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.

In general, the well-known PEM materials are based on perfluorosulfonic acid membrane, such as Nafion® and Flemion®.
This power performance of DBFC is 50% higher than using commercial Nafion® materials.

This indicates that the failure criterion for brittle materials under compression is effective and applicable.
For the case of materials without pre-existing macrocracks, the failure criterion is identical with the well known Coulomb–Mohr criterion.

In the process, a lot of marine soft soil materials is inevitably encountered with in engineering practice.
The boundary condition such as the bottom of the marine soft soil materials model is fixed in all three directions and the side face of the marine soft soil materials is fixed in the X,Y directions.
Fig.2 The specific detail of the bucket foundation The properties of marine soft soil materials is listed in the following section, c=20kpa, , ,,the coefficient of friction between bucket foundation and marine soft soil materials is 0.2.
In the process, the marine soft soil materials of the passive region appears shear deformations, the bucket and the marine soft soil materials is separated with each other in the active region.
