By forming the holes, the matrix resin of the fiber sheet on both sides is integrated through the holes, increasing the peel (adhesion) strength.Furthermore, by applying matte processing to the plastic film, the matrix resin can be integrated through the holes. It is characterized by a composite light shielding material that can prevent improper flow of resin during thermal bonding to obtain a uniform thickness and also prevent continuous fibers from opening due to the stress of the resin flowing through the holes.

きる。 The above embodiment is characterized by the large number of holes 1a in the plastic film 1 as the core material.
The purpose is to improve the properties by forming and mat processing.
A large number of holes are formed in the plastic film as the core material, and the matrix resin of the prepreg sheets on both sides is integrated through the holes, thereby increasing the peel strength of each layer and improving the properties as a composite light shielding plate. Although this is already known, in this example, the plastic film 1 as the core material is further matte-treated to prevent opening of the continuous fibers, to obtain a uniform thickness, and to have excellent light-shielding properties. A composite light shielding material can be provided. That is, by matte processing the plastic film 1,
When the prepreg sheets 2-a and 2-b are thermally bonded together, the flow of the matrix resin in the planar direction is strongly resisted, and firstly, the matrix resin flows in the direction of the continuous fibers, making the thickness uneven. You can prevent this from happening. Secondly, it is possible to prevent the continuous fibers from being biased in the opening direction (direction substantially perpendicular to the fiber direction) due to the flow of the matrix resin in the direction of the large number of holes, thereby greatly improving the light-shielding property. . Also, thirdly, both prepreg sheets 2-a,
The adhesion between the plastic film 1 and the core material 2-b can also be improved by the matte-finished finely uneven surface in areas other than the multiple holes 1a.
