Description:
Fiberglass mat is a non-woven reinforcing material composed of randomly oriented glass fibers bonded together with a resin-soluble binder. This open structure allows for excellent resin absorption, making it ideal for building thickness and enhancing interlayer adhesion in composite laminates.
Key Features & Benefits:
-
Versatile Layering: Works synergistically with fiberglass cloth or roving to improve bond strength between layers and add bulk to laminates.
-
Conformability: Easily molds to complex shapes and compound curves when saturated with resin, making it perfect for contoured surfaces.
-
Cost-Effective: Provides rapid thickness buildup at a lower cost compared to woven fabrics.
-
Resin Compatibility: Designed for use with polyester resin (binder dissolves optimally in styrene), though epoxy-compatible mats are available for specialized applications.
Applications:
-
Hulls, decks, and automotive body repairs
-
Mold making and plug construction
-
Repairing irregular surfaces or curved structures
-
Core bonding and filler layers in multi-layer laminates
Limitations:
-
Lower strength-to-weight ratio compared to woven cloth or roving of equal weight.
-
Not suitable for high-stress structural applications without reinforcement.
Recommended Tools:
-
Mat Roller: Essential for removing air bubbles and ensuring proper resin saturation, improving both appearance and mechanical properties.
Available Weights:
Fiberglass mat is categorized by weight per square foot (unlike cloth/roving, which uses square yards):
-
3/4 oz/sq ft: Lightweight, for fine surface work.
-
1-1/2 oz/sq ft: General-purpose reinforcement.
-
2 oz/sq ft: Heavy-duty buildup and repairs.
Pro Tips:
-
For epoxy systems, use “stitched” or “powder-bound” mats labeled as epoxy-compatible.
-
Always wear gloves and PPE—loose glass fibers can irritate skin.
-
Pre-cut mat to size before resin application to minimize handling.
