Towpreg-Based Composite Pressure Vessels for Hydrogen Storage: Materials, Manufacturing, and Sustainability Perspective

Author: [Bruce Zhou]Affiliation: [Jota Machinery Composites Material Prepreg Solution]Corresponding Author: [jotamachinery@gmail.com]Published : December 05 , 2025 Abstract Robotic automated fiber placement (R-AFP) of carbon-fiber towpregs offers a route to high-throughput, repeatable manufacture of aerospace-grade laminates, but process parameters must be tuned to balance consolidation quality, fiber integrity, and interlaminar performance. This study investigates an R-AFP

What Is the Filament Winding Process? Types, Angles, Uses

Where Engineering Meets Insight Stay informed with technical articles, process explanations, and real-world solutions from Jota Machinery. Let’s Talk Filament winding is an automated composite process that wraps continuous fibers—glass, carbon, or aramid—around a rotating mandrel to build strong, lightweight cylindrical or spherical parts such as pipes, drive shafts, and pressure vessels. Fibers are kept
