Acoustic Absorption of Natural Fiber Composites
Table 1
Advantages and disadvantages of natural fibers [
17,
18].
| Advantages | Disadvantages |
| Are biodegradable, cheaper, and eco-friendly and have low specific weight. | Have lower antifungus, durability, moisture, and fire resistant qualities. | Are abundantly available and high electrical resistant. | Have a negative impact on climate change (CO2 absorption). | Have good thermal and acoustic insulating properties. | Exhibit lower acoustic absorption compared to synthetic fibers, due to a larger diameter. | Have low toxicity and less human health hazards during processing and handling. | Have poor fiber-matrix adhesion and moisture resistance which causes increase in volume for swelling of the fibers. |
