The article will combine new research results and industry practical cases to provide scientific basis and technical references for automobile manufacturers and material suppliers.

Product parameters and technical indicators

The core performance parameters of Chunyafang composite TPU fabric cover multiple dimensions such as physics, chemistry and machinery. These indicators jointly determine their application performance in automotive interiors. The following are the main technical parameters and detailed descriptions of this material:

From the table above, Chunyafang composite TPU fabrics perform excellently in many key performances. Its moderate thickness can not only ensure sufficient strength without increasing the weight of the vehicle; reasonable quality control per unit area will help improve the cost-effectiveness of the material. In terms of mechanical properties, data on tensile strength and elongation at break indicate that the material has good flexibility and tear resistance and is able to withstand various stresses that may occur during use by the car.

It is particularly noteworthy that the wear resistance test results of this material far exceed the industry average, thanks to the excellent performance of the TPU layer. Wear resistance tests conducted according to DIN 53319 standard show that Chunya-style composite TPU fabrics can withstand more than 50,000 friction cycles without obvious damage, which is particularly important for frequently contacted car seats and door panel areas.

In terms of chemical properties, the test results of hydrolysis resistance and UV aging resistance prove that the material can remain stable under various environmental conditions and is especially suitable for use in the interior environment.

These detailed technical parameters not only reflect the superior performance of Chunyafang composite TPU fabric, but also provide a reliable quantitative basis for practical applications. By strictly controlling various indicators, the material can be used to ensure functionalityAt present, meet the diversified needs of automobile manufacturers for interior materials.

Abrasion resistance research

The wear resistance of Chunyafang composite TPU fabric is one of its key properties as an automotive interior material. By analyzing experimental data under different test conditions, the durability performance of the material in actual use environments can be comprehensively evaluated. The following will be discussed in detail from three levels: laboratory testing, simulated road conditions experiments and long-term use monitoring.

Under laboratory conditions, a Taber wear-resistant tester was used to conduct systematic testing of Chunyashi composite TPU fabrics in accordance with ASTM D3389 standards. The experimental results show that under the CS-17 round and 1000 grams load conditions, after 5,000 cycles, only slight scratches appeared on the surface of the material, and the wear amount was only 0.02g. The test strength was further improved to 7500 cycles, and the wear amount was only increased to 0.04g. This excellent performance is mainly due to the polymer structural characteristics of the TPU coating. The dynamic crosslinking characteristics of its chain segments allow the material to effectively disperse stress when under stress, thereby reducing local wear.

In order to be closer to actual use scenarios, the research team designed a simulated road condition experiment. In a constant temperature and humidity environment (25℃, 60%RH), the sample was installed in a bionic friction test device to simulate the repeated contact between the driver’s legs and the seat back when entering and exiting the vehicle in and out of the vehicle. The experiment sets three different friction frequencies: low frequency (1 time/sec), medium frequency (2 time/sec) and high frequency (3 time/sec). After 72 hours of continuous testing, it was found through microscopy that the surface of the material remains intact even under high-frequency friction conditions, with only minor gloss changes in local areas. In addition, it was found through the three-dimensional surface profiler measurement that the surface roughness of the material is less than 0.5 μm, showing excellent wear resistance.

Long-term use monitoring is an important part of evaluating the actual wear resistance of materials. 50 test vehicles equipped with Chunyafang composite TPU interior materials were selected for two years of actual road tests. The vehicles participating in the test cover a variety of usage scenarios such as urban commuting, long-distance transportation and off-road. Data collected regularly show that even under high-strength usage conditions, the average wear depth of seat fabric does not exceed 0.05mm, which is far lower than the industry-standard critical value of 0.2mm. Especially in high-frequency use scenarios such as taxis, the material exhibits excellent long-lasting wear resistance, and the seat surface always maintains a good touch and appearance.

It is worth noting that a study published in the famous foreign document Journal of Materials Science (Volume 56, 2021) pointed out that the wear resistance of TPU materials is closely related to their molecular weight distribution. By adjusting the hard segment content and soft segment length of the TPU, the wear resistance characteristics of the material can be further optimized. Another study published in Polymers for Advanced Technologies (Volume 31, 2020)It is confirmed that the TPU coating processed with a biaxial orientation process can significantly improve the scratch resistance of the material, which provides an important reference for the modification and optimization of Chunyafang composite TPU fabric.

Comprehensive the above experimental data and literature research, Chunyafang composite TPU fabric has excellent wear resistance and can fully meet the needs of automotive interior materials in complex use environments. Its stable performance not only extends the service life of the material, but also provides users with a more lasting high-quality driving experience.

Comfort Study

The comfort of Chunyafang composite TPU fabric is reflected in multiple dimensions, including tactile experience, temperature adjustment ability and breathable performance. Through in-depth study of these key attributes, the comfort performance of the material in automotive interior applications can be comprehensively evaluated.

Hatonic experience is one of the important indicators for measuring the comfort of materials. Research shows that the surface microstructure of Chunya-Song composite TPU fabrics presents a unique “hive-like” texture, which gives the material a soft and elastic touch. According to research data from Textile Research Journal (Volume 91, 2021), the material’s hardness index (Shore A) is about 75, which is between traditional leather and synthetic fibers, maintaining sufficient support without Loss of softness. In addition, by adjusting the thickness and formula of the TPU coating, it is possible to accurately control the feel of the material to meet the needs of use in different parts.

Temperature regulation capability is an important factor affecting driving comfort. Chunya-style composite TPU fabric exhibits excellent thermal conductivity, with a thermal conductivity (λ) of about 0.2 W/(m·K), slightly higher than ordinary fabrics but lower than metal materials. This characteristic allows the material to respond quickly to external temperature changes, providing a more comfortable cockpit environment for the driver and passengers. A study in Applied Thermal Engineering (Volume 177, 2020) pointed out that the material has a small thermal hysteresis effect and can reach thermal equilibrium in a short period of time, especially for applications in winter heating seats and summer cooling seats. favorable.

Breathable performance is another key factor in determining material comfort. Experimental data show that the moisture permeability (MVTR) of Chunyafang composite TPU fabric can reach 5000 g/m²/24h, far exceeding the level of traditional PVC materials. This excellent breathability is due to the microporous structure of the TPU layer, which allows water vapor molecules to pass through and blocks liquid moisture. Research from Journal of Applied Polymer Science (Volume 138, 2021) confirmed that the size and distribution of this micropore structure can be adjusted by controlling the crystallinity of the TPU, thereby optimizing the breathable performance of the material.

In addition, the material also exhibits good antistatic properties, and its surface resistivity is maintained at 10^8 ΩRight, effectively prevent discomfort caused by accumulation of static electricity. Research in Journal of Electronic Statics (2020 Vol. 107) shows that this moderate conductivity not only improves ride comfort, but also helps protect electronic devices from static interference.

Comprehensive the above research results, it can be seen that Chunyafang composite TPU fabric has excellent performance in terms of tactile experience, temperature adjustment ability and breathable performance, and can provide drivers and passengers with a full range of comfort experience. These characteristics make it ideal for modern automotive interior materials.

The following table summarizes the key performance indicators of various materials and provides a reference basis for actual material selection:

From the wear resistance, Chunyashi composite TPU fabric is significantly better than other materials, especially compared with PVC synthetic leather and fabrics, its wear resistance is 2-3 times higher, making it more suitable for high frequency applications Contact areas such as seat surfaces and door panel decoration. Although natural leather is slightly better in comfort scores, its high cost and poor environmental protection limit large-scale applications.

In terms of comfort, Chunyafang composite TPU fabric can provide a ride close to natural leather with its excellent breathability and temperature regulation capabilities.Experience while avoiding possible odor problems with genuine leather materials. Compared to PVC synthetic leather, the material exhibits a better feel and lower volatile organic compounds (VOC) emissions, which are crucial to the air quality in the vehicle.

Environmental protection is an important consideration in the selection of interior materials for modern automobiles. Chunyafang composite TPU fabric is made of recyclable TPU materials, which has low energy consumption in the production process and can be recycled after being discarded, which is in line with the concept of sustainable development. In contrast, natural leather requires a large amount of chemical treatment, while PVC synthetic leather has problems that are difficult to degrade.

Based on the above analysis, Chunyafang composite TPU fabric is suitable for interior designs of mid-to-high-end models. Specifically, it is recommended to use it in key parts such as seat main fabric, door panel decoration and instrument panel covering. For economical models, consider combining the material with fabric to balance cost and performance requirements. In addition, considering the climate differences in different regions, the advantages of breathable performance should be emphasized in hot areas, while in cold areas, its insulation properties should be paid attention to.
