Manufacturing method of composite material ultra-light solar cell substrate

Abstract

The invention belongs to the technical field of a stratospheric aircraft and especially relates to a manufacturing method of a composite material ultra-light solar cell substrate. The method comprises the following steps: according to design requirements of the solar cell substrate, preparing edge reinforcing ribs, wherein the edge reinforcing ribs comprise long edge reinforcing ribs, short edge reinforcing ribs and round corner reinforcing ribs; according to laying requirements of the solar cell substrate, preparing carbon fiber pre-preg cloth; according to the requirements of the solar cell substrate, pre-burying and fixing connection members at the corresponding positions of an aramid paper honeycomb, wherein the connection members are obtained by machining a polycarbonate sheet; and paving epoxy resin adhesive films onto the upper and lower surfaces of the pre-burying-finished aramid paper honeycomb. The advantages are that a new method is provided for preparing the solar cell substrate of the stratospheric aircraft; the process is relatively simple; the finished product is good in quality, high in intensity and light in weight; and the manufacturing method is high in manufacturing efficiency.

Description

technical field [0001] The invention belongs to the technical field of stratospheric aircraft, and in particular relates to a manufacturing method of a composite material ultra-light solar cell substrate. Background technique [0002] In recent years, various countries are conducting research on various types of stratospheric aircraft. The stratospheric airship is a new type of low-cost, low-energy stratospheric aircraft. Its solar cell array plays a key role in energy control and has become a key technology. Generally, the solar cell substrate is made of carbon fiber board or glass substrate for its strength and ultra-lightness. The difference between the solar cell substrate is nearly 1 times, and the solar cell substrate is nearly 3 times heavier than the ultra-light solar cell substrate at the same strength. There are problems such as sandwich structure composite delamination and bonding bubbles. It is necessary to study a lightweight , High-efficiency composite materia...
