Structural thermoplastic composite

The penetration of thermoplastics and thermoplastic composites ranges from the totality of the considered parts - for example, bumpers or fuel tanks where metals are nearly ousted -down to applications that are widespread but with only a few consuming part types, such as wire supports, and promising outlets, for example glazing or structural parts. Well-established applications are, for example ...

The development of anionic chemistry over the past 30 years has led to the emergence of new processes and products of Industrial Importance, the most significant being a family of thermoplastic elastomers. These unique elastomers are presently commercialized by Shell Chemical Company as Kratons and by Phillips Chemical Company as Solprenes. Their uniqueness is the result of deliberate design of the polymeric structure and composition. 

Recendy, storm doors have been constmcted of advanced thermoplastic composites. Stampable, glass-mat reinforced polypropylene sheet is used to create a high strength outer skin. These compression molded skins are welded together using a friction or ultrasonic process then injection molded with a polyurethane foam core to produce an insulated structure. New technology for window frames incorporate the pultrusion of frame channels to produce a thermoset composite channel that can be filled with fiber glass for further insulation enhancement (12,31,33,34,48,49,54—56,60—67). 

The silicone semi-IPN structure imparts unique behavior to thermoplastic composites without affecting mechanical strength and stifihess. Apart from the direct effects associated with the incorporation of thermoset character into a thermoplastic, the structure has particular value by functioning as (1) a nonmigrating internal lubricant, (2) a shrinkage and warpage modifier, (3) a fiow modifier, and (4) a release agent. As a polymer-polymer composite,... 

To ascertain control of the molecular weight, structure and composition, block copolymers are usually synthesized in anionic polymerization. The block copolymers of commercial interest are specifically prepared from monomers that upon polymerization yield immiscible macromolecular blocks, a smaller one rigid and the other flexible. The rigid blocks form physical crosslinks that upon heating above the transition point make the copolymer to flow. Thus, these materials belong to the growing family of thermoplastic elastomers. 

Laminar composites are combinations of several layers of composite sheets that are bonded together. Polyolefin sandwich structures are a laminar composite. They are composed of two or more layers of polyolefin with a different material in between the layer (long fiber mat or short fiber). Sandwich panel and laminar composites are common methods for thermoset resins and thermoplastic composites. This simple method can be applied to natural fiber-reinforced thermoplastic composites using the hot press method. The addition of a reinforcement material between polyolefin layers does not require extrusion or injection molding and minimizes fiber degradation [35, 36].

Bioactive giasses have been deveioped since 1969 [67] and continuous bioactive glass fibers since 1983 [68-69]. Very recentiy [70], bone bioactive glass fibers were found to bond to bone tissue and help bone tissue growth when they are preferentialiy placed on the surface of a thermoplastic composite while carbon fibers are used to stiffen the core of the structure.
