Title:
SHOCK-ABSORBING MEMBER FOR AUTOMOTIVE VEHICLE AND BODY STRUCTURE OF AUTOMOTIVE VEHICLE
Document Type and Number:
WIPO Patent Application WO/2014/106924
Kind Code:
A1
Abstract:
Non-continuous fiber reinforced layers (54) are laminated onto both sides of a continuous fiber reinforced resin layer (53) formed by causing continuous fibers (61, 62) arranged in a grid pattern to be bonded together using a first thermosetting resin, the non-continuous fiber reinforced layers (54) being formed by causing non-continuous fibers (63) oriented at random to be bonded together using a second thermosetting resin. A shock-absorbing member has great strength against a shock load impacting from a first or second direction, whereas when a shock load impacts from a diagonal direction, the grid of continuous fibers (61, 62) undergoes out-of-plane deformation and the intersections of the continuous fibers (61, 62) rupture, which reduces the strength thereof. However, by making a length (L2) of the non-continuous fibers (63) greater than a length (L1) of a diagonal line of each cell of the grid of the continuous fibers (61, 62), the grid shape of the continuous fibers (61, 62) can be effectively strengthened by the non-continuous fibers (63) when a shock load impacts from the diagonal direction, with out-of-plane deformation being mitigated, and it is possible to increase the shock-absorbing effect by increasing the strength of the shock-absorbing member against compressive failure.
