Lightweight high-pressure hydrogen storage tank based on carbon fiber reinforcement and method for manufacturing the same

Abstract

The application discloses a carbon fiber reinforced light high-pressure-resistant hydrogen storage tank and a preparation method thereof, and belongs to the technical field of high-pressure light hydrogen storage tanks, and aims to solve the technical problem that the lightness, air tightness and pressure cycle performance of the light high-pressure-resistant hydrogen storage tank in the prior art need to be further improved. The carbon fiber reinforced light high-pressure-resistant hydrogen storage tank comprises a barrier layer, a pressure-resistant layer and a protective layer arranged in sequence from inside to outside. The barrier layer comprises the following components in parts by weight: HDPE 70-80 parts, HDPE-g-MAH 15-18 parts, barrier filler 7-8 parts and additive 1-2 parts. The epoxy modified hollow microbeads, the epoxy modified poly-p-phenylene terephthalaldehyde and the modified carbon fiber are used to reinforce the epoxy resin, and then are matched with the barrier layer, so that the compatibility between the barrier layer and the pressure-resistant layer is improved, the density of the material is reduced, and the air tightness, the compressive strength and the normal temperature pressure cycle performance of the material are improved.
