Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of shear thickening material, and specifically relates to a shear thickening material framework structure capable of being deformed as a whole. BACKGROUND

[0002] Shear thickening material is a kind of material with special mechanical properties, between fluid and solid substance, and the Young's modulus of elasticity thereof increases with the increase of strain rate. Due to the special mechanical properties, it is widely used in the development of protective products in the field of explosion impact, such as bulletproof clothing. Related scholars also strive to better improve and utilize the performance thereof through a composite structure.

[0003] At present, the performance thereof is mainly improved through two structures: 1. fabric structure; and 2. "sandwich" structure. By combining the fabric with the shear thickening material, the overall strength can be improved, and the flexibility in the low-speed state is retained, and the bulletproof clothing adopts this kind of design. The "sandwich" structure is composed of upper and lower plate-shaped objects and a support structure in the middle, and the shear thickening material is filled between the upper and lower plates. This design not only can maintain the stable form of the shear thickening material, but also can improve the impact protection effect. The above two designs both utilize the characteristics of the shear thickening material to locally enhance the protection effect at the impact point, and the rest of the shear thickening material does not play a big role, and the impact is still concentrated in the local part.
