    Abstract: A method of treating fibers to improve resistance to high temperatures and relative humidity includes providing poly(p-phenylene~2,6-benzobisoxazole) (PBO) fibers, exposing the PBO fibers to an atmosphere of supercritical CO2 saturated with an epoxy silane, i.e. 3-glycidoxypropyl methyldimethoxysilane. The PBO fibers are subjected to a first pressurizing and heating stage at a first temperature (50°C) for a first period of time. The PBO fibers are then subjected to a second pressurizing and heating stage including increasing the temperature to a second temperature (110°C) and holding at the second temperature for an additional period of time. The PBO fibers include 2-5 wt% of 3-glycidoxypropyl methyldimethoxysilane after diffusing the CO2 out of the PBO fibers. The fibers are particularly useful in making lightweight body armor system components.

    Abstract: Uma etapa de vulcanização de pneus em autoclave com sistema de aquecimento for indução aplicada em processo de vulcanização/recauchutagem de pneus representa uma solução inventiva baseada no principío que materiais condutivos, metal e borracha, podem ser aquecidos através da tecnologia de indução de calor nas lonas de aço, ou na borracha dependendo das características construtivas e estruturais do tipo de pneu a ser vulcanizado e ainda dependendo do nível de condutividade e materiais empregados em sua fabricação, onde dentro deste novo processo tem-se que para uma peça na forma de pneu, o aquecimento indutivo é limitado às camadas superficiais deste e seu núcleo deve permanecer inalterado, onde esta condição apresenta vantagens na conservação de energia e na distorção reduzida à que fica exposta a peça "pneu", onde a penetração de calor nas áreas a serem vulcanizadas será efetuada por condução exigindo assim apenas tempo necessário para o calor atingir tal área. Em derradeiro uma vez carregado o equipamento autoclave com pneus preparados (Pp) a vulcanização do pneu pode ser obtida por indução externa (Ie), indução interna (Ii) e indução central (Ic), onde a escolha do tipo de indução aplicada é definida por parâmetros previamente conhecidos para o pneu preparado (Pp), tal como condutividade dos materiais aplicados e montados para auxiliar o processo de vulcanização; condutividade dos componentes estruturais do pneu; sistemas de indução adequados e posicionamento dos dispositivos de indução.

    Abstract: The present invention relates to a method for producing profile parts (31, 32), each having an L-shaped cross-section (33, 34), or an assembled profile part (43) having, in particular, a T-shaped cross-section. For this purpose a lay-up (1) made of composite fibre material is initially placed on a forming tool (3). In a further step, the lay-up is deformed by the forming tool (3) to form a profile (16) having a preferably U-shaped cross-section (21), the profile (16) thus exhibiting the book effect at each opposite end (24, 25). In a further step, the profile (16) is preferably cut in the longitudinal direction (26) in order to produce two profile parts (31, 32). The idea on which the invention is based is to allow the layers (2a, 2b, 2c) in the lay-up (1) to shift during the deformation process and subsequently to produce a substantially right-angled chamfered end (24 or 25) on the profile parts (31 or 32) by means of a cutting process. The disadvantageous formation of corrugations and complex clamping of the lay-up (1) are thus avoided.
