More than 30 years later, carbon fiber material was also widely used in the freediving field, and T300 material became the ideal choice for many dive manufacturers and continues to be used to this day.

To this day, there are still many freediving flippers made of T300 because of its high stability and moderate quality (today) and reasonable price. Some manufacturers have also started to use higher grade materials. For example, the familiar Italian company C4, which launched the SIDERAL series at the end of 19, uses HT ALU15T material, which is several orders of magnitude stronger and more modest than T300. More manufacturers choose T700 / T800 also let the flippers reflect the relatively superior performance.

The carbon fiber material allows divers to have a more energy efficient experience when exercising compared to traditional rubber, silicone, fiberglass, etc. It also significantly improves the efficiency and power of kicking flippers. You know, for a long time in the past, rubber silicone material was the main choice of flipper manufacturers. More athletes are also getting better competition results with the help of new equipment (which is only one of the conditions, of course).

This is an example of how material innovation works in our lives, and it allows us to better love our favorite sports.

Here I will make a brief explanation of the common parameters of carbon fiber materials, (here we take Toray products as an example, essentially there is no unified parameter standard in the carbon fiber industry, and because of Toray's leading position, basically other manufacturers are named according to Toray's standard or approximate naming)

If you want to understand a flipper, you must first understand its flipper, and a flipper, the material occupies 80% of its cost.

T700SC-12000

Product model: T300,T700,T800, these 3 are currently the most used in the field of free diving, you can simply understand the iphone 7.8.10, the number is bigger, theoretically better performance.

Strength: refers to the performance of the uniform maximum load-bearing capacity per unit area

Modulus: the performance of the material after stretching to restore, the higher the modulus, the greater the tensile force can be withstood, you can understand the resilience requirements of the webbed sheet.

Density: the density of oil is less than water, so it floats on the water surface, carbon fiber density is greater than water

Weave: straight weave, horizontal weave, diagonal weave, you imagine the next weave bamboo basket.

Sizing amount: glue content

Silk bundle: grab a handful of hair and a chopstick, both are a handful, but the number is not the same

Carbon content: the essence of carbon fiber is the result of high-temperature carbonization of fibers

After reading this, I believe you will have a more comprehensive knowledge of your flippers.
