Problems solved by technology

However, disadvantages exist with such knitted textile composite structure according to the preferred embodiments as disclosed in '052.
Firstly, it is observed that under multiple impacts, the knitted textile composite structure according to the preferred embodiments as disclosed In '052 may exhibit unsatisfactory energy-absorbing performance.
In particular, the three-dimensional knitted textile composite structure may collapse at the first impact and therefore lose a substantial part of its energy-absorbing capacities.
Furthermore, it is also observed the process of spraying and curing thermoset resin onto the fabrics is time consuming.

Embodiment Construction

[0045]FIG. 1 illustrates an exemplary three-dimensional sheet-like textile composite structure 100 with energy-absorbing capacities under multiple impacts. The textile composite structure 100 has a generally planar base 103 and a plurality of projections 105 extending from the base 103. In the exemplary embodiment, each projection 105 has a grid-domed shape with a conical sidewall 107 and a generally flat top 109. Furthermore, each projection 105 defines a space (not shown) where the sidewall 107 and / or the top 109 may collapse under impacts. FIGS. 1B and 1C are respective top plan view and cross sectional view of the textile composite structure of FIG. 1A.

[0046] The textile composite structure 100, at least the projections 105, includes a textile and a matrix material. More specifically, in the exemplary embodiment, the textile structure 100 is made from non-woven fabric materials impregnated with thermoplastic matrix materials.

Abstract

A three-dimensional cellular textile composite structure with energy-absorbing capacities under multiple impacts is provided. The cellular textile composite structure includes a base, and at least one progressively collapsible projection extending from the base for absorbing energies under the multiple impacts. The projection includes a non-woven textile material supported in a thermoplastic matrix material such that the projection is capable of retaining energy-absorption capacity at least after the first impact of the multiple impacts.

Description

BACKGROUND [0001] 1. Field of the Invention [0002] The present invention relates to three-dimensional textile composite structures with energy-absorbing capacities under multiple impacts, and to the manufacture and use thereof. [0003] 2. Background of the Invention [0004] Three-dimensional textile composite structures have been widely used for energy absorbing purposes. For example, U.S. Pat. No. 6,536,052, issued to Xiaoming Tao et al. on Mar. 25, 2003 and entitled “Safety Helmets with Cellular Textile Composite Structure as Energy Absorber,” discloses a porous textile composite structure with high energy-absorbing capacities. Preferred embodiments of '052 suggest spraying and then curing thermoset resins onto knitted fabrics for achieving the desired textile composite structures. [0005] However, disadvantages exist with such knitted textile composite structure according to the preferred embodiments as disclosed in '052. [0006] Firstly, it is observed that under multiple impacts, t...
