Carbon materials and materials researched and developed extensively by Boston Materials have solved the performance limitations of traditional two-dimensional composites. This new 3D enhanced preform has enhanced laminar flow and z-axis performance, providing performance and functionality at low switching costs.
Boston Materials offers a material that bridges the performance gap between metal alloys and composites. Its patented carbon supercomposite combines the uniformity and toughness of a metal alloy with the lightweight and rigidity of a carbon fiber composite.
Carbon supercomposites feature a new type of three-dimensional carbon fiber reinforced material capable of producing impact-resistant and durable parts, designed for high stress and high temperature applications. Carbon supercomposite pre-topped hybrid materials are designed for pressure vessel, marine, tool, wind energy and aerospace industry applications.
The prepreg is made of standard carbon fiber fabric reinforced with short carbon fibers arranged vertically. The synthetic carbon fiber layer is impregnated with a thermosetting or thermoplastic binder to obtain an isotropic carbon fiber prepreg.
Most notably, compared with traditional two-dimensional carbon fiber composites, carbon supercomposites have 500% higher z-axis strength and 150% higher interlaminar shear strength, which greatly improves impact performance and eliminates Layer phenomenon.
Boston Materials produces carbon supercomposites in prepreg, thermoplastic tape and pre-consolidated sheet formats.
Carbon Supercomposite ™ from Boston Materials
Raised $ 1.75 million
Boston Materials has announced the development of its patented Carbon Supercomposite, a carbon fiber fabric that is characterized by ground carbon fibers magnetically aligned in the "z" direction to provide unusual Layer composite strength. The company has raised $ 1.75 million in seed funding, led by a clean energy venture fund, and Sabic and the clean energy venture group are also involved.
Boston Materials is working with Sabic to integrate carbon supercomposites with polyetherimide (PEI) and polycarbonate (PC), but the company says the fiber has nothing to do with resin and is not related to any thermoset or thermoplastic Resin matrix compatible. The company says the technology improves toughness and strength and allows for increased electrical and thermal conductivity. Anvesh Gurijala, founder and CEO of Boston Materials, said that carbon supercomposites can increase compressive toughness by 300% and compressive strength by 35% compared to traditional pre-compressed systems.
Although this material has potential in a variety of end markets such as pressure vessels, wind energy, automotive and aerospace, the company initially targeted sporting goods and overmolded applications, and plans to launch its first carbon supercomposite in the summer of 2019 Material products.
Carbon supercomposite properties
Stiffness durability
The addition of Z-axis milling fibers mechanically fixes each layer of the composite material, which greatly improves the interlayer fracture toughness and strength of the composite material. This effectively distributes multiaxial loads throughout the material to improve toughness by 300% and strength by 35% without any damage to stiffness, compared to similar carbon fiber materials without Z-milled fiber reinforcement.
Strengthen security
Components made of carbon supercomposite materials undergo significant deformation before their strength decreases or breaks. This allows end users to register changes in the surface stiffness of composite components before a catastrophic failure.
Unique thermal properties
The design of the carbon supercomposite material improves the thermal conductivity of the Z axis by 300%. This allows the polyacrylonitrile-based carbon fiber composite material to match the conductivity of expensive asphalt-based alternatives.
Fast time to market
The company's application team will quickly integrate carbon supercomposites into the design and production processes established by customers to reduce technical risk and production time. Users can also take advantage of the company's R & D team if they have a unique or sensitive application that requires a specialized solution.
