Benefits of technology

This patent is about a method for making a strong and durable material using a special resin material that can be woven with reinforcing fibers. The resulting composite has a constant thickness and can be used to make things like armor or helmets. The method involves heating the resin material to a high temperature and then weaving it with the reinforcing fibers. The resulting material has good adhesion and drapability. The patent also describes a specific type of resin material that can be used for this method.

Problems solved by technology

The resulting composite may have a constant thickness as a result of the failure of the structural fibers to soften.

Abstract

The present teachings contemplate forming a reformable epoxy resin material into a monofilament having a denier of from about 50 to about 5000 and a glass transition temperature of less than about 200° C.; loading one or more monofilaments onto a spool; co-weaving the one or more monofilaments with a reinforcing fiber to form a woven material, the reinforcing fiber having a glass transition temperature of greater than 200° C.; heating the woven material to form a composite to a temperature so that only the one or more monofilaments soften but the reinforcing fiber does not.

Description

TECHNICAL FIELD[0001]The present invention pertains generally to reformable epoxy resins for use in monofilament fibers, and more particularly to drapable materials formed using said fibers and composite structures formed therewith.BACKGROUND[0002]Industrial fiber materials often require means to hold or bind materials together. Often, thermoplastic materials (e.g., fibers) are used to stitch or bind the materials together. However, such current methods include a number of drawbacks including but not limited to the incompatibility of typical thermoplastics with secondary materials (in particular epoxy-based composite materials), lack of sufficient blending, yarn showing through composite surfaces, behavior of thermoplastics upon sanding or cutting of secondary materials, rigidity of typical thermoplastics and lack of reformability of typical thermoplastics.[0003]Reformable thermoplastic polymers having at least one epoxide group have been described in U.S. Pat. Nos. 5,115,075; 4,438...
