There are some studies of nondestructive testing in wood or other solid materials based on stress wave technology.
There are some wave transmitting models and their application studies about wave propagation in the isotropy or anisotropy materials, such as the symmetrical guide wave propagation in holes[6], the SH wave propagation in anisotropy elastic solid[7], the free vibration wave propagation in wooden poles[9], ultrasonic wave application in the wood testing[8,10].

(1) The impact power absorption increased with the fiber content in material It indicated that the impact toughness of materials were also increased.
The softer materials, the better performance of impact energy absorbing, so is the cushion performance.
(3)The main compositions of the biomass buffer material are biodegradable, and there is no difficult degradable macromolecular materials be added in.
The biomass cushion material is an ideal replacement of materials that cannot be degraded.

Among these materials, polymers and their composites have gained significant attention due to their versatility, ease of processing, and tunable properties.
However, these additives are synthetic materials.
To turn waste into materials valuable, this work focuses on exploring the use of amethyst as a novel additive to enhance the properties of PVDF-HFP.
The integration of amethyst into polymer matrices presents an intriguing opportunity to enhance the functional properties of the composite materials.
