Aluula introduces lightweight composite materials for wind sports and beyond



Advanced materials technology firm Aluula Composites Inc. (Victoria, British Columbia, Canada) introduces a range of ultra-strong lightweight fabrics that combine with polymer films in a patented fusion process to increase performance in windsports and other applications.

Founded in 2019, Aluula is the brainchild of chemists and engineers with a passion for outdoor sports. The initial objective was to engineer materials that would better serve kiteboarding and the quickly growing wing foiling market. Both markets had inherited legacy materials and seaming techniques from the sail industry, and technical and material developments had stalled. However, surging interest in these wind sports started driving innovation and development of new materials. The Aluula Composites team set out to develop materials with kiteboarding weight, strength and performance objectives in mind, as well as toughness and ability to withstand harsh sun and abrasive beach environments.

The resulting product line, according to Aluula, is a new class of composite materials built from components with eight times the strength-to-weight ratio of steel, and yet are lighter than nylon, polyester or aramid. Aluula’s technology combines one of several Aluula Core fabrics with one of the company’s technical films, via its patented Aluula Fuse process. 

Aluula Cores are said to be proprietary formulations of 100% ultra-high molecular weight polyethylene (UHMWPE). These include Aluula Gold GC-82, an 82-gsm fabric used within wind sports for lightweight, rigid airframe structures, and ultra-durable, lightweight Aluula Durlyte HH-140 for reinforcing airframe seaming.

Aluula Fuse is a fusion process for binding high-tech fabrics and technical films together without the use of heavy glues. This process is said to result in a stronger, lighter material that will not delaminate and is less susceptible to UV and general abuse. Fusing materials without glues in this way is also said to make the fabrics recyclable at their end of life (EOL).

Alongside developing new fabrics and films to suit different needs, the company also says it can develop customized materials for unique applications.

Revolutionizing Concrete with Recycled Plastic Fibers The integration of woven recycled plastic fibers in reinforced concrete is transforming the construction industry by enhancing durability, reducing environmental impact, and promoting sustainability. These fibers improve tensile strength, crack resistance, and flexibility while significantly lowering reliance on conventional steel reinforcement. By repurposing plastic waste, this innovation contributes to a circular economy and reduces landfill pollution. The method aligns with green building practices, offering a cost-effective and eco-friendly alternative for modern infrastructure. As industries move toward sustainable solutions, recycled plastic fiber-reinforced concrete is gaining traction as a game-changer in construction.

PRF Composite Materials introduces RP570 FR eXpress cure prepreg system

  PRF Composite Materials introduces RP570 FR eXpress cure prepreg system Composite Matedrials  (Poole, Dorset, U.K.) presents its RP570 FR eXpress cure prepreg system. Formulated for structural components requiring fire, smoke and toxicity (FST) properties, RP570 FR is a fire-retardant, ultra-fast prepreg system which is cured and demoldable after five minutes at 160°C. According to the company, the express resin system is primarily designed for snap cure press molding. However, it can equally be used in conventional autoclave molding and reduce time in the autoclave — up to 50% less — thus increasing productivity and lowering energy consumption per part. RP570 FR is tested to Federal Aviation Requirements 25.853 Appendix F Part 1, AITM 2.0007 and 3.0005, UL94 V1 and FMVS Standard No.302. “RP570 FR is part of PRF’s drive to develop materials that offer measurable advantages in cost reduction and improved sustainability,” Dave Ellson, managing director, PRF Comp...

Aluminium-based metal matrix composites step into the middle ground

Image
Alvant undertakes high-precision CNC machining Comparison of AMC properties vs four relevant metals and compostie materials Advanced composite materials combine the properties of high strength, high stiffness, low weight, enhanced damage tolerance and corrosion resistance – and in some cases also have special thermal and electrical properties. These composites are classified according to the material being reinforced, with reinforcements typically made with a long fibre, short fibre, or particulates. Hence metal matrix composites (MMCs) are metallic materials reinforced with a secondary high-performance material. Within the category of MMCs, Alvant specialises in aluminium matrix composites (AMCs). AMCs first became known, primarily for their use in automotive components, in the 1980s. At this time AMCs were in their infancy, their properties largely unproven and sometimes over-sold. As a consequence, their reputation suffered, and as carbon composites became more widely adopted, AMCs...
