摘要： Compositions are disclosed which are suitable for the preparation of thermoplastic syntactic foam intermediate and final products. These compositions comprise a slurry or putty containing thermoplastic particles, microballoons, and a non-solvent, optionally in the presence of suitable thickeners, binders, and surfactants. In a preferred embodiment, the composition contains particles of an engineering thermoplastic having a mean particle size less then about 100 .mu.m, microballoons, water as the non-solvent, and a thickener/binder which is a lightly crosslinked polyacrylic acid.

摘要： A riser for an archery bow is formed from a fibrous composite material, the matrix of which may be a high heat distortion thermoplastic polymer, a very high heat distortion thermoplastic polymer, or a combination thereof. The riser may incorporate a spine formed from a different polymer or composite than the rest of the riser, or from metal. A method for producing a riser for an archery bow includes the steps of introducing a polymeric composite into a mold from a first end of said mold to facilitate a particular orientation of components of said polymeric composite, molding the polymeric composite to produce a billet that approximates a net shape of the riser, and then machining the billet to the final shape of the riser.

摘要： An improved multifilamentary fibrous material is formed having particles of a matrix-forming thermoplastic polymer substantially uniformly dispersed among adjoining filaments in the absence of fusion bonding. The polymer particles initially are dispersed in an aqueous medium containing an effective amount of a dissolved polymeric binding agent and the viscosity of the medium subsequently is substantially increased to at least 50,000 cps. to form a gelled impregnation bath having a plastic flow characteristic with shear-thinning behavior wherein the polymer particles are substantially uniformly suspended. The resulting impregnation bath is caused to flow between the adjoining filaments of the multifilamentary fibrous material with a concomitant viscosity reduction which aids in the incorporation of the polymer particles. The concentration of the aqueous medium in the product is controlled to yield a uniform, handleable, drapable, tacky, and highly stable product. Upon the application of heat and pressure the improved product can be transformed into a fiber-reinforced composite article wherein the solid particles form the matrix phase.
摘要翻译：形成了一种改进的复丝纤维材料，其在不存在熔融粘合的情况下具有基本均匀分散在相邻长丝之间的基质形成热塑性聚合物的颗粒。聚合物颗粒最初分散在含有有效量的溶解的聚合物粘合剂的水性介质中，并且介质的粘度随后基本上增加至至少50,000cps。以形成具有剪切稀化行为的塑性流动特性的凝胶浸渍浴，其中聚合物颗粒基本均匀地悬浮。使所得的浸渍浴在复丝纤维材料的相邻长丝之间流动，伴随着粘度降低，这有助于引入聚合物颗粒。控制产品中水性介质的浓度以产生均匀的，可处理的，可悬挂的，粘性的和高度稳定的产品。在施加热和压力的情况下，改进的产品可以转化成纤维增强复合制品，其中固体颗粒形成基质相。
