[0002] Luggage is a tool that people carry when they travel. Hard-shell luggage is more resistant to falling. Soft-shell luggage is usually lighter and more elastic than hard-shell luggage. However, the zipper position of soft-shell luggage is more secure. It may explode due to too many items inside, or the fragile items in the box are easily damaged due to external extrusion. Nowadays, the suitcase has been developed in the direction of lightness and durability. PE materials have appeared, and the characteristics of PE materials are better than those of ABS. Lighter and more impact-resistant, it can be combined with a soft case. It has the safety of a hard case and the portability of a soft case. However, once these materials are cracked by the sewing line, they must be scrapped and cannot be repaired, and they do not have flame retardancy. performance, once a fire breaks out, it will bring losses to people

Abstract

The invention discloses a preparation method of a resin based fiber reinforced composite. The resin based fiber reinforced composite is prepared from polystyrene, polyphenyl ether, wollastonite powder, reinforced fibers, flexibilizer, a foaming agent, polydimethylsiloxane, a silane coupling agent, a curing agent and antioxygen, and the resin based fiber reinforced composite is obtained through the processes of high temperature melting, laying reinforced fibers, pressing or squeezing with a double-roller press and the like. The preparation method has the advantages that the composite can be used for a safe box, a safe case or a high-end trunk; the flame retardant and heat preservation performance is further achieved, high toughness and tensile property are achieved, and the resin based fiber reinforced composite is simple in process and easy to manufacture.
