Continuous filament mat (CFM) is the most commonly used reinforcement, but chopped strand mat (CSM) with thermo-deformable binders allows the production of preformed reinforcement shapes and is becoming more common. 

Processing. Reinforcement, shaping, and cure of vinyl esters is quite similar to processes described earlier for polyesters (Sec. 3.1.3.1.3).

Lan et al (2009) in their study used a fibre-reinforced shape-memory polymer composite in a deployable hinge as discussed, but little information on the space environment properties was given. 

With respect to the research in this field, all-polypropylene (PP) composites have been extensively studied. Hine et al. investigated the influence of fabrication parameters that control the hot-compaction behavior of woven-oriented PP [23,24], The results indicated that molecular weight, crystallinity, reinforcement shape and the weave style are important for controlling the composites performance. Alcock et al. created unidirectional all-PP composite laminates from co-extruded three layer tape of PP (with a copolymer homopolymer copolymer structure) via filament winding [12]. The specific mechanical properties were comparable to those reported for a commercial unidirectional glass fiber reinforced PP.

Properties of composites are strongly dependent on the properties of their constituent materials, their distribution and the interaction among them. The composite properties may be the volume fraction sum of the properties of the constituents or better properties. Apart from the nature of the constituent materials, the geometry of the reinforcement (shape, size and size distribution) influences the properties of the composite to a great extent. The concentration distribution and orientation of the reinforcement also affect the properties.
