Product Description
Direct Roving For Filament Winding
Direct Roving for Filament winding, is compatible with unsaturated polyester, polyurethane, vinyl ester, epoxy and phenolic resins.
Filament Winding Process
Traditional Filament Winding
In the filament winding process , continuous strands of resin-impregnated glassfiber are wound under tension onto a mandrel in precise geometric patterns tobuild up the part which is then cured to form the finished parts.
Continuous Filament Winding
Multiple laminate layers , composed of resin , reinforcement glass and other materials are applied to a rotating mandrel , which is formed from a continuous steel band continuously traveling in a cork-screw motion . The composite part is heated and cured in place as the mandrel travels through the line and then cut into a specific length with a traveling cut-off saw .
Product Feature
- Good process performance and low fuzz
- Compatibillty with multiple of resin systems
- Good mechanical properties
- Complete and fast wet-out

Packaging & Shipping
Storage
Unless otherwise specified, fiberglass products should be stored in a dry, cool and rain-proof area. It is recommended that the room temperature and humidity should be always maintained at 15ºC~35ºC and 35%~65% respectively. To ensure safety and avoid damage to the product, the pallets should not be stacked more than three layers high. When the pallets are stacked in 2 or 3 layers, care should be taken to correctly and smoothly move the top pallet.
The product should be transferred to the workshop 24 hours before use to undergo conditioning.
Packaging
The product can be packed on pallet or in small cardboard boxes.
