M4-A E-fiberglass Combo Mats are a commonly used form of composite reinforcement composed of woven roving and chopped roving stitch-bonded into one fabric. This construction takes advantage of the bi-directional (0°/90°) reinforcement of woven roving plus the isotropic (360°) reinforcement of chopped glass fiber to provide excellent wet-out and conformability. Their many excellent characteristics have been used to provide superior performance in a broad range of end-use markets such as marine, transportation, recreation, construction, consumer and anti-corrosion.

M4-A Combo Mats are designed to be compatible in unsaturated polyester resin systems. They offer excellent stiffness and impact resistance for cost-sensitive structural laminates. By combining woven roving and chopped fiber, lay-up reduced, leading to savings in labor and time, wet-through, and resin usage are material costs.

Stitch-bonding a binderless mat allows the fabric to maintain physical integrity when saturated with resin, yet still retaining the conformability required for fast laminate build-up. To help ensure the quality of customers’ products, the quality management programs of manufacturing M4-A Combo mats are controlled under the requirements of ISO 9001.

Packaging

M4-A Combo Mat is wound into a roll on a cardboard inner tube with an inside diameter of 7.2cm (2.8"). All densities are 24cm (10") in diameter. Each roll is wrapped with a plastic bag and placed in a cardboard box. 12 or 16 boxes are placed horizontally on a pallet, which is stretch wrapped.

Storage

Unless otherwise specified, it is recommended to store glass fiber products in a cool, dry area.

Temperature should not exceed 35°C (95°F) and the relative humidity should be kept below 75%. Fiberglass products must remain in packaging material until just prior to its use. If these conditions are respected, the glass fiber product should not undergo significant changes when stored for extended periods of time.

Stacking

To ensure safety and avoid damage to the product, skids should not be stacked.
