it is intended for bonding metal to metal and metal to wood. It was apparently intended to replace rivets in aircraft structural parts and recent information indicates that a British airplane, the DeHaviland Dove, is in production using this resin. The adhesive was originally developed in England by Aero research Ltd. Experience a… more

Plastics, Their History and Use

Description: Since the civilization, population and living standards of the peoples of the world have increased in such gigantic proportions, especially in the last fifty years; and since the supply of natural resources cannot meet the demand, we have of necessity had to find new materials to take their place. These new materials must fulfill two purposes; namely, to take the place of the natural resources so wantonly destroyed and to meet requirements that the natural materials are not able to meet. Forem… more

The Creep of Laminated Synthetic Resin Plastics

Description: "The long-time loading strength of a number of laminated synthetic resin plastics was ascertained and the effect of molding pressure and resin content determined. The best value was observed with a 30 to 40 percent resin content. The long-time loading strength also increases with increasing molding pressure up to 250 kg/cm(exp 2); a further rise in pressure affords no further substantial improvement" (p. 1)..
