Thermoplastic-based blends are widely used in military applications for various reasons. One of the reasons is the need to have the best technology to win a battle. During World War I when aerial combat first took place, canvas and dope (shellac) covering for airplane wings and fuselages was used, and that is one of the earliest uses of composite materials. By the time the war ended, BaekeUte (invented in 1907) was in commercial production. A canvas and phenolic resin composite was being widely used for airplane and marine components when World War n started. 

A recently introduced polycarbonate-based blend offers a low coefficient of thermal expansion. This new thermoplastic is designed for large sheet applications such as doors or siding. Its high dimensional stability will eliminate warping from exposure to varying temperatures.

Currently, great efforts are being made to produce thermoplastic starch with improved mechanical properties, low water sensitivity and better compatibility with other polymers, which is of fundamental importance to the production of TPS-based blends. Studies have also been carried out on multilayered systems, as an interesting way to overcome some TPS drawbacks [58]. These... 

Lyocell tibers have been explored in blends. Chang et al. [141] prepared Lyocell based blends. Poly(vinyl alcohol) (PVA), poly(vinyl alcohol-co-ethylene) (EVOH), and poly(acrylic acid-co-maleic acid) (PAM) were used as fillers in blends with lyocell produced through solution blending. The results showed that blends with PVA exhibit the best tensile properties. Thus, Lyocell fibers have recently been used as reinforcement for thermoplastic fiber composites.

As in the preceding section, the polymers to be bonded were PVC, ABS, and the thermoplastic polyester blend Xenoy. In addition microscope slide glass was also studied. Surfaces of these materials have been shown to be capable of widely differing acid-base interactions. The PVC was an unplasticised polymer (MW = 54,000 g/mol) from Synergistic Chemicals, Inc. It contained 5 phr of Advastab TM-821SP thermal stabiliser. The ABS (Cycolac AR 3501), was a moulding grade, commercial product of GE Plastics, Inc. The same source supplied the Xenoy blend the exact composition of this material was not determined. 

Let us first review various thermoplastics used in automotive applications. These include nylon 6,6-based blends (e.g., nylon 6,6-PPO), glass-filled nylon 6,6 with without impact modifiers, homo- and copolymers of PP, polybutylene terephthalate (PBT), polyethylene (PE), bis-phenol A polycarbonate (PC), acrylonitrile-butadiene-styrene (ABS), PC-ABS blends, glass-filled PP, and ABS. 

Thermoplastic polyolefin (TPO) blends of metallocene-based polyolefin elastomers (POE) with polypropylenes have gained commercial significance because of the improved melt flow and toughness compared to the conventional TPOs based oti EPR or EPDM blends made with high melt-flow PP (Toensmeier 1994). in comparative tests with 70/30 PP/elastomer blends, the blends with POE maintained ductile behavior at —29 °C even with high melt flow index PP (MFl = 35), while the corresponding EPR-based blends were brittle with PP of MFl = 20. In addition, they showed improved knit-line strengths.
