Avionics & Aerospace Grade Very Low DK Base Material
TLY-3 laminates are manufactured with very lightweight woven fiberglass and are much more dimensionally stable than chopped fiber reinforced PTFE composites. The woven matrix in the TLY-3 material yields a more mechanically stable laminate that is suitable for high volume manufacturing. The low dissipation factor enables successful deployment for automotive radar applications designed at 77 GHz as well as other antennas in millimeter wave frequencies.
Comparative OEM testing at 77 GHz of lightly reinforced TLY-3 vs. its closest chopped fiber reinforced competitor has shown “drop in”/equivalent insertion losses/dielectric properties. The primary benefit is much higher manufacturing yields. The dielectric constant range is 2.17 to 2.40. For most thicknesses, the dielectric constant can be specified anywhere within this range with a tolerance of +/- 0.02. In the low dielectric constant range, the dissipation factor is approximately 0.0009 at 10 GHz. Typical applications include satellite communications, automotive radar, filters, couplers, avionics and phased array antennas.
TLY-3FF is a highly flexible laminate designed for applications that require installation with some bend radius. It is much more flexible than standard TLY-3 fiberglass reinforced substrates. The flexibility of TLY-3FF is comparable to that of chopped fiber reinforced PTFE laminates but with a lower loss tangent. TLY-3FF has been engineered to provide the dimensional stability typical of the standard fiberglass reinforced TLY-5 Series and been designed for improved laser via formation relative to traditional TLY-3 glass reinforced laminates.
