Development and Application of Domestic Aerospace-Grade Composite Hot Bonder Instruments
Chinese version hot bonder for aviation grade composites is a national composite material repair equipment developed in response to the call of"China's high-end equipment localization alternative application".According to the research progress of hot bonders at home and abroad,combined with the development and application requirements of equipment,six key points in the development process of domestic hot bonders,such as maintenance applicability,temperature parameters,vacuum degree,control technology,man-machine interaction and reliability were studied.This paper introduces the development process of a domestic heat repair instrument by selecting the equipment index,designing the operation interface layout,constructing software structure and program running logic.Domestic hot bonder has formed a series of products,including single-zone versions,dual-zone versions and multi-functional versions,and the product performance indicators have met and exceeded similar foreign products.The domestic hot bonder adopts a full Chinese graphical interface,which is easy to operate.The multi-functional version of the product integrates two functions of composite bonding repair design and repair implementation,which supports the efficient calculation and acquisition of composite repair design scheme under the field environment,and provides technical support and equipment support for the frontline technicians to carry out the in-situ repair of aircraft composite structural damage.After the preliminary assessment and application by the air force maintenance factories,troops and colleges,the domestic hot bonder can completely replace the foreign hot bonder products.
