Carbon spring technology is up to 70% lighter than steel
Abssac is constantly working on next generation product platforms and a classic example of this is the carbon spring technology from Hyperco. The carbon spring works as a system to offer unparallelled control of your spring set-up, as well as saving you up to 70% of the weight of a steel spring.
A carbon spring stack stores energy by bending. This bending action replaces the friction generating tilt of a coil spring. Delivering squareness under load, the Carbon Spring technology saves you unavoidable side load and reduces overall friction associated with coil springs.
In applications where it’s all about weight, you can massive reduce the weight of your current system, shedding almost three quarters of the weight of a steel spring while improving the dynamic response with its reduced mass.
The carbon spring technology gives you the flexibility to adjust your spring rate in any increment. The great thing, says Abssac, about building a single spring from many small elements is the ability to alter just one element and affect a very small change on the assembly. Or, you can swap out many components and see a large change. In this way, a carbon spring stack can be tuned in very small or large increments.
Abssac says this tune-ability of rate, along with free length and displacement offers unprecedented flexibility in making spring rate decisions.
Titanium springs often have a high cost per rate. Utilising a stock of carbon spring elements from which to build your required stack and rates, Hyperco carbon spring technology can save you money.
In practical usage, the Carbon Composite Bellows spring (CCBS) is a system of carbon fibre elements that combine to work as a high performance, light weight and design flexible compression spring. Meant to replace conventional coil springs or metallic Belleville disc springs by offering value through unique dynamic characteristics and unparalleled in-the-field design flexibility, the CCBS offers new solutions to old challenges.
A functional spring is made from several individual elements, paired in sets and joined to make a stack. The spring rate of the stack is determined by the number of elements, the base rate of each element, and their series or parallel orientation in the stack.
The manufacture of carbon fibre parts is through moulding. This allows for complicated and intricate designs to be formed in a single operation and permits design features not possible with a machined or stamped metallic part.
Laminate construction permits steeper pitch angles to allow more deflection per element without overstressing.
