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
