NREL plant-based epoxy enables recyclable carbon fiber; more cost-effective, lower GHG footprint

Green Car Congress

When curing, molecules in the liquid resin bind with each other and around the woven carbon filaments, hardening into a strong and rigid lattice. However, the thermoset-nature of the cured epoxy makes those superior products difficult to break apart, especially without severely damaging the carbon filaments. —Nicholas Rorrer.

Chalmers team develops structural battery that performs 10x better than previous versions

Green Car Congress

Both the carbon fiber and the aluminum foil contribute to the mechanical properties of the structural battery. cell manufacture, and curing of the SBE. Since the carbon fiber also conducts electrons, the need for copper and silver conductors is also avoided—reducing the weight even further.

How a Dual Curing Adhesive Works

Cars That Think

Master Bond UV22DC80-1 is a nanosilica filled, dual cure epoxy based system. Nanosilica filled epoxy formulations are designed to further improve performance and processing properties. As a dual curing system, UV22DC80-1 cures readily upon exposure to UV light, and will cross link in shadowed out areas when heat is added.

U of I team uses frontal polymerization for rapid energy-efficient manufacturing of polymers; saving 10 orders of magnitude of energy

Green Car Congress

Researchers at the University of Illinois have developed a new polymer-curing process that could reduce the cost, time and energy needed, compared with the current manufacturing process. Such curing generally uses large ovens that scale in size with the component.

Henkel launches 7.0 W/mK liquid gap filler aligned with mass production requirements of automotive electronics and power electronics

Green Car Congress

A silicone-based, two-part liquid gap filling TIM, Bergquist Gap Filler TGF 7000 dispenses quickly at a maximum possible tested speed of 18 grams per second and cures in place at room temperature.

Adhesives Gain Popularity for Wearable Devices

Cars That Think

Product formulations include epoxies, silicones, epoxy-polyurethane hybrids, cyanoacrylates, and UV curing compounds. Because it is flexible and produces a lower exotherm — heat released during the polymerization process — than conventional epoxy systems, EP37-3FLF lessens the stress on sensitive electronic components during cure.
