Abstract

A front end body structure (3) has a front wall portion (4) which forms a front surface (4b) in a front-rear direction (Da) and has edge portions which form an opening portion (4a) opened; and a ceiling wall portion (5) which is continuous with the front wall portion (4) and forms a ceiling surface (5a) facing an upper side. In t front wall portion (4), side edge portions (41, 42) on both sides in the width direction (Dw) and an upper edge portion (40) on the upper side among edge portions surrounding the opening portion (4a) have a multi-axial fiber-reinforced plastic material in which at least two directions along the outer surface are set as a fiber direction. At least a partial region of the ceiling wall part (5) including a central portion in the width direction (Dw) has a core material sandwiched between the multi-axial fiber-reinforced plastic materials.

First claim

What is claimed is:

1. A front end body structure which forms an end portion in a front-rear direction of a vehicle, the front end body structure comprising:
a front wall portion which forms a front surface facing one of forward and rearward directions and has edge portions forming an opening portion opened toward the one of the forward and rearward directions; and
a roof wall portion which is continuous with the front wall portion and forms a roof surface facing upward of the vehicle in the vertical direction,
wherein, in the front wall portion, side edge portions on both sides of the vehicle in a width direction and an upper edge portion on an upper side in the vertical direction among edge portions surrounding the opening portion have a multi-axial fiber-reinforced plastic material in which at least two directions along outer surfaces of the side edge portions and the upper edge portion are set as a fiber direction,
wherein a lower edge portion of a lower side in the vertical direction among the edge portions of the opening portion has a uniaxial fiber-reinforced plastic having the width direction as the fiber direction,
inner side edge regions, which directly face the opening portion in the side edge portions, are formed only by two parts of the multi-axial fiber-reinforced plastic material, and
an inner upper edge region, which directly faces the opening portion in the upper edge portion, is formed only by the multi-axial fiber-reinforced plastic material.

2. The front end body structure according to claim 1 , wherein the front wall portion has a multi-axial fiber-reinforced plastic material in which at least two directions obliquely intersecting each other in the width direction and the vertical direction are set as the fiber direction.

3. The front end body structure according to claim 1 , wherein a connecting portion which connects the front wall portion and the roof wall portion is formed only by the multi-axial fiber-reinforced plastic material.

4. The front end body structure according to claim 2 , wherein a connecting portion which connects the front wall portion and the roof wall portion is formed only by the multi-axial fiber-reinforced plastic material.

5. The front end body structure according to claim 1 , wherein at least one of the side edge portion and the upper edge portion includes a core material sandwiched between two parts of the multi-axial fiber-reinforced plastic material.

6. The front end body structure according to claim 2 , wherein at least one of the side edge portion and the upper edge portion includes a core material sandwiched between two parts of the multi-axial fiber-reinforced plastic material.

7. The front end body structure according to claim 3 , wherein at least one of the side edge portion and the upper edge portion includes a core material sandwiched between two parts of the multi-axial fiber-reinforced plastic material.

8. The front end body structure according to claim 4 , wherein at least one of the side edge portion and the upper edge portion includes a core material sandwiched between two parts of the multi-axial fiber-reinforced plastic material.

9. The front end body structure according to claim 1 , wherein the lower edge portion has a core material sandwiched between two parts of the uniaxial fiber-reinforced plastic.

10. The front end body structure according to claim 9 , wherein the lower edge portion has the uniaxial fiber-reinforced plastic sandwiched between two parts of the multi-axial fiber-reinforced plastic material.

11. The front end body structure according to claim 1 , wherein at least a partial region of the ceiling wall portion including a center portion in the width direction has a core material sandwiched between two parts of the multi-axial fiber-reinforced plastic material.

12. A vehicle comprising:
the front end body structure according to claim 1 ; and
a vehicle main body fixed to the front end body structure.

13. The front end body structure according to claim 10 , wherein an inner lower edge region, which directly faces the opening portion in the lower edge portion, has a core material sandwiched between the two parts of the uniaxial fiber-reinforced plastic, the two parts of the uniaxial fiber-reinforced plastic being sandwiched between the two parts of the multi-axial fiber-reinforced material.

14. A front end body structure which forms an end portion in a front-rear direction of a vehicle, the front end body structure comprising:
a front wall portion which forms a front surface facing one of forward and rearward directions and has edge portions forming an opening portion opened toward the one of the forward and rearward directions; and
a roof wall portion which is continuous with the front wall portion and forms a roof surface facing upward of the vehicle in the vertical direction,
wherein, in the front wall portion, side edge portions on both sides of the vehicle in a width direction and an upper edge portion on an upper side in a vertical direction among edge portions surrounding the opening portion have a multi-axial fiber-reinforced plastic material in which at least two directions along outer surfaces of the side edge portions and the upper edge portion are set as a fiber direction,
the two directions are inclined at 45° with respect to each of the width direction and the vertical direction, and are orthogonal to each other,
inner side edge regions, which directly face the opening portion in the side edge portions, are formed only by two parts of the multi-axial fiber-reinforced plastic material, and
an inner upper edge region, which directly faces the opening portion in the upper edge portion, is formed only by the multi-axial fiber-reinforced plastic material.
