Abstract
A graphene oxide/polypropylene heat-resistant high-strength composite profile and a preparation method thereof. The composite profile is a graphene oxide/polypropylene-based reinforced plain weave composite resin material, which is a heat-resistant high-strength composite profile prepared from a graphene oxide/polypropylene-based woven plain weave fabric and a fiber heat-insulating material which are made into a layered spacing structure composite flat net, and a resin composite material. The preparation method comprises the following steps: preparation of a graphene oxide/polypropylene-based woven plain weave fabric; preparation of a graphene oxide/polypropylene-based reinforced plain weave composite material; preparation of a multilayer graphene oxide/polypropylene-based reinforced plain weave composite material; and preparation of a resin composite material. The present invention has the advantages of convenient operation and excellent properties.
