Abstract
Official abstract text for this publication.
An impact protection plate is provided for mounting on the structure of an aircraft. The impact protection plate includes a first layer, close to the aircraft, made of a fiber-reinforced plastic having a wave-shaped pattern of alternating elevations and depressions, the transverse tensile strength of the fiber-reinforced plastic being greater than 50 MPa. The impact protection plate includes a second layer situated on the first layer, remote from the aircraft, and is made of a fiber-reinforced plastic, the elongation at break of the reinforcement fibers being greater than 3%.
First claim
Opening claim text (preview).
What is claimed is: 1. An impact protection plate, comprising: a first layer, configured for mounting close to a vehicle, made of a fiber-reinforced plastic having a wave-shaped pattern of alternating elevations and depressions, the transverse tensile strength of the fiber-reinforced plastic being greater than 50 MPa; and a second layer situated on a side of the first layer remote from the vehicle, wherein the second layer is made of a fiber-reinforced plastic, an elongation at break of reinforcement fibers of the fiber-reinforced plastic being greater than 3%, wherein the reinforcement fibers of the second layer have a higher elongation at break than reinforcement fibers of the fiber-reinforced plastic of the first layer. 2. The impact protection plate according to claim 1 , wherein a thickness of the first layer is in a range between 0.4 mm and 0.8 mm, and a thickness of the second layer is in a range between 0.9 mm and 2.0 mm. 3. The impact protection plate according to claim 1 , wherein the impact protection plate is fastened to a structure of the vehicle in a region of wave troughs of the first layer, viewed from the direction of the vehicle structure. 4. The impact protection plate according to claim 3 , wherein the second layer includes an opening in flush alignment with a location of the fastening to the vehicle structure, to allow access to the fastening from outside of the impact protection plate. 5. The impact protection plate according to claim 4 , wherein the opening is closed by an elastic cover. 6. The impact protection plate according to claim 1 , wherein the impact protection plate has recesses for extensions on a structure of the vehicle. 7. The impact protection plate according to claim 6 , wherein the recesses are covered by protective covers fastened by an adhesive connection at a side of the second layer facing the vehicle. 8. The impact protection plate according to claim 7 , wherein a circumferential thermoplastic weld connection is on a side of the second layer facing away from the vehicle, along a joint between the protective cover and the second layer.
