Fin Blades - T300 Naked Carbon Fibre (Big Feet Bone - Blue)
Strong but flexible, the latest technology for high performance fins. The Penetrator Carbon range offers the ultimate in fin performance.
Identical profile to the composite blade, 72 cm working blade length, 25 degree toe angle for efficient surface fining and extremely lightweight at 325 grams with wide water channeling rails. This means less fatigue and lower oxygen consumption for divers who appreciate the advantages that can be gained from high performance equipment.
Penetrator blades are manufactured using a proprietary Capillary Closed Moulding System (CCMS). This system is a culmination of 25 years’ composites manufacturing experience applied to fin blade development over the past 8 years by Penetrator Fins founder Larry Gray.
The process eliminates the requirement for secondary processing materials used by other manufacturers producing an outstanding surface finish on both sides of the blade and reduces waste. These 2 outcomes alone produce a blade with a smoother flex curve and reduces the environmental footprint of the manufacturing process.
All metal production tooling has been produced in-house utilising Penetrator Fins CAD design and CNC manufacturing capabilities. Mould temperatures are digitally controlled through the process to ensure the specially formulated resin system reaches its ultimate mechanical properties. Only certified carbon and glass fibres issued with a certificate of conformity (usually reserved for aerospace applications) are used. Full process control over these parameters ensures engineering performance measures are consistently achieved.
Carbon Fibre blades receive a protective layer of Kevlar 49 multi-axial reinforcement in the tip of the blade to prevent chips and cracking. This system is unique to Penetrator blades. Kevlar is an extremely resilient and flexible material providing added impact resistance while allowing full flexibility of the blade tip.
Once moulding is complete fin blade profiles are CNC machined to an accuracy of .01mm. Penetrator Fin’s proprietary rubber water rail is then added with cyanoacrylate adhesive in purposed built pneumatic clamping jigs.
Logos are added using hard wearing epoxy inks or In Mould Labelling (IML) techniques during manufacture. Our graphics are digitally printed onto lightweight media and incorporated during the moulding process using IML.
A digital OCM image is embedded into the fin blade on the top and bottom of the fin using In Mold Labeling technology that will not wear off.
