This SAE Aerospace Standard (AS) defines the requirements for a convoluted polytetrafluoroethylene (PTFE) lined, metallic reinforced, hose assembly suitable for use in aerospace fluid systems at temperatures between -65 °F and 400 °F for Class 1 assembly, -65 °F and 275 °F for Class 2 assembly, and at operating pressures per Table 1. The use of these hose assemblies in pneumatic storage systems is not recommended. In addition, installations in which the limits specified herein are exceeded, or in which the application is not covered specifically by this standard, shall be subject to the approval of the procuring activity.
The present research explores the potential of high-performance thermoplastics, Polymethyl Methacrylate and Polyurethane, to enhance the passive safety of automotive instrument panels. The purpose is to evaluate and compare the passive safety of these two materials through the conduct of the Charpy Impact Test, Tensile Strength Test, and Crush Test —. For this, five samples were prepared in the case of each material via injection moulding, which enabled reliability, and consistency of the findings. As a result, it was found that in the case of the Charpy Impact Test, the average impact resistance varies with PMMA exhibiting a level of 15.08 kJ/m2 as opposed to the value of 12.16 kJ/m2 for PU. The Tensile Strength Test produced the average tensile strength of 50.16 for PMMA and 48.2 for PU, which implied superior structural integrity under tension for the first type of thermoplastic. Finally, the Crush Test showed that PMMA is more resistant to crushes on average than PU with the
Intermetallic Zn-Mo to steel induction brazing was performed in an induction furnace at 1260 degrees Celsius for 0.8 thousand seconds utilising Ni-Cr-Zn filler metal. Base metal atoms such as zinc, molybdenum, and nickel are stated to diffuse to the contact and aggressively react with the filler metal during brazing. This is backed by microstructural research. The reaction layer near Zn-Mo, which is composed of Ni-Cr-Zn compounds and Ni-based solid solutions; the interface's centre zone, which is composed of Ni-based solid solutions with distributed Ni-Cr eutectic phases; and the NiC reaction layer near the steel. The interface is made up of all of these components. The best values for the induction brazing parameters may be calculated by analysing the association between the brazing parameters and the tensile strength of the joints. The joint has a tensile strength of 348 MPa after being brazed at a temperature of 1260 degrees Celsius for 0.8 thousand seconds.
This specification covers an aircraft-quality, low-alloy steel in the form of heat-treated bars and forgings.
This document specifies dimensional, functional and visual requirements for Automotive grade coaxial cable. This material will be designated AG for general-purpose automotive applications or AG LL for low loss applications. It is the responsibility of the user of this cable to verify the suitability of the selected product (based on dimensional, mechanical, electrical and environmental requirements) for its intended application. It is the responsibility of the supplier to retain and maintain records as evidence of compliance to the requirements detailed in this standard.
