Manufacturing of thermoplastic composites

At the outset of the composites industry, the matrices were unsaturated polyesters. Then other thermosets were developed but some years ago the manufacture of thermoplastic composites began and their development is now faster than that of thermoset-based composites.

The use of thermoplastic composites offers several advantages compared to thermoset materials. Their useful properties include high impact resistance, damage tolerance, low price, and recyclability. Hybrid yams containing both reinforcing fibers such as flax fiber and the thermoplastic matrix in the form of fibers such as PP filaments are easier and quicker to manufacture [139-141].

Most of the resin systems used in commodity composites are slight modifications of the standard commercial mol ding grade material. Usually certain selected properties, such as purity or molecular weight range or distribution, are enhanced or carehiUy selected. In addition, special additives, such as flow controllers, thermal stabilizers, or antioxidants, are often added by the resin manufacturer prior to shipment. Many of the conventional or commodity-type resins used in thermoplastic composites are Hsted in Table 1 and the preparation of each of these is described. AH resins and blends described in the hterature are not Hsted, and the synthesis described is not the only procedure available, but is usually the most common commercial process.
