摘要:
Thermosetting resins are provided that are toughened with an irradiated thermoplastic toughening agent and which have reduced levels of solvent-induced micro crack formation. The thermoplastic toughening agent is treated with a sufficient amount of high-energy radiation (e.g. electron beam or gamma rays) to cause a reduction in solvent-induced micro crack formation in the cured resin when compared to the same toughened thermosetting resin in which the non-irradiated version of the thermoplastic toughening agent is used.

Thermosetting resins are provided that are toughened with an irradiated thermoplastic toughening agent. The resins have reduced levels of solvent-induced micro crack formation and do not lose their adhesiveness when attacked by solvent. The thermoplastic toughening agent is treated with a sufficient amount of high-energy radiation (e.g. electron beam or gamma rays) to cause reductions in solvent-induced micro crack formation and solvent-induced loss of adhesiveness when compared to the same toughened thermosetting resin in which a non-irradiated version of the thermoplastic toughening agent is used.

摘要:
In an editor a plurality of valid start points are determined. Based on the plurality of start points a user may select one of the points. When a user selects one of the points, the editor determines at least one valid end point. The user may then draw a line between the selected point and a valid end point. As a result of the connection between the two points a new environment is created in the editor.
摘要:
The processing window for thermosetting resins that contain particulate hardeners is prolonged using the combined steps of heat-treating the resin to form a low-viscosity resin mixture in which the particles are dissolved and then molding the low-viscosity resin mixture at temperatures below the dissolution temperature of the particles to infuse a fibrous preform. The infused resin preform is heated to the curing temperature of the resin to provide final curing of the resin.

摘要:
A new user-friendly game editor allows game players with little or no experience to create new games or game levels. Game element structures can be “drawn” using an “auto completion” feature that automatically functionally connects and/or arranges chosen game elements to provide a visually pleasing environment that is easily navigated by game characters. Such technology can allow an end user game player with little or no technical background to easily develop game levels that are fun to play and do not suffer from any significant defects or other problems that would decrease ease of navigation, functionality or amount of fun. The user may share the authored game with other users via a network so other users can retrieve the game and play it on their own game playing devices. Users can provide feedback concerning the fun and functionality of the game. Good feedback can entitle the game author to recognition including for example bonus points. Bonus points can be redeemed for items listed in an online catalog, which in turn can be used to author ever more interesting game play levels.
摘要:
One or more layers of structured thermoplastic polymer (14, 16, 24), such as a light weight veil of thermoplastic polymer fibers (14, 16, 24), are located within the interleaf zone of laminates that are composed of fibrous layers and thermosetting resin (12, 22). The thermoplastic veils (14, 16, 24) are used in the interleaf zones as a replacement for thermoplastic toughening particles.
