Abstract

Abstract Translated from German Zur Erzielung eines möglichst geringen Gewichts ist der Bolzen (B) als Verbundkonstruktion mit einem Kern (K) aus füllstoffverstärktem Kunststoff und einer metallischen Umhüllung (H) ausgebildet. Als Füllstoff werden Quarzsand oder Kohlefasern verwendet. Die Umhüllung sitzt vorzugsweise unter Umfangszugvorspannung auf dem Kern. Die Herstellung des Bolzens erfolgt z.B. durch Einpressen von Füllstoffen und Matrixharzsystem direkt in der entsprechend vorbereiteten Umhüllung. To achieve the lowest possible weight, the bolt (B) is designed as a composite construction with a core (K) made of filler-reinforced plastic and a metallic covering (H). Quartz sand or carbon fibers are used as fillers. The sheath is preferably seated on the core under circumferential tension. The bolt is manufactured, for example, by pressing fillers and the matrix resin system directly into the correspondingly prepared casing.
