C. A. Litzler Co. Inc. (Cleveland, Ohio, U.S.) is presenting an entry-level, solution-based vertical prepreg treater for the composites industry. The system is designed for unwinding, dipping, drying and winding of woven fabric under controlled conditions, and uses a smaller oven to provide a cost-effective, entry-level option. According to the company, Litzler ovens feature the company’s “Opti-flow” technology for uniform flow and temperature uniformity, especially side-to-side uniformity.
Litzler says it continues to expand its product line to meet demand for lower-cost prepregs in the automotive and aerospace markets. Other products and expertise include dryer technology, compaction rolls, tow spreading, and controls design and automation.
In addition, the company is presenting its Hot Melt Adhesive Coater Filmer for special composites materials. The horizontal coating line is used to coat paper and fabrics for the composites industry.
System features include:
- Precision knife over roll filmer using the same style 0.0002" (0.005 mm) rollers as Litzler Compaction Rolls and Litzler Metering Rolls.
- Resin is fed from the top of the rolls and forms a dam — the web is fed through the precision knife gap to introduce the resin directly.
- Multiple unwinds, rewinds for scrim, paper and poly are said to make this a highly flexible machine for hot melt adhesives.
Compared to legacy materials like steel, aluminum, iron and titanium, composites are still coming of age, and only just now are being better understood by design and manufacturing engineers. However, composites’ physical properties — combined with unbeatable light weight — make them undeniably attractive.
Yes, advanced forms are in development, but has the technology progressed enough to make the business case?
Oven-cured, vacuum-bagged prepregs show promise in production primary structures.
