Combi Mats

Combination mats made of woven roving and chopped strand mat for composite processing

Combination mats combine the positive properties of woven roving and chopped strand mat in a single reinforcing material for composite processing. They consist of roving layers (0°/90°) combined with a chopped strand mat (CSM), which are firmly stitched together. This structure provides high tensile strength, flexural strength and an isotropic reinforcing effect, making the production of laminates significantly more efficient. In the HP-Textiles online shop, the combination mat HP-PC1050AD is available – either as a complete roll of 50 kg (46 m²) or in pre-cut small quantities for smaller composite projects, repairs or prototype construction.
 

What makes the combination mat particularly suitable for composites?

The combination mat HP-PC1050AD is made of Advantex® ECR glass and impresses with its high corrosion resistance and long service life. With an area weight of 1050 g/m² and a width of 125 cm, it provides the necessary stability for robust laminate constructions. The interaction of woven roving and chopped strand mat ensures optimal resin absorption and wet-out – whether with epoxy resin, polyester resin or vinyl ester resin. At the same time, the combination mat reduces processing effort, as several reinforcement properties are combined in just one step. The result is stable, uniform and durable laminate structures with high chemical resistance.
 

Which variants of the combination mat are available?

In the HP-Textiles shop, two variants of the HP-PC1050AD combination mat are available: complete rolls of 50 kg (46 m²) for industrial series production and large consumers, as well as pre-cut small quantities, which are perfect for repair work, prototype construction or smaller laminating projects. This means that both industrial customers with high material requirements and craftsmen, model builders and boat builders who need smaller quantities benefit from the same high quality and reliability.
 

For which applications is the combination mat suitable?

The combination mat is used in numerous composite applications – from boat building to vehicle construction, body construction, mold making and pipeline construction. Thanks to the combination of woven roving and chopped strand mat, it is ideal for laminating processes that require uniform resin distribution, high dimensional stability and excellent mechanical properties. Especially in large laminate constructions, in industrial series production or in environments with high chemical exposure, it plays to its strengths. This makes the HP-PC1050AD combination mat an indispensable reinforcing material for modern fiber composite technology.
