AOC introduces new line of resins
TECHNOLOGY Scott & Fyfe adds flame retardant glass mat
Lach Diamant expands tool range for fibre reinforced materials
SCOTT & FYFE has introduced Polymat FR, an extensive chopped glass mat designed for RTM applications, as a new addition to its Polymat range. Scott & Fyfe says that the product will be targeted at applications requiring the highest level of fire performance, such as rail interior parts that must comply with standards such as EN 45545.
by weight glass ratio, allowing for high strength laminates. The company adds that the product is also designed to offer fast and efficient resin flow, improving reliability of production when used with highly filled resins.
LACH DIAMANT is expanding its diamond tool programme for the processing of fibre reinforced materials such as carbon fibre reinforced plastics, glass fibre reinforced plastics and mixed materials.
Paul McMullan, Business Manager, said: “Early response from the market has been very positive and we are excited about the position this product will take within the fire performance composites segment.”
The Lach Diamant Tools can be used for machining, turning, drilling, milling, cut-off and deburring of fibre reinforced materials. For the last 40 years this programme has been available for applications in the aircraft and wind power industries, as well as for the leading processors in the plastic industry. The company adds that it is now available for PCD and electro-plated tool applications.
The product is comprised of a 100% glass core, which is sandwiched between two layers of chopped strand mat. Typically, laminates will achieve up to 40%

Composite solution for aircraft fuel systems developed
A new lightweight composite solution for aircraft fuel systems has been developed by Technical Fibre Products Ltd and AGC AeroComposites.
TECHNICAL FIBRE Products Ltd (TFP) and AGC AeroComposites (AGC) have introduced a new lightweight composite solution for aircraft fuel systems. The companies add that that this joint development, patent pending, enables the electrical resistance of composite components to be precisely controlled and has the potential to provide a weight saving of up to 200 kg per aircraft.

TFP and AGC have collaborated in the joint development of electrostatic and lightning compatible composite pipes suitable for use in aircraft fuel systems. The shared technology enables the surface resistivity of the glass-based composite pipe to be precisely controlled, therefore the structure is electrically isolating to resist lightning strike propagation but sufficiently conductive to dissipate the static electricity resulting from fluid movement. The companies say that the development is the first of its kind and presents the opportunity to save weight in aircraft fuel systems by replacing the heavier metallic equivalents Technical Fibre Products Ltd; www.tfpglobal.com AGC AeroComposites; www. agcaerospace.com

AOC introduces new line of resins GLOBAL RESIN supplier AOC has developed a line of resins to meet the increased demand for high-performance carbon reinforced composites in aerospace, automotive, wind energy, military, marine and other markets. The R058 series of epoxy vinyl ester resins is specifically designed for carbon fibre reinforcements and creates lightweight composite parts with good strength-to-weight ratios. AOC says that the R058 series combines the performance of epoxy resins with the processing speed of unsaturated polyester resins. Designed for vacuum infusion and resin transfer moulding (RTM), R058 has good mechanical properties and chemical resistance. Other benefits
include: room temperature cure for laminates as thin as 2mm; low viscosity for shorter mould fill times and complete fibre wet-out; low laminate exotherm for improved surface aesthetics; and good strength, toughness and chemical resistance over a broad range of temperatures. “The R058 series is an excellent choice for applications requiring lightweight and high-performance laminate,” says Mike Dettre, AOC’s Business Manager. “They don’t require post-curing or autoclaving, which makes them faster to process than most pure epoxy resins. And that’s critical for high-volume applications.” AOC; www.AOC-Resins.com
