Open and closed molding processes are used to manufacture epoxy matrix composite parts/components. Master Bond thermoset epoxy systems feature high tension, compression, shear, flexural strength, resist corrosion, abrasion and have superior thermal properties. Glass, aramid, carbon, boron reinforced long/short fibers, particulates, discontinuous/continuous fibers such as woven, unidirectional, knitted fabrics are impregnated with low viscosity epoxies to bond/protect advanced composites against delamination, impact, high temperature creep, osmosis, fatigue, chemical attack, micro-cracking. Type of fiber, orientation, geometry, spacing, properties of epoxy, curing/post curing procedures are essential to the fabrication of structures offering:
- light weight
- stiffness
- high strength to weight ratio
- dimensional stability
- durability
- design flexibility
- reduced labor cost
- serviceability at high/low temperatures
- non-magnetic
- electrical insulation
- complex shapes
- decreased number of parts
Low temperature curing, solvent free two component epoxy systems have a long pot life at ambient temperatures and are engineered to shorten cycle times. These low shrinkage formulations withstand degradation from water penetration and maintain their mechanical properties after aging.
Epoxy matrix composites are frequently employed for interior/exterior aircraft applications including wing assemblies, radomes, instrument enclosures, landing gear doors. They improve energy efficiency, increase payloads/range for commercial/business jets, military tanks, wind turbine blades, generators, pumps, switchgear, dishwasher appliances, sports equipment, automotive components and replacing metals in machine tools. Additionally they minimize corrosion in infrastructure building projects and marine environments.
