Ballistics
Fundamentals: how energy absorption works and which materials are used.
Show moreBallistic body armour reduces a projectile's energy through rigid or flexible material layers. Depending on the application, systems may use ceramics, UHMWPE, aramid or armour steel.
Ballistics
A practical comparison of the two standards and their typical reference levels.
Show moreNIJ and VPAM define different test methods and protection levels. The decisive factors are the expected threat, the specific application and suitable test evidence for the protection system.
Ballistics
From prepreg to finished plate: an overview of one-step and two-step processes.
Show moreA ceramic strike face is combined with an energy-absorbing fibre-composite backing. Material selection, geometry, consolidation process and a uniform bond determine the plate's performance.
Ballistics
Key considerations for private individuals, businesses and public authorities.
Show moreLegal requirements may depend on the product, intended use and purchaser. The full article is currently in preparation and does not replace individual legal advice.
Welding Technology
The essential quality requirements for fusion welding.
Show moreDIN EN ISO 3834 defines quality requirements for fusion welding, including controlled responsibilities, qualified personnel, suitable procedures and traceable documentation.
Welding Technology
Coordinating preheating, interpass temperature and heat input.
Show moreFor high-strength fine-grained steels, preheating, interpass temperature, heat input and filler material must be coordinated. This helps prevent cold cracking and unwanted loss of material properties.
