Fiberglass & reinforcing materials for Acrylic Resin (A1)
Reinforce your acrylic resin applications with professional-grade fiberglass and reinforcement products . Ideal for support caps, thin sections, and structural projects. Combine these materials with A1 acrylic resin for maximum strength, dimensional stability, and durability.
Key benefits
- ✓ Strong structural reinforcement for A1 acrylic resin and composites
- ✓ Light but stiff constructions with fiberglass cloth or twill weave
- ✓ Smooth finish with C-veil glass fiber
- ✓ Simple local reinforcement with chopped fibres
- ✓ Compatible with acrylic resin, epoxy, polyester and silicone
Applications
Support caps and molds
Combine A1 triaxial fiberglass cloth or woven cloth with acrylic resin to create strong, lightweight support caps for silicone or alginate molds.
Structural reinforcement
Reinforce thin sections or large surfaces with twill weave or reinforcement cloth for increased stiffness without adding weight.
Repairs and prototypes
Use chopped fiberglass as a filler for small repairs, model modifications, or industrial prototypes.
Processing and tips
- → Mixing: Use standard A1 acrylic resin (powder + liquid) and add reinforcement material in the wet phase.
- → Laminating: Lay the canvas in layers, saturate it with acrylic resin, and press out air bubbles with a roller or spatula.
- → Finish: Apply a layer of C-veil on top for a smooth surface.
- → Reinforcement: Add chopped fiberglass (0.5–5%) to reinforce sections or combine fillers.
- → Safety: Wear gloves, dust mask and work in ventilation when cutting or mixing fibers.
Compatibility and considerations
A1 Acrylic Resin
All reinforcement materials mentioned are fully compatible.
Epoxy and Polyester
Fiber optic also works with these systems, but adjust the mixing ratio and processing speed.
Silicone
Chopped fibers can be added for extra tear resistance, but limit elasticity.
Temperature
Avoid processing below 10 °C for optimal adhesion and curing.
Always check the product TDS for exact instructions and processing parameters.
Product overview
A1 Triaxial Fiberglass Cloth
- Consists of three layers of fibers at 45° for multidirectional strength
- Light and stiff, ideal for support caps and structural applications
- No woven structure, therefore flexible in processing
C-veil Glass fiber 30 g/m²
- Fine glass fiber for a smooth finish after lamination
- To be used as a top layer over triaxial cloth
- Improves surface quality and paint adhesion
Woven glass fiber cloth 200 g/m²
- Thinner and more flexible than triaxial fabric, drapes better around shapes
- Suitable for smooth surfaces and complex contours.
- For durable, lightweight laminates in acrylic resin and epoxy
Glass fiber twill weave 200 g/m²
- Twill weave drapes better than flat woven fabric
- Provides a smooth finish on curves and bends
- Slightly less stiff, but excellent to combine with triaxial layers
Cut Fiberglass 6 mm
- Short-cut fiber for local reinforcement and filler
- Suitable for acrylic resin, epoxy, PU, polyester and silicone.
- Budget-friendly, easy to dose
Cut Fiberglass 12 mm
- Long fibers for extra structural strength
- Can be mixed well with acrylic resin and other resins
- Increases stiffness and impact resistance of castings
Frequently Asked Questions
What is the difference between triaxial and woven fiberglass cloth?
Triaxial fabric has fibers in three directions (0°/±45°) and provides greater structural strength, while woven fabric is more flexible and better suited for complex shapes.
Can I combine fiberglass with A1 acrylic resin?
Yes, all fiberglass products are A1 compatible. Use layers of cloth or add chopped fiber to the wet mix for extra stiffness.
What do I use C-veil for?
C-veil is used as a finishing coat for a smooth surface. It contributes little to strength but improves aesthetics and coating adhesion.
How much chopped fiberglass can I add?
Typically 0.5 to 5% of the total weight. Start with a small amount and adjust to the desired viscosity and strength.
Can I also use these products with epoxy or polyester?
Yes, fiberglass and non-woven fabrics are also suitable for epoxy and polyester, but adjust the curing time and mixing ratio according to the system used.
Advice and orders
Choose the right fiberglass or reinforcement type for your project: triaxial fabric for maximum strength, C-veil for a smooth surface, or chopped fiberglass for localized reinforcement. Combine with A1 acrylic resin for professional results. Questions about the right choice? We're happy to help.
