A material on-line identification system based on THz time-domain spectroscopy using VC was developed in this paper.
As the prototype of material detection application, the material whose corresponding type characteristic spectrum has already existed in the database could be well identified.
Fig.2.The diagrammatic flow sheet of the material identification process In order to test the effectiveness of the on-line detection system, the time-domain spectroscopy of all the samples in different situations of tabletting is tested for verification, its on-line detection and identification results are shown as the Fig.3: Fig.3.THz-TDS online material detection Conclusion The experimental results show that, for the material whose corresponding type characteristic spectrum has already existed in the database, the system of material on-line detection in this paper can better realize the function of material identification and detection.

As an important performance of woven composite materials, the impact resistance was researched by many material science researchers in the world. [1-3] This paper studied the low-velocity impact properties of three dimensional woven composite materials with orthogonal, quasi-orthogonal and angular interlocking structures, analyzed their characters through the curves of absorbed energy-displacement and discussed the influence of structure unit’s distribution on the low-velocity impact property of the 3D woven composites.
Forming of three-dimensional woven composite materials.
The composite materials were fabricated by means of VARI (Vacuum Assisted Resin Infusion) process [4].
As impact side changes, break time and break point of the composite materials change because the yarns absorbing energy are specific in three-dimensional woven composite materials.
