Towpreg Production
Many customers see value in acquiring in house production of towpreg which is used either for filament winding or automated towpreg placement processes. Mikrosam’s customized solution for towpreg production reduces the total cost of production and resolves many questions related to logistics and provides higher process and material quality control. It can be used with any fiber reinforcement and any commercially available or proprietary hot-melt resin systems.
