SOLUTIONS FOR PULTRUSION

Product catalog summary
Introduction to Volumat™
Volumat™ is a reinforcement material composed of fabric or multiaxial mat, mechanically bonded through the needleloom process without chemical binding.

Advantages
  • The needleloom process increases the volume of reinforcements, allowing for greater part thickness.
  • Ideal for parts with sharp angles due to high volume fibers that fill critical areas optimally.
  • Incorporates a fabric or multiaxial backing, enhancing transverse mechanical strength.
  • Does not fray during processing, resulting in a superior surface finish compared to other reinforcements like CFM.

Applications
Volumat™ is recommended for manufacturing parts requiring enhanced mechanical properties, particularly in the pultrusion process.

Complementary Solutions
The Volumat™ range addresses specific design and manufacturing constraints in pultrusion. Chomarat offers additional reinforcement materials with complementary characteristics.
  • Volumat™ is a layered reinforcement, mechanically bonded, providing stability and strength similar to G-ply™.
  • Can be composed of glass, aramid, carbon, or a combination of fibers.

Related Products
  • FIXed DiaGonap™: A fixed bias-woven reinforcement with angles between 30° and 60°, optimizing reinforcement orientation for improved flexural and torsional strength.
  • DiaGotex™: A "non Crimp Fabric" made of unidirectional layers, providing stability and mechanical performance in pultrusion, with triaxial fibers enhancing torsional strength.

SOLUTIONS FOR PULTRUSION-1

Pultrusion enables continuous produc- tion of straight composite parts with complex sections, hollow profiles or sharp angles. This process means you can achieve very high reinforcement levels (60 - 70%) with high strength.

VOLUMAT™ is a combination of fabric or multiaxial + mat, mechanically bonded by the needleloom process, without chemical binding. • This needleloom process adds volume to reinforce- ments which means greater part thicknesses can be • It is highly advantageous for parts with sharp angles, because high volume fibers allow optimum filling of critical areas. • The use of a fabric or multiaxial backing for VOLUMAT™ adds transverse mechanical strength to finished products. • Does not fray during processing which gives a better surface aspect than most of other reinforcements like facture of parts that...

SOLUTIONS FOR PULTRUSION-3

COMPLEMENTARY SOLUTIONS The VOLUMAT™ range was specifically designed to deal with certain design and manufacturing constraints involved in the pultrusion process. However, CHOMARAT does offer other reinforcement materials which can be used in this process and offers complementary characteristics. Assembly of a 300 g/m2 fabric to a specific "long-fiber" APPLICATIONS ADVANTAGES This reinforcement material is particularly suited to the production of wide parts which need a high level of mechanical characteristics. The long-fiber mat facilitates holding and forming before it goes into the die and...
