Invention Reference Number
This invention utilizes a dual function splice to enhance splice strength for opposing fiber tows, addressing inconsistencies in the splicing process common in the continuous fiber processing industry.
Description
This invention addresses the challenges of serial splicing in the continuous fiber processing industry, such as pultrusion, where current methods yield inconsistent results dependent on individual skill. A solution is needed to create stronger splices without compromising infusion performance. This invention involves a dual splice process that first entangles the fibers, followed by a wrap to enhance friction between the fibers. This innovative approach significantly increases splice strength while maintaining infusion efficiency, leading to improved final properties in the processed composites.
Benefits
- Improved joining technique: Combines the advantages of entanglement and wrap splicing into a single method.
- Enhanced strength and consistency: Achieves stronger and more consistent fiber tow joining compared to current methods.
- Reduced variability: Minimizes issues related to operator dependency, ensuring more reliable results.
- Superior alternative: Offers a more effective solution than commingle splicing, wrap splicing, and knot tying.
Applications and Industries
- Continuous fiber composite manufacturing processes: Pultrusion, filament winding, and continuous fiber printing
