Technical Fibre Products will be featuring its advanced nonwoven solutions at the China Composites Expo, to be held at SWEECC in Shanghai from 5-7 September. This year, the focus will be on how TFP’s Optiveil nonwovens deliver a quality surface finish, with examples from the sporting goods industry displayed.

Optiveil nonwovens are designed to provide an effective surface finish solution for composites; with proven results in applications from the aerospace, automotive, sporting goods, marine, energy and industrial sectors, the company explains.

The majority of uses for Optiveil are proprietary, but this year at China Composites Expo TFP will exhibit some new examples of their veil in action. These parts include a composite bicycle frame, which demonstrates how Optiveil provides both a superior surface finish and a means of improving resin flow in the structure. This dual function is characteristic of TFP’s nonwovens, which can offer a range of benefits simultaneously; including fracture toughness, EMI shielding, electrical conductivity, galvanic corrosion prevention, and corrosion and abrasion resistance.

“Optiveil is the ideal candidate for use as a surfacing veil, producing a high-quality resin rich surface finish with micro crack suppression and minimum microporosity. It is available in range of fibre types to enable both a variety of aesthetic finishes and CTE matching and boasts an exceptionally even fibre distribution to ensure uniform resin uptake,” the company says.

“In addition, the porous structure of the veil provides the benefit of enhanced resin flow, aiding resin distribution in the part without the need for additional flow media. Ultimately, this can eliminate the need for additional flow media and help to optimise composite production times and yields.”

“Surface finish is only one of many solutions our nonwovens can provide for composites.”
