Performance comparison of carbon fiber trekking pole and aluminum alloy trekking pole

Carbon fiber trekking poles and aluminum alloy trekking poles who have more performance advantages

My point is:

1. Sports carbon fiber is very mature and can produce high-end trekking poles. The performance of carbon fiber trekking poles surpasses aluminum alloy trekking poles.

2. The main reason why carbon fiber trekking poles are not popular is still the price is too high, not the immature performance

CARBON (carbon fiber) has been widely used in the aerospace and aircraft industries due to its light weight, corrosion resistance, and insignificant physical response to temperature changes (not obvious thermal expansion and contraction characteristics), but due to its low fracture strength, it has been Become the biggest controversy whether to start using carbon fiber. After many years of experimentation with top skiers, KOMPERDELL uses carbon fiber armrests through a special ring-shaped multi-layer arrangement called "carbon fiber F200+ technology". Without increasing the weight of the armrests, KOMPERDELL starts the resistance of the armrests. Strength increased from 50KG to 200KG.

Multi-layer 100% carbon fiber: Through the special multi-layered carbon fiber, the stiffness of the hand battle is increased, but the weight of the hand battle is not increased.

Carbon fiber has an intuitive understanding:

1. After the broken carbon fiber trekking pole tube, everyone can clearly see the fiber, and the cross section also has the color of the carbon fiber

2. Carbon fiber is mostly a multi-layer structure. Different textures can be seen on different layers, and the positions of different layers can be replaced, which will affect the strength and performance of carbon fiber tubes.

3. How to tell if it is carbon fiber trekking pole?

Sometimes it is difficult to distinguish the material of the tube from the color of the outside of the trekking pole. For example, the following picture shows that the surface is metallic silver.

Teach you a way: you can take off the sheath as shown in the figure: if it is a carbon fiber tube, the cross section and the inside are all ink-colored, and some can even see the texture of the inner wall of the tube

4 There is also a way to distinguish whether it is a carbon fiber trekking pole, that is, weighing (removing parts, pole tip cover):

The weight of aluminum alloy trekking poles, either 7075 or 60 series, are mostly between 260G-360G.

The characteristics of carbon fiber are light. Under normal circumstances, the weight of a 50% carbon fiber trekking pole is less than 210G, and the upper and lower errors are plus or minus 10 grams. If the weight of carbon fiber trekking poles exceeds 220G, you should pay attention. Carbon fiber synthetic materials are composed of carbon fiber, glass fiber, and epoxy in a certain ratio. Overweight carbon fiber trekking poles are likely to be replaced by low-grade carbon fiber tubes. For example, the actual carbon fiber content is only 30%, but the nominal 50% or higher.

5. Then on the premise of distinguishing whether it is a carbon fiber trekking pole, we further discuss how to distinguish the carbon fiber content of the carbon fiber trekking pole.

Accurate carbon fiber content still needs laboratory testing, so ordinary consumers can't tell? Let me introduce a method here, maybe I can help. Just scrape the carbon fiber rod with a knife and take a look at the carbon fiber powder:

A. Remove the trekking pole loop, the test of this part will not damage the appearance of the trekking pole

B. Scratch on the cross section

C. Scrape on the surface

Look at the powder, the tube with high carbon content, the powder is like pencil shavings, the finer the powder is, the better the uniformity; the tube with low carbon content, there are white larger debris in the powder, of course, this discrimination method requires some experience.

TITANAL high density aluminum alloy

TITANAL is also widely used in the aerospace and aircraft industry, because it is a part that needs to be in contact with the limit for a long time. It is also an important material in sports equipment. It has the characteristics of high density and light weight. The strength can be as high as that of steel but the weight is only one third of that of steel.

On the basis of the general TITANAL, after the second refining and heat treatment, the 7075-T6 material produced is the material of most KOMPERDELL battles.

I will say that different materials have their own advantages and disadvantages, and they do not replace each other completely.

Aluminum alloy is cheap, but heavy, and the penetration rate is high, everyone knows him well

Carbon fiber is expensive, light, high-strength, and has a low penetration rate. Everyone does not understand his performance well, and there are many misunderstandings. .

1. Manufacturing materials. Today, the vast majority of trekking poles on the market are made of high-grade aluminum that can withstand the harsh environment. In addition, manufacturers have also applied titanium alloys and other composite materials. The advantages of these materials with advanced technology are ultra-light weight and strong durability. The application of these types of materials in the manufacture of trekking poles can effectively extend their service life.

2. Length and number of stretchable sections. Whether it is telescopically adjustable is the latest popular theme in the trekking pole market. The telescopic portability of the trekking pole depends on how many sections the entire trekking pole body is composed of. The greater the number of sections, the smaller the trekking pole can be compressed. At present, the form of the three-section pole is the most portable and safest choice of telescopic trekking poles. In comparison, although the overall strength of the two rods is higher, they are more likely to break due to the small number of sections. The unadjustable rods undoubtedly have the best strength, but how to carry them when not in use will be the most troublesome problem.

3. Material of cane head. When it comes to the material of the stick head, durability is the primary concern. Carbide heads and tungsten alloy heads are undoubtedly the most durable stick heads on the market, they can ensure a better shape of the stick head, and compared with other material heads, the service life is longer. Steel rod heads are the most popular because of their price, but their wear is the fastest. If you are crossing some sensitive ground and want to increase the grip of the cane, you can use the detachable rubber cane cap, which is also the function of most mountaineering poles.

Another function to consider when purchasing trekking poles is whether the pole head can be replaced. Some trekking poles are equipped with this function, so that when the trekking pole is stuck by the surface such as rock cracks and cannot be detached, the stick head and the stick body can be detached. After all, it is much cheaper to replace the cane head than to replace the entire cane.
