Fiber alloy PVC modified material for unmanned aerial vehicle and preparation method thereof

Abstract

The invention provides a fiber alloy PVC modified material for an unmanned aerial vehicle. The material is prepared from the following components in parts by weight: 80-120 parts of polyvinyl chloride, 5-10 parts of compound stabilizer, 5-10 parts of PVC processing aid, 15-40 parts of alkali-free short glass fibers, 0-2 parts of a lubricating agent, 1-5 parts of a toughness agent, 5-10 parts of carbon fibers and 5-10 parts of a silane coupling agent. The fiber alloy PVC modified material for an unmanned aerial vehicle has light weight, high mechanical strength, excellent tensile strength, excellent tear resistance, good corrosion resistance, ageing prevention and excellent fire-proof performance, can meet the special requirement of an unmanned aerial vehicle for long storage service life at a severe environment to reduce the maintenance cost and cycle, and has simple and convenient integrated forming process, strong appearance designing applicability and relatively good application prospect.

Description

technical field [0001] The invention relates to the technical field of PVC modified materials, in particular to a PVC modified material of unmanned aerial vehicle fiber alloy and a preparation method thereof. Background technique [0002] At present, with the development of information technology, UAVs are rapidly used in various industries, such as reconnaissance aircraft and target drones for military use, and aerial photography, agriculture, plant protection, micro selfie, express transportation, and disaster relief for civilian use. , observing wild animals, monitoring infectious diseases, surveying and mapping, news reports, power inspections, disaster relief, film and television shooting, creating romance, etc., have greatly expanded the use of drones themselves, and developed countries are also actively expanding industry applications and development. man-machine technology. [0003] As an important part of the UAV, the UAV fuselage carries various sensors, navigatio...

AI Technical Summary

Problems solved by technology

Most of the existing drones are made of polystyrene foam or balsa wood skin plus FRP. If polystyrene foam is used, the polystyrene foam needs to be cut in the process of forming the curved surface of the fuselage. The cutting process requires high requirements and takes a long time, which increases the preparation cost of the UAV body. At the same time, the foam is easily corroded by glue, and after forming, it is easy to absorb water and get damp, resulting in deformation of the shape and reducing the strength of the UAV structure; If it is made of balsa wood skin and FRP, the material is relatively thick, resulting in excessive weight of the body after forming, which seriously reduces the load capacity of the drone, and the parts are relatively fragile in low temperature environment and are easily damaged during use.
