Fire in the operating theater is a rare but potentially fatal complication. We report igniting an intraperitoneal fire while preforming an exploratory laparotomy for perforated viscus. Fortunately, the patient suffered no injuries as a result.

This publication presents the realisation of a sensor concept, which is based on eddy current testing, to detect textile defects during preforming of semi-finished carbon fibre parts. The presented system has the potential for 100% control of manufactured carbon fibre based components, allowing the immediate exclusion of defective parts from further process steps. The core innovation of this sy...

Modified DNA strands undergo a reversible light-induced reaction involving the intramolecular photodimerization of two appended anthracene tags. The photodimers exhibit markedly different binding behavior toward a complementary strand that depends on the number of bases between the modified positions. By preforming the duplex, photochromism can be suppressed, illustrating dual-mode gated behavior.

This paper aims to show, that the preforming process of parts made of Carbon Fiber Reiforced Thermoplastics (CFRTP) can be improved, when using several technologies like near-net shape cut-piece generation with forming simulation, automated cut-piece detection, robotic gripping and laydown of fabrics. Thereby the authors of this paper want to contribute to the increase of CFRTP applications in ...

Advancing in the process of extending use composites for structural parts applications, it is inevitable to work on complex shapes. That main reason why understanding forming mechanisms and factors put into play during composite materials a major interest both pre-impregnated dry fabric preforming. Thus, appearance defects concern predicting their optimal product quality priority. A great numbe...
