Introduction to HiMax® Multiaxial Reinforcements
HiMax® Multiaxial reinforcements, also known as non-crimp fabrics (NCF), are a cutting-edge solution that allows manufacturers to integrate multiple layers of unidirectional fibers in a single fabric. These reinforcements consist of layers of unidirectional fibers oriented in various axes and are typically stitchbonded together to create a highly versatile fabric. The manufacturing of these fabrics takes place at Hexcel's Leicester facility in the UK, leveraging the expertise acquired from the acquisition of Formax in 2016. By controlling the fiber orientation, these multiaxial reinforcements provide exceptional strength and stiffness in multiple directions. Additionally, the weight distribution in the fabric can be optimized, and various fiber types can be mixed to achieve desired performance characteristics.
Advantages of HiMax® Multiaxial Reinforcements
HiMax® reinforcements offer several advantages over traditional fabric forms. By strategically placing reinforcing fibers in different axes, manufacturers can optimize the performance of the final composite laminate. This process minimizes resin-rich areas, enabling a higher weight fraction and ultimately enhancing the mechanical properties of the laminate. Additionally, the use of non-crimped fibers results in improved tensile and flexural properties in the final product, while reducing print-through - a critical factor in applications such as boat hulls and automotive components. Moreover, the stitchbonded nature of these fabrics makes them easier to cut and handle, facilitating the manufacturing process.
Applications and Benefits of HiMax® Multiaxial Reinforcements
The versatility of HiMax® Multiaxial reinforcements makes them ideal for a wide range of applications across industries such as aerospace, automotive, marine, and industrial manufacturing. The ability to place fibers in various orientations allows for tailored mechanical properties in the finished product, enhancing both structural integrity and performance. Whether it's infusing resin for light-RTM or improving tension and flexion properties through complex lay-ups, these reinforcements offer unmatched versatility and quality. Moreover, the enhanced resin penetration and flow, coupled with superior resin migration characteristics, make HiMax® Multiaxial reinforcements a preferred choice for maximizing infusion rates and ensuring high-quality composite components.
