<p>PURPOSE: To prevent a crack or a damage to a mechanical connection in a collision by incorporating a breaking length and an elongation at break in fibers, and embedding the fibers at an angle of a specific range to a pressurizing direction in a matrix. CONSTITUTION: Fibers or polyethylene fibers having a breaking length of at least 80 km and an elongation at break of at least 2% are arranged at an angle of±45 deg. to 90 to a pressurizing direction, and the other fibers are arranged at an angle of±0 to 30 deg.. In this case, the other fibers preferably have a low elongation at break (<5%), and are, for example, formed of carbon fiber or glass fiber. A matrix in which the fibers are embedded in a layer is preferably formed, for example, of plasticity persistence or thermoplastic matrix having a processing temperature up to 130 deg.C, such as, for example, an epoxy resin, polyester or other material being compatible with fiber or polyethylene fiber having a breaking length of at least 80 km and an elongation at break of at least 2%.</p> |
