文件大小: 67KBThe aluminium alloys EN AW-7020 of the sys-tem Al-Zn-Mg and EN AW-6082 of the system Al-Mg-Si were chosen for the experiments. The last material belongs to the 6xxx-series wise at most medium-strength aluminium alloys. However, the EN AW-6082 has the greatest quantity of alloying com-ponents and possesses the greatest strength from the
Aluminum Alloy Zinc EN AW 7021 is especially recommended for the following applications: Resin transfer molding, Compression molding, Resin injection molding, Blow molding, Thermoforming. The main alloy addition is zinc and is formulated for primary formation in forged products, it is not recommended for complex shapes and sharp corners.
The IADC Space Debris Mitigation Guidelines15 are the only remedial scheme yet produced with a significant positive effect on space debris accumulation. The guidelines aim to mitigate the adverse consequence of space debris by identifying and pub-lishing known ways to mitigate space debris.16 However, the guidelines only reduce the amount of ...
impact features on aluminum foils was reported by H ˆrz et al. (1993). Where recognition of particle origins is an important goal for an impact survey (e.g., Kearsley et al. 2005), confusion of the substrate compos ition with that of impacting space debris may be a problem, unless a substantial amount of residue is present (Graham et al. 2004).

An impact detection and remediation system includes a sensing device for detecting damage events related to a structure of interest. Such damage events may include impact from a ballistic object, a tamper event, a physical impact, or other events that may affect structural integrity or cause failure. Illustratively, the sensing device is in communication with a measurement

I can imagine lightweight semi-permanent disablement by spraying paint on lenses and wrapping the entire craft in aluminum foil. Zero space debris, and not even destruction of property. This takes more fuel and an advanced robot craft, but should be preferable for a time when a fast all-out war is not being fought.

Jan 30, 2020 Space debris can be divided into two categories: (a) space debris falling to the Earth, either generated during a launch in the Earth's atmosphere or re-entering the Earth's atmosphere from outer space; and (b) space debris in orbit. The latter category is known as “orbital space debris” (IAA, 2005, p. 6).
