Biaxial Cloth & Tape
Biaxial fabric is a non-woven which consisting of 2 layers stitched together at +/- 45 deg. which drapes nicely, and is used in structural work as it gives strength in 2 directions. Biaxial fabrics are easily cut using standard shears and are easily handled. Compatible with Epoxy, Vinylester and Polyester Resins to reinforce boat hulls, panels and are used in general composite GRP mouldings.

Biaxial cloth is a type of reinforcement material used in composites, particularly in the production of fiberglass-reinforced plastics (FRP), (GRP) or composites as its now more commonly known. It is a fabric made from woven fiberglass fibres, and "biaxial" refers to the orientation of the fibres in two directions either +- 45 degrees or 0 – 90 degrees.
Here are some of the key characteristics and features of fibreglass biaxial cloth:
1. Bi-directional Reinforcement: Biaxial cloth is woven with fibres oriented in two directions, typically at 0 and 90 degrees or + - 45 degrees. Thus providing strength along both the length and width of the fabric, enhancing the overall mechanical properties of the composite material.
2. High Strength-to-Weight Ratio: Fiberglass is known for its high strength-to-weight ratio, making it a popular choice for reinforcing materials. Biaxial cloth further optimizes the distribution of strength in multiple directions.
3. Conformability: These fabrics are designed to conform easily to complex shapes and making it suitable for a variety of applications where shaping and moulding are necessary.
4. Resin compatibility: A Biaxial cloth is used in conjunction with a number of various resin systems such as polyester, Vinlylester, and Epoxy resins. The resin matrix binds with the fibres, creating a durable and strong composite material.
5. Applications: Typical applications of fiberglass biaxial cloth include boat/yacht building, automotive parts, aerospace parts, wind turbine blades, leisure sports equipment, and other structures where a combination of strength and lightweight properties is beneficial.
6. Processes: It can be used in both hand lay-up and vacuum infusion processes, providing much flexibility in production methods.
7. Available weights: A Biaxial cloth is available in different weight and thickness options, ranging from 300g – 450g- 600g and typically 800g per mt2, allowing manufacturers to choose the most suitable material for their application.
