Abstract: The invention relates to a method for producing composite elements which have the following layer structure: (i) 2 - 20 mm metal, plastic or wood, (ii) 10 -300 mm plastic, (iii) 2 - 20 mm metal, plastic or wood. The initial materials are introduced in a liquid state for the production of (ii) in at least two steps in the area between (i) and (iii). The area which is to be filled in the last filling step has a volume of 0.1 m3 1.5 m3 and the height which is to be filled is less than 25 mm.

Abstract: A 5-300mm thick plastic layer (2) is sandwiched between two metal layers(1,4), 1-20mm thick. Surfaces of the metal layers facing the plastic have raised areas(3,5) with a height of 0.1-15mm to increase grip between the layers. Raised areas(3,5), preferably 0.1-2mm in height, are produced in the metal layers(1,4) and the metal layers are fixed in position. Space between them is then filled with an initially liquid material to produce a plastic layer(2). The space between the metal layers is sealed to contain the fluid plastic before introduction of the latter. Independent claims are included for a process for manufacturing the composite product in which raised areas or projections are produced by filing, rolling, pressing or grinding.

Abstract: Detecting structural defects in a solid body using vibrations generated within the body by mechanical oscillation, and detecting the acoustic waves emitted by the body with a microphone (12) within the surrounding environment and converted into an electrical signal. Detecting structural defects in a solid body using vibrations generated within the body by mechanical oscillation, and detecting the acoustic waves emitted by the body with a microphone (12) within the surrounding environment and converted into an electrical signal. The signal is analyzed by a computer (16) to determine at least one characteristic value for the vibration behavior of the body, if necessary by subtraction of a background signal and comparison of the characteristic value with a reference value. The reference value is derived from a simulated computation or a comparative measurement. The mechanical vibration is applied by a hammer (11).
