Impossible Objects, LLC of Chicago has developed a novel 3D composites additive manufacturing technology known as Composite Based Additive Manufacturing (CBAM) to produce Carbon Fiber Reinforced Plastic (CFRP) and/or Polymer Matrix Composite (PMC) parts from carbon fiber, Kevlar and glass fiber nonwoven materials. This will include an overview of thermoplastic composites that explains when enough heat is added to the thermoplastic above its melt point allowing for flow and attachment to the fibers within the nonwoven composite sheet. Thermoplastic composites offer lighter weight part options and have good impact resistance and damage tolerance.
Whereas, thermoset composites are liquid resins flow into the fibers, cured into a solid form and cannot be returned to their original uncured form. Composites made with thermoset matrices are strong, have good fatigue strength and are cured into a solid form.
The presentation will explain how the 3D build process works fuses the nonwoven composite together with thermoplastic matrix material, examine material properties of some of current thermoplastic matrix materials, gradient material build capabilities and discuss some of the first application use cases.
- Key take-away will be insights into new material and process development in composites part manufacturing
- Define a wide range of composite material combinations and benefits
- Provide a list of composite applications
