摘要:
An FRP panel for an automobile, comprising a panel element to which a difference in rigidity and/or a difference in strength is provided between a first FRP layer on a first surface side and a second FRP layer on a second surface side on the opposite side of the first surface. The FRP panel for the automobile having a crushable structure suitable for absorbing impact can be realized, and the impact on a pedestrian in collision can be suppressed by properly absorbing the impact to protect the pedestrian.

Disclosed are a method for manufacturing a crank for a bicycle by bonding structural members to each other with an adhesive comprising; a step for applying the adhesive in a line-like or dot-like form in correspondence with an intervention region of the adhesive; a step for disposing a fabric in correspondence with the intervention region of the adhesive; a step for expanding the adhesive applied in a line-like or dot-like form in the fabric; and a step for bonding the structural members to each other with the adhesive expanded in the fabric, and a crank for a bicycle manufactured by the method. When the crank for a bicycle is manufactured by bonding the structural members to each other with the adhesive, the adhesive can be applied easily at a high accuracy and a good repeatability, variations of application condition and amount of used adhesive can be suppressed, and variation in quality can be suppressed.

A bonnet for an automobile, the bonnet having an outer made from FRP and an inner made from FRP, joined to the back-surface side of the outer, wherein the inner is separated into two parts in the forward and backward direction of a vehicle body. The bonnet can satisfy impact absorbing performance and predetermined required performance for deformation in a collision accident etc., and can improve easiness of production.

A propeller shaft for automobiles includes a cylindrical main body 1 made of FRP and joints 2 that are joined to the ends of this main body by press fitting, the main body 1 having a main layer 1a extending over the entire length thereof and including reinforcing fibers helically wound at an angle of ±5˜30° with respect to the axial dimension of the main body, and sub-layers 1b formed at the ends of the main body so as to be integral with and internally of the main layer 1a and including hooped reinforcing fibers. Each joint 2 has a slope 2c descending toward the joint surface between this joint and the main body 1, an erect surface 2d having an outer diameter not larger than the outer diameter of the sub-layers 1b and abutting the end surface of the associated sub-layer 1b, or a wedge 2f the tip of which is opposed to the interface between the main layer 1a and the associated sub-layer 1b. When an axial compressive load is applied to the joints 2, the slopes 2c, the erect surfaces 2d or the wedges 2f cause the main layer 1a and the sub-layers 1b to be separated from each other to cause rupture of the main body to proceed, thereby enabling the energy absorbing effect due to a crashable body structure to be realized.

A bonnet for an automobile, the bonnet having an outer member made from fiber reinforced plastic (FRP) and an inner member made from FRP, joined to the back-surface side of the outer, wherein the inner is separated into two parts in the forward and backward direction of a vehicle body. The bonnet can satisfy impact absorbing performance and predetermined required performance for deformation in a collision accident etc., and can improve easiness of production.

A thermoplastic composite plate material having a quasi isotropy comprises a thermoplastic resin having a melt viscosity of 1,000-15,000 poise and strip pieces each constructed of unidirectionally orientated reinforcing fibers and each having the specific dimensions of the thickness, the width, the length and the ratio of the width and the length thereof. The strip pieces are randomly distributed in plane parallel to a surface of the composite plate material. Since the composite plate material has good quasi-isotropic and high mechanical properties such as flexural strength, flexural modulus and impact strength, a composite product having good quasi-isotropic and high mechanical properties can be obtained by using the composite plate materials. Moreover, since the composite plate material has a good fittability, a composite product having a complicated shape can be easily molded.
