Moreover, the hand lay-up compression molding hybrid technique can be characterized as e ffi cient for the preparation of polymer matrix composites with a relatively high V f of over 50%. Remarkably, through the TGA experiments, the excellent thermal resistance of the basalt fibers, in the temperature range 30–900 C, was revealed.

Compression molding

Compression molding is a method of molding in which the molding material, generally preheated, is first placed in an open, heated mold cavity. The mold is closed with a top force or plug member, pressure is applied to force the material into contact with all mold areas, while heat and pressure are maintained until the molding material has cured.

Thermoplastic composites consist of a thermoplastic polymer matrix combined with various reinforcing materials such as short, long or continuous glass, carbon or other fibers. Main processes for the production of thermoplastic structural components include injection molding, compression molding, tape laying or placement and winding.

Thermoset polymer matrix

A thermoset polymer matrix is a synthetic polymer reinforcement where polymers act as binder or matrix to secure in place incorporated particulates, fibres or other reinforcements. They were first developed for structural applications, such as glass-reinforced plastic radar domes on aircraft and graphite-epoxy payload bay doors on the space shuttle.

Closed mold fabrication of Polymer Matrix Composites

2012/6/2Transfer Molding (Resin Transfer Molding) is a Closed Mold process in which a pre-weighed amount of a polymer is preheated in a separate chamber (transfer pot) and then forced into a preheated mold filled with a reinforcing fibers, taking a shape of the mold cavity, impregnating the fibers and performing curing due to heat and pressure applied to the material.
