- HIGHLIGHTS
PREPREGS - PREimPREGnated materials - are fiber fabrics impregnated with reaction resin compounds. With a wide range of options for further processing, they represent the ideal basis for light and high-strength construction parts.; The Krempel-PREPREG systems are based on reactive resins with a curing system that is latent at room temperature and highly reactive at elevated temperature.; Initially, the PREPREG resins are in the reactive B-stage with medium to high viscosity. The problem-free further processing takes place through the supply of energy and simultaneous shaping measures. The low molecular weight, still meltable resins are converted into the high molecular weight, infusible C-state. For this controlled process, we tailor the resin system exactly to the specifications of the processor.; In conjunction with glass, carbon and aramid fibers can be structural components with excellent properties produce. By adding additive dyes and fillers, application-specific properties can be specifically adapted to the respective conditions.; For plastic mold making , Krempel offers comprehensive engineering services as well as tried and tested design solutions right through to ready-to-use tooling. The BX card PREPREG system in particular has numerous advantages:; Tempering in the demolded state (after hardening at 55 ° C); Autoclave cycles with low temperature and low consolidation pressure; Use of inexpensive model materials; Hardening cycles with different temperature control; High number of cycles when used as a tool
