- Such a fiber composite material is particularly suitable as an automotive component.
- Such fiber composites have several advantages over steel, so they are lighter, are characterized by an improved crash resistance and are also more durable.
- DER331 (Dow Chemical, epichlorohydrin liquid epoxy resin and bisphenol A) and a catalyst composition were mixed for 30 seconds at 2000 rpm in a vacuum in the Speedmixer. After cooling this mixture to RT, methylene diphenyl diisocyanate (MDI) was added and also blended for 30 sec at 2000 rpm in a vacuum using a Speedmixer. The reaction mixture was poured into an upright mold and gelled at RT. Thereafter, the mixture was cured in two stages (1 h at 90 ° C and 1 h at 150 ° C). After cooling, the specimens required for the mechanical tests are milled from the resulting plate.
- MDI methylene diphenyl diisocyanate
