Ekoa is a fiber reinforced pre-impregnated natural composite materials with high performance and low environmental impact. Lingrove® Pre-preg resin systems are manufactured with post-industrial biobased resins and are available in a high temperature cure (250°F, 120°C) pre-preg resin system. These resins exhibit excellent mechanical properties and improved impact resistance over conventional epoxy pre-preg systems. Lower temp cure resins are also available.
Typical fiber weight ratio: 50% (+/- 3%)
Recommended cure cycles
For best results a heat ramp of 1-2°/min with a dwell at 180°F (80°C) for 30 min and an
additional dwell at the minimum activation temperature for 30 min is recommended.
Process via standard composite manufacturing techniques including: compression molding, RTM, VARTM, and wet layup.
The material should be kept frozen at -18°C. It must be kept in sealed plastic bags which must
not be opened until fully thawed to room temperature. Shelf life at -18°C is no less than 12 months.
Health and Safety
Despite their natural derivation, exposure to these materials represents hazards typical to all
epoxy resins. Exposure should be minimized and avoided through the use of proper protective
clothing and equipment and appropriate manufacturing controls. All persons who use, store, or
transport these materials should properly understand the handling precautions and
recommendations as stated in the MSDS. Please refer to the MSDS for the most up to date
Safety and Handling information.
Near-zero CTE, hence good processing compatibility with carbon fibers.
Suitable for: Vacuum molding, autoclave molding, bladder mo lding (BIM), compression molding.
