OPTIVEIL® Carbon Fibre Tape 20gsm – 180mm wide

Optiveil® is a highly porous nonwoven veil which is produced from short chopped engineered fibres. These materials have been specifically developed for use in advanced composite structures and are used in a variety of industries worldwide, including aerospace, defence, automotive, construction, industrial, consumer electronics and energy.

The key benefits of Optiveil® nonwovens include; excellent resin uptake, tuneable properties and exceptionally even fibre distribution. This makes Optiveil® the ideal candidate for providing a high quality surface finish and effective surface engineering of composites, as well as aiding fabrication through acting as a lightweight support or carrier.

MATERIAL USE
Optiveil® is compatible with all common resin systems and fabrication techniques. The broad choice of nonwovens offered can enable composite compatibility via matching of the fibre coefficient of thermal expansion (CTE) with that of the underlying reinforcement, whilst polymer binder can be selected to suit the resin system in use and meet processing requirements.

Fibre reinforced composites, comprising of a layup of carbon reinforcement fabrics infused with epoxy resin, can exhibit low interlaminar fracture toughness. In service these composite materials can be prone to interlaminar failure under both Mode-I and Mode-II loadings. The presence of interlaminar damage can be very detrimental to the composite delamination fatigue properties and ultimately compromise the mechanical performance of the structure. Recent studies indicate that the use of TFP’s thermoplastic veils can engineer a significant improvement in the Mode-I and particularly Mode-II fracture toughness, for the latter an improvement of up to 350% & 430% (for initiation & propagation respectively) can be achieved.
