Abstract

The aim of this work is to integrate polypropylene/montmorillonite (MMT) nanocomposite matrices into conventional fibre-reinforced composites. Two types of composite have been considered: long fibre-reinforced composites from co-woven glass fibre and nanocomposite yarns, and glass mat reinforced thermoplastic (GMT) composites. The melt spun polypropylene precursor yarns contained up to 6 wt% MMT, leading to a 2 to 3 fold increase in axial stiffness, but more modest increases were observed in extruded films and compression moulded specimens. Corresponding stiffness improvements were obtained in GMT samples. However, significantly higher temperatures and pressures were required during preimpregnation to that observed with the unmodified matrix for a given processing time.

Composite material

A composite material (also called a composition material or shortened to composite, which is the common name) is a material which is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from mixtures and solid solutions.

Fibre-reinforced plastic

Fibre-reinforced plastic (FRP; also called fibre-reinforced polymer, or in American English fiber) is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass (in fibreglass), carbon (in carbon-fibre-reinforced polymer), aramid, or basalt. Rarely, other fibres such as paper, wood, boron, or asbestos have been used. The polymer is usually an epoxy, vinyl ester, or polyester thermosetting plastic, though phenol formaldehyde resins are still in use.

Ceramic matrix composite

In materials science, ceramic matrix composites (CMCs) are a subgroup of composite materials and a subgroup of ceramics. They consist of ceramic fibers embedded in a ceramic matrix. The fibers and the matrix both can consist of any ceramic material, whereby carbon and carbon fibers can also be regarded as a ceramic material. The motivation to develop CMCs was to overcome the problems associated with the conventional technical ceramics like alumina, silicon carbide, aluminum nitride, silicon nitride or zirconia – they fracture easily under mechanical or thermo-mechanical loads because of cracks initiated by small defects or scratches.
