Lightweight high performance fabric for sporting goods and decorative applications 200g/m²
Biotex Flax provides high levels of performance, coupled with the ease of processing normally associated with glass-reinforced materials. The materials use low-twist technology to provide a combination of sustainability, performance and processability not previously seen in composites. Compared to glass fibre composites, Biotex Flax offers reduced weight, improved environmental impact, vibration damping, similar specific stiffness and safer handling.
Biotex Flax is available in a range of yarn weights and fabric constructions. The materials can be processed using standard composites manufacturing techniques and are suitable for semi-structural and decorative applications in a range of sectors, including automotive, sports & leisure, consumer goods and construction.
Biotex Flax 200g/m² 2×2 Twill fabric is typically used for lightweight and decorative applications in sporting goods, consumer goods and automotive interiors.
Specification
- Weave Style: 2x2 Twill
- Fabric Weight: 200 g/m²
- Width: 1500 mm - others on request
- Typical Ply Thickness: 0.25-0.4 mm, depending on process
Processing
Typical processes for Biotex Flax fabrics include vacuum infusion or resin transfer moulding using either standard resins or bio-based resins. The fabrics can also be pre-pregged, and processing is carried out in the same way as glass fibre.

Data from vacuum infused laminates using unsaturated polyester resin, tested at ambient temperature.
Safety
Biotex Flax reinforcements are based on renewable biomass and have fewer health and safety concerns than many conventional alternative materials. However, typical precautions should be taken when handling the material including using appropriate PPE and adequate ventilation.
Case Study:

Environmentally-Friendly Surfboard
Background
Australian surfboard manufacturer Samsara Surf prides itself on pushing boundaries, delivering high-performance surfboards which are also eco- friendly. All of its surfboards are handmade or precision-machined at their shop in Victoria.
Currently, carbon fibre is the industry-standard reinforcement for stringerless surfboards. Jason Wiggers, Owner of Samsara Surf, was aware that the surf community are environmentally conscious. Passionate about the environment himself, he wanted to find an alternative to carbon fibre for his next project to make eco-friendly boards more easily available to the community.
Carbon Fiber Australia introduced Wiggers to Composites Evolution’s sustainable, high performance reinforcement materials. Impressed by technical data sheets for Biotex, Wiggers decided to make a prototype stringerless board using Biotex Flax.
Biotex Flax gave Samsara Surf the high-performance results it needed, helping it to stay true to its vision of providing eco-friendly surfboards.
Why Biotex Flax?
Composites Evolution suggested that Samsara Surf use Biotex Flax as it has excellent damping properties whilst still remaining lightweight.
Material Selection
Performance: Biotex Flax can be used in the same way as carbon fibre or fibreglass, meaning that once supplied Samsara could construct the eco-surfboard without having to change their existing process. Once constructed the board was tested extensively with excellent results.
