COMPOSITE FOR THE ABSORPTION OF ENERGY

摘要

A composite for the absorption of energy consists of fibers having a breaking length of at least 80 km and an elongation at break of at least 2 %, in particular fibers of a linear polyethylene of ultrahigh molecular weight and carbon fibers or glass fibers, embedded in a matrix. The first fibers are preferably arranged at obtuse angles (+/- (45 ¤& to 90 ¤& )) and the carbon fibers or glass fibers are preferably arranged at acute angles (0 ¤& to +/- 30 ¤& ) to the direction of pressure application in the matrix. The composites may be designed in particular in the form of tubes or corrugated plates.
