and spar wing reinforcement

9 oz/sq yd weight allows multiple layers while maintaining reasonable laminate thickness for complex layup schedules

Minimal polyester fill threads on one side further reduce crimp potential

Thixotropic Silica Options:Carton (7 lbs) Kevlar or most fiberglass fabricsA white, free flowing powder, Thixotropic Silica is a thickening agent primarily added to resin to prevent run off and sags on vertical surfaces. Use with an epoxy to produce extremely hard, solid parts, perfect for structural bonding, filling, and filleting. Use in conjunction with chopped glass fiber for added strength for parts. Silica filled resin can be difficult to sand. Consider using #22 Glass Microspheres for areas that require sanding. This
