Abstract: Disclosed herein is an energy-absorbing component for absorbing energy of impacts thereon, where the energy-absorbing component can be plastically deformed by an impact and optionally can undergo at least some extent of destruction. The energy-absorbing component contains at least one core structure and at least one ancillary structure. The at least one core structure is manufactured from a first material which is a metal or is a polymer reinforced with continuous-filament fibers, and the at least one ancillary structure is manufactured from a second material which is an unreinforced polymer material or is a polymer material reinforced with short fibers or with long fibers. The at least one ancillary structure may include ribs and may be bonded to at least one core structure, so that the at least one ancillary structure supports the at least one core structure connected thereto. Processes for producing the energy-absorbing component are also disclosed.

Abstract: The present invention relates to a consolidated nonwoven consolidated by treatment with an aqueous binder composition comprising:
a polymer P,
a polyvinyl alcohol,
optional a starch compound S and
optional at least one metal compound M selected from the group consisting of magnesium, calcium and zinc, in the form of an oxide, hydroxide, carbonate or bicarbonate,
wherein the polymer P is obtainable by free radical aqueous emulsion polymerization of a monomer mixture of
75 to 99% by weight of one or more monomers a) selected from the group consisting of esters of acrylic and/or methacrylic acid with alkanols of 1 to 12 carbon atoms, aliphatic conjugated diene and aromatic vinyl compound
1 to 25% by weight of one or more monomers b) selected from the group consisting of N-methylolacrylamide, N-methylolmethacrylamide, glycidyl methacrylate and carboxylic acid-functional ethylenically unsaturated monomers
≥0 to 15% by weight of one or more further ethylenically unsaturated monomer c) different from any of monomers a) and b)
wherein the amounts of monomers a) to c) sum to 100 wt %,
the water-based binder composition, the process of for producing the consolidated nonwoven and its use as reinforcing insert for bituminized roofing membranes.
