He has made significant contributions to the field of composite materials, particularly through his innovative resin systems. With a total of 5 patents, his work has advanced the performance and durability of high-temperature applications.
Latest Patents
One of Sidney's latest patents is for an elastomer modified bis-maleimide resin. This novel bis-imide matrix resin system is especially useful for high-temperature, high-performance graphite fiber composites. The addition of 1 to 15 percent of compatible elastomers, such as polyether sulfones and bis-phenol linear homopolymeric epoxies, reduces microcracking of composites and increases transverse strength. The resin system comprises 50 to 95 percent by weight of ethylenically unsaturated bis-imides, which include a low melting mixture of maleimides of aromatic amines and a minor portion of maleimides of aliphatic amines. Additionally, 5 to 35 percent by weight of a diunsaturated low-temperature cross-linking agent, such as divinyl benzene, is included to gel the bis-imide at low temperatures. The presence of a trifunctional curing agent improves room temperature tackiness, heat resistance, and cross-link density.
Another significant patent is for a bis-maleimide resin with an inhibitor. This resin system also comprises 50 to 95 percent by weight of ethylenically unsaturated bis-imides, focusing on a low melting mixture of maleimides of aromatic amines and a minor portion of maleimides of aliphatic amines. The inclusion of a diunsaturated low-temperature cross-linking agent helps reduce stress between the matrix resin and the surface of the reinforcing fiber, thereby minimizing the formation of microcracks. The stability of the resin at room temperature is enhanced by the presence of an oxidation inhibitor, making it particularly useful for high-performance, graphite fiber reinforced composites.
