HexPly + TEXIPREG
HexPly® and TEXIPREG® prepreg systems
HexPly® and TEXIPREG® are fabrics and Non-crimp fabrics made of glass, carbon and aramid fibres impregnated with epoxy or phenolic resins. Different resin systems are available depending on the requirements of the finished component and selection of the suitable process. Important parameters when selecting the right resin system are, for example, thermal and mechanical properties of the cured material, flowability, curing temperature and curing time, tack, shelf life, etc. Prepregs must be stored deep-frozen and always in an airtight plastic bag. Before processing, the prepreg must be thawed in the closed bag at room temperature for at least 12 hours. Do not open before!
Shelf life at -18°C: 12–18 months, depending on the resin system.
Processable at 20°C: 7–60 days depending on the resin system.

Mould making prepreg HexTool®
HexTool® is a millable tooling prepreg for toolmaking and meets the highest requirements for dimensional accuracy and durability. HexTool moulds are used for manufacture of prepreg components in the aerospace, automotive and other industrial sectors. HexTool® has a similarly low thermal expansion and is almost six times lighter than the high-quality tool steel INVAR. When making the mould, a rough contour model is sufficient. After curing in an autoclave, the mould cavity is milled to its final dimensions using CNC machining. Unlike conventional composite moulds, HexTool® moulds can be repaired or modified at any time. HexTool® consists of carbon fibre and BMI resin (HexTool M61) or epoxy resin (HexTool M81) and is vacuum-tight, pressure-resistant and temperature-stable when cured.
