Henkel’s aerospace group has launched Epsilon 99100, a benzoxazine RTM/VARTM resin system, optimized for aerospace applications.
Henkel say that this innovative technology is an efficient and effective alternative to the epoxy chemistry. Epsilon 99100 significantly enhances mechanical performance and durability, while lowering the costs associated with composite structure during manufacture and service.
Epsilon 99100 represents the first of a family of aerospace composite resin systems which will be introduced in 2008. Epsilon 99100 is stable at ambient temperatures for over a year as a one-part resin and , according to Henkel, features include:
• Broad processing window – great for large parts and intricate shapes
• Viscosity stability – long injection window for large parts
• Low heat release during cure – allow for manufacture of large parts, lowers residual stresses
• Low cure shrinkage – improved translation of strength in final part
• Fire retardant – suitable for aircraft fuselage and interior applications
• High hot/wet property retention – higher service temperature to enable a wide range of aircraft applications
• Improved UV resistance – no discoloration compared to epoxies
• Good thermal resistance – acceptable for high temperature areas
Additionally, this 180°C cure resin system provides a combination of properties including hot/wet glass transition temperature at 165°C, high toughness, high compressive strength and modulus, good solvent resistance and FST properties.The Epsilon benzoxazine family of resins has a unique orange colour.
“Epsilon 99100’s wide range of applications will revolutionize aircraft composite assemblies as a result of its unique combination of benefits as a structural composite resin”, said Raymond Wong, vice president of technology, Henkel. “This innovation is a result of Henkel’s commitment to developing new and innovative cost-effective technologies for our customers.“
New at Advanced Engineering 2018 will be the Rösler 'plug and play' RMO trough machine, a compact, mobile and versatile system for finishing both plastic and metal parts, including AM/3D printed.
R-Tech Materials has achieved Nadcap accreditation for the testing of non-metallic materials for the aerospace industry. The scope of accreditation covers a range of mechanical tests on composite materials, and opens the way for R-Tech to offer its testing services to the aerospace sector.
At Advanced Engineering 2018, MSA Manufacturing is promoting its extensive CNC cutting, slitting, 2D preforming and sequenced kitting capabilities for a wide range of glass and carbon fabrics, along with 3- and 5-axis CNC machining and kitting of cores for manufacturing composite parts.
