Patent number: 10093081Abstract: A resin-rich peel ply that does not leave behind residual fibers after peeling and can work well with different resin-based composite substrates. The resin-rich peel ply is composed of a woven fabric impregnated with a resin matrix different from the resin matrix of the composite substrate. The peel ply is designed such that, upon manual removal of the peel ply from the composite substrate's surface, a thin film of the peel ply resin remains on the composite substrate's surface to create a bondable surface capable of bonding with another composite substrate, but no fibrous material from the woven fabric remains on the same surface.Type: GrantFiled: September 13, 2016Date of Patent: October 9, 2018Assignee: Cytec Technology Corp.Inventors: Yiqiang Zhao, Dalip Kumar Kohli, Kunal Gaurang Shah

Patent number: 9499666Abstract: Disclosed herein are monofunctional benzoxazine compounds having at least one electron-withdrawing group. The monofunctional benzoxazine compounds may be combined with one or more multifunctional benzoxazine compounds to form a unique benzoxazine blend. This benzoxazine blend may be combined with additional components such as catalysts and toughening agents to form a curable resin composition suitable for forming resinous films or composite materials. The presence of monofunctional benzoxazine improves the processability of the benzoxazine-based resin composition by reducing the viscosity of the resin composition, and results in improved tack and drape in the films and composite materials formed from the composition without the loss of modulus in the cured resin.Type: GrantFiled: March 21, 2013Date of Patent: November 22, 2016Assignee: Cytec Technology Corp.Inventors: Steven Ward, Mark Harriman
